Battery Review – Just another WordPress weblog

The development of electronic technology, high energy to the mobile power demand. Lithium ion battery is a kind of ideal portable power, small volume, light weight, high voltage, discharge is big, etc. Since 1990, the world’s first SONY corporation lithium ion battery, by 2001, the market every year around 4 million such batteries used for pure consumer electronic products. The camcorder laptop computers, mobile phones, etc. More than 95% using lithium-ion secondary battery power.

1, lithium-ion secondary battery principle of work

Used for lithium-ion secondary battery anode materials mainly layered structure LiCoO2, LiNiO2 spinel structure and the structure of these materials LiMn2O4, determines the Li ion can exist in its freedom in ion channel. Various types of carbon materials is currently the most widely used rechargeable lithium ion battery anode materials, they also allow freedom of lithium ion in the meantime the embedded and embedded.

In LiCoO2 system of lithium-ion secondary battery for example is given to illustrate its working principle. Generally, lithium-ion secondary battery consists of positive, electrolyte, diaphragm and negative. When the battery anode, lithium ion from LiCoO2 layer structure, the combining elements of Co + to + Ⅲ increased by approximately 400mah Ⅳ, oxidation reaction, and lithium ion battery electrolyte migrate through the anode carbon anode in the layer structure of materials and carbonization connate into LiCX. When the battery is connected to the load in two electrodes, which occurred on the reaction occurs for charging NiFanYing reaction. The diaphragm is between the positive electrode reaction, the diaphragm can pass through, but not allow ion battery, at the same time, when the electronic through some extent across the micro short circuit, the diaphragm is blocking the protection function.

2, the structure of li-ion rechargeable battery

Current appear on the market lithium-ion secondary battery are divided into two kinds, one kind is square rechargeable lithium ion batteries, a cylinder for lithium-ion secondary battery.

These cells are in cylindrical lithium-ion secondary battery mature manufacturing processes, and on the basis of electronic products in order to adapt to the development trend of light and developed. Cylindrical and square lithium-ion secondary battery components is roughly same, including the general component: positive and negative, the diaphragm, positive, negative and positive lead wire terminals, relief valve, insulation slices, battery shell, etc. Lithium-ion secondary battery structure schematic as shown in figure 2. Lithium-ion secondary battery naming also cylindrical and square two, one of three letters with cylindrical naming and 5 digit, before two letters lithium ion battery (LI), after a letter (R), cylindrical before two numerals with mm in diameter, the maximum for the unit after three figures to 0. LMM for maximum height, such as LIR18650 means for 18mm, high 65mm diameter cylidrical lithium ion battery. After three letters in the square and six numerals, before two letters lithium ion battery (LI), after a letter (S), the former square two numerals with maximum thickness of mm, two numerals with mm for the unit width, hind two Numbers to the maximum height for mm, such as LIS043048 means to 4mm 30mm width, thickness, high 48mm square lithium ion battery.

3, lithium-ion secondary battery status and future development

Japan is the world’s largest producer of lithium ion batteries, also have such batteries patent most populous nation. Lithium electricity industry in China, but later start developing very rapidly, and according to the incomplete statistics, China has roughly 200 scale of production and related lithium ion battery materials company, annual production of billions of lithium ion batteries, insiders expect China will soon surpass Japan to become the world’s production of lithium-ion secondary battery.

Current lithium-ion secondary battery acid lithium cobalt in a positive, negative material is carbon materials, the production process has been quite battery, the battery performance can completely monomer battery to meet the design requirements, and the manufacturing cost also have very good control of lithium-ion secondary battery, the actual production costs are lower than those of the same energy nimh rechargeable batteries (currently the world’s production of nimh batteries are less). But, to make the positive lithium cobalt acid lithium ion batteries, safety performance is poor, especially in some harsh conditions using explosion accidents to. Using lithium manganese acid, phosphoric acid lithium cobalt nickel and iron lithium cobalt materials instead of a new generation of acid lithium battery materials can be a very good solution to the safety performance, also can further reduce production cost, this technology is expected in the lithium ion battery power to get a promotion.

Recently, the South African solar energy companies to take days to group visits, and days can be ordered on-site solar energy storage cell group.

South Africa is Africa’s electricity-producing country in the past has always been sufficient electricity, electricity cheap, but over the past two years, frequent nationwide electricity shortage. National saving as an important measure, the South African government in May last year the country began actively promoting solar energy, issued a series of preferential policies to vigorously popularize solar power, solar lights and solar lights and other traffic.

China will launch a new occupational safety and occupational health standards and requirements on examination of blood and urine cadmium cadmium to join. Earlier, huizhou GP super industrial health and safety and occupational health examinations, regular found about 110 human blood cadmium content exceeds domestic relevant departments, set standards and watch list, the employee need to leave the hospital for observation and prevent to contact. 22 people in two weeks contains quantity of cadmium has fallen to normal level, and other employees to discharge, the current situation is good. Affected employee in the appointed hospital medical expenses by huizhou GP super liable for payment, and huizhou GP as to the super also get paid employees. Batch Cadmium industrial accident is not above.

Workers response
This is not a physical examination, but the factory routine before because there are many workers at blood cadmium exceeds, out of workers to factory workers are required for blood and urine cadmium check. Cadmium, Factory workers, until the first three days, work for the workers agreed to factory inspection. And more than 1,000 workers only plant more than 500 people, it still has a lot of more than 500 people in the factory, not just into contact with cadmium employees. Check out there who are overweight, 121. This more than 100 workers from June 19, 20 in hospital, on June 28, some workers are required from the hospital. It also means they only 8 days in hospital, no two weeks. The hospital worker in 22 discharge cadmium-rich nor to normal. Other employee still exist aching, waist sour backache dizziness, headache wait for a symptom. Company will not pay to hospital staff, we have 1000 multivariate monthly income per month, now only send 400 yuan.
2 company statement

Huizhou GP super in 2001 has been approved by the international authentication, ISO14000 and license issuing agency is in that factory audit, safety, health and environment pollution and other aspects conforms to the international requirements. The third party audit report pollution levels in scope and every year.
Workers response
Although each year, but in the factory audit, temporarily notified prior to review the improvement, etc. Is approved by the old. Employee has not only in water, has workshop, until 2004 began with dust mask… Is this the safety and health of international and national standards?

At 19:30 on January 30, 2009, Guangzhou Donghua Road tragic events in specific locations for the Lenovo store. Therefore, the printing once “freedom of association” that the Department of Lenovo Mobile phone explosion.

However, in the February 1, Lenovo Mobile in South China’s relevant parties to confirm to reporters, said: “Lenovo’s mobile phones have been determined not to be.” The source said, as happened during the Chinese New Year holiday, so they also get news, multi-confirmation has been confirmed that an explosion of non-Lenovo mobile phones. However, the source said the explosion in the end did not know what brand mobile phone, “This shop is not what we think (mobile) employees, is the distributor side of the staff.”
According to informed sources, the cell phone is really not cottage machines, but the regular brand mobile phones, but the explosion is actually the battery, rather than mobile phones. Newspaper reporter was informed that staff the less fortunate, “has recently changed a battery, may be just to charge mobile phone battery good power, and then cell phone pocket on the chest To her surprise, a new mobile phone battery exploded and neck artery was severed. ”
Another source, allegedly branded mobile phones or for the regular foreign brands. However, Nokia, Motorola, Sony Ericsson said the stakeholders are aware of the matter. Stakeholders expressed their mobile phone mobile phone battery explosion is indeed an explosion, and the phone also separated by a layer of the relationship between the “mobile phone will not explode, but the battery will be.”
Phone hung on the chest
Battery explosion injuries of the most fierce
Maybe it is for convenience to take place, perhaps in order to prevent theft, many cell phone users will pull a rope hanging in the chest, or hides in the chest pocket, do not in the waist, and then lightly placed on or close to the thigh pants pocket. Unfortunately, however, after the explosion of cell phone batteries, cell phone installed in his chest that is the most insecure, most likely fatal.
With the January 30 South Road, Donghua mobile phone explosion took place is similar to June 19, 2007, Jinta County, Gansu Province, the camp of iron selected pairs of cities and towns of the mobile phone battery factory explosion occurred, the victim also because the mobile phone on the chest explosion led to broken ribs and punctured his heart died.
Same 2007, June 27, Guangzhou, there were two consecutive cell phone battery explosion. From the electric Mr. Bai Decai superficial chest was blown up, “the perpetrators” is a second-hand mobile phones; one in Yuexiu District to work Miss Bai Lingzheng Huarong damaged bridge of the nose leaving a 2 cm scars. Fortunately, two of the victims near misses, life worry-free.

DURACELL (DURACELL) brand was born in 1920, by a bold and bright young scientists Samuel Ruben (Samuel Ruben) and the other a young and wealthy manufacturer of tungsten filament wire Phillip Mallory (Philip Rogers Mallory) co-founded. The brand from a coincidence: the day, Lu had to Mallory’s experiment to find a used equipment, conversation, and mallory Rubens aware of the co-inventor and manufacturing talent, combining the strengths of an excellent opportunity for , which began their cooperation, which result is the birth of the battery Ba Jin. Samuel Reuben was the invention of the battery technology to make revolutionary changes.

“Duracell” the battery brand was officially adopted in 1964. Gillette acquired Duracell in 1996.

Duracell International, Inc. is the world’s manufacturing and sales leader in high-performance alkaline batteries. “Golden King” is the world’s most famous outstanding consumer brands. For people around the world, the “Duracell” The brand represents a high-quality battery products and constant innovation, aggressive marketing philosophy. Duracell alkaline batteries for its “excellent quality, durable power” of the superior quality and marketing the world’s nearly one hundred countries and regions. The same time, Duracell also produce and sell lithium batteries for high-power electronic products (such as cameras, portable computers and mobile phones, etc.)

“Duracell” lightning breaking mountain
Now, Duracell batteries and advertising painted on the streets of Chongqing, everywhere, the battery on the battery market in Chongqing had already shifted. However, people do not think of dream: Duracell batteries from entering the market to the occupation of Chongqing, Chongqing market, it only took six months. A new product within six months, they occupy such a big new market, be described as lightning-style “quick fix.” Well, it is lightning-style “quick-fix” Success What’s the secret? Quality? It is of course Duracell batteries to open up an important factor in market success, but people more praise is its unique marketing strategy.

Chongqing is the largest city in southwest China, Duracell batteries to open up the battery market in this great city of Chongqing, is to set up their own offices, or find a local trade agency? This is the U.S. manufacturers, is a very worthwhile question on the minds. After second thoughts, the smart Americans chose the latter. Because he knew that: the local agent of the economic conditions in Chongqing, a better understanding of people’s living standard, retail distribution of Chongqing, Chongqing, state of competition in battery market, people shopping habits, etc. are all familiar with, and they can be under these circumstances to take appropriate marketing strategy. This is for the United States Duracell batteries, battery market in Chongqing, “quick-fix” provides a prerequisite.

United States Duracell battery manufacturers looking for agents in Chongqing, Chongqing Carey trading company. Agency contract entered into after the trading company in Chongqing Carey, began to analyze the characteristics of Duracell batteries and Chongqing battery market specific circumstances. Duracell battery is a relatively good price of high-quality durable batteries. On the market in Chongqing, the battery very competitive in the market already has a “555″ brand, “Toshiba”, etc. and prices there are several, more than one dollar, two dollars more, more than triple and so on, but it is relatively inexpensive. In view of this situation, the company adopted a “three-step” type of marketing strategy: first consignment, second Distribution, the third step the terminal promotions.

Recently, CaoLu received consumer complaints, ms yao is reflected in a grocery store sales within the jurisdiction of the “white elephant” 5 alkaline battery quality problems. According to ms yao, because of her trip to prepare for digital camera, a backup battery to the grocery store in each section 2 yuan price bought three “number” 5 alkaline batteries, felt no money, no claim invoice or other receipts. The next day, he embarked on a journey of ms yao, when loading and bought a day after the battery, unexpectedly found a digital camera battery is low still hint, thus missed many beautiful scenery.

Upon receipt of the local appeal, ms yao contacted actively “white elephant” battery manufacturer Shanghai swan battery Co., LTD, elephants invite relevant personnel to reflect the store ms yao to deal with this.

Enter a grocery store, law enforcement personnel in glass eye saw the “put counter elephants” alkaline batteries. According to the grocery store operator CaoMou narrative, sales to ms yao “white elephant” 5 alkaline batteries are from the vendor door-to-door battery, each section for purchase price of $1, sold $2. CaoMou chose from vendors hand purchases, a white elephant “battery” is convenient, is to covet make more profits, therefore, to purchase the “white elephant” sham tort doesn’t care whether batteries. The battery Co., LTD, Shanghai elephants swan’s staff, CaoMou sales to ms yao and unsold “white elephant” alkaline batteries are fake products, industrial and commercial place for infringement of CaoMou selling fake tort “white elephant” alkaline battery case processing of behavior, and at the same time, CaoMou request refund ms. Yao corresponding

According to law enforcement, selling fake “number” of the battery, and mostly concentrated in a few stationery shops and small supermarket, small stores and sales of individual cells as small business premises. Stalls In the case of problem solving yao lady after CaoLu xiang, law enforcement personnel and jointly with the swan battery Co., LTD, Shanghai number of staff, who involves sales within the jurisdiction of the small business premises battery products in a two-day carpet inspection, check, another door 68 sham tort “elephants that sales of” 10, these business management are not out of stock, also say the vendor from door-to-door purchased, the purchase price is 1 yuan, and the price is 2 yuan

I remember in 2007 in March, and Big Brother with the tour in Guangdong Province, a beautiful area, talking about which stocks will bring more than 10 times earnings, the older brother recommended BYD, called an analytical study, I sides to enjoy the scenery while listening to his reasons, after hearing what I jotted down this BYD shares, came back would seriously study the stock, from the history of the development BYD to his product’s market share , to Wang Chuanfu the character \ a \ accomplishments \ ability to have made a detailed analysis of the study, found that the company is indeed a master beat his opponent’s magic, low-cost + high quality + low cost + management is good, the success of its electric car possibility to make an in-depth study, in order to accurately grasp, but also the composition of their iron battery, raw material composition, raw material production principles, made the success of scientific research, for insurance purposes, you can still see the production of batteries for understanding hydrogen storage alloy powder used in the expert consultation on the Wang Chuanfu’s side acquaintance consulting, consulting engineer of the relevant confirmed practicable want to buy, but go to Hong Kong accounts trouble, was delayed until after the news of Buffett’s shares , overnight drive to Shenzhen, the next morning to open an account with the Hong Kong to 14-15 yuan buying BYD, the investment returns over the past year there are five times the current 63.8 yuan also has four times more than fairly well, convinced 3 to 5 years later, at the XXXX yuan, the following elaborate on BYD’s research:
1, the investment principle: I have to value investing as the center, according to Graham, Buffett’s investment theory and the Art of War as an investment guide, analyze the market with investment value but are not overlooked stocks pulled up, and wait for the market to buy their own Matakura found that higher prices to test your own investment approach is right or wrong. The so-called “know ourselves and our ever-victorious”, we invest in a stock must be preceded by a clear understanding of the investments to ensure that their input will not be a loss of capital and profits substantially exceeded the average market level, in order to remain invincible.
We, as investors, is to take full responsibility for their own funds, if the investment is not correct, it will make their financial losses, thereby affecting their assets, affect your interests, affect your life. Therefore, before making any investments must go through rigorous analysis, that the value for money when you can invest in stocks. The so-called value investing, that is, the price lower than the value when purchased, according to Buffett’s philosophy, which was the price when the value of 70% of the investment to buy, only those with the right approach, coupled with rigorous analysis, so that you have to grasp the investment, the investment Yaoda sure the battle!

And, using the iPhone is identical with the built-in iPod player, so the user lithium battery design couldn’t additional equipped with battery for a rainy day.
According to foreign media reports, the telecommunications company Cingular testers, cell phone battery can maintain apple iPhone 40 minutes of time.
In the United States Cingular is the exclusive mobile iPhone, according to the testing personnel said: “now questions. Give mobile phone.” One problem is one of the battery time only 40 minutes.
And, using the iPhone is identical with the built-in iPod player, so the user lithium battery design couldn’t additional equipped with battery for a rainy day. In addition, the interface are often problems.
No doubt, the report aroused “apple fans. Someone says, the report’s authors is a journalist, not qualified to discuss technical problems, And someone said, call once more than 40 minutes, it must be mad.
Even if people say that 40 minutes of jobs have enough time, then ok, he himself will be immediately reduce his time on the phone.
In January, apple CEO Steve jobs in meeting the iPhone Macworld issued by phone. At the same time, Cingular became the iPhone exclusive provider in the American market.
According to the agreement, the mobile phone market in the iPhone after six months before, Cingular will become the sole mobile service provider iPhone. And after six months, the other operators can give mobile phone sales.
According to the apple is expected to give in 2008, mobile phone sales to be 10 million. But American research institutions, apple is expected to TBR likely target, predicted quota to 12 million.
