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, 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

At present the development of mobile phone battery industry in a relatively primitive stage of that price, competing virtual standard capacity, and even most of the products is a typical “three noes” products, a large number of low-quality batteries shoddy, security, and frequent accidents seen in newspapers. The vicious competition in the industry led to the majority of enterprises in product development and brand promotion of inputs greatly reduced, and then one pile to take several different product brand names, and then one month and then re-sell not work a change in the name of selling, branding and development of the precipitation out of the question. Stable up to start from 2006, focusing on manufacturing high-quality commercial mobile phone battery in just three years, stability and achieve that One mobile phone battery brand in the industry and the minds of consumers has become the benchmark for high-quality commercial batteries. Stable up to, indeed the field of new generation mobile phone battery!

New generation of mobile phone battery! Stability over ANDIDA doing my part – no A Kid – Hong Kong’s stability over ANDIDA Battery

Stable up to 2009 through a variety of ways to create a more stable relationship with the dealer, and gradually the healthy growth of a common mechanism of cooperation. The first is to strengthen the industry has all along been neglected One terminal image-building, unobstructed platform for sales, followed by the service support and funding platform support, as well as One series of brand promotion activities in support, while a stable network of channels occupy up to realize the importance of present, the terminal will help dealers build networks, strengthen channels of competitive differentiation. As established only three years of mobile phone battery manufacturers to have such a visionary idea, really be called a new era of mobile phone battery industry pioneer.

At present fake “white elephant” batteries are more concentrated in some small stationery store, small supermarket, small department stores, individual stalls and other small-scale establishments. Pudong Branch of Commerce and Industry yesterday warned consumers to buy the best batteries to the regular stores, do not forget to request an invoice after purchase.

Recently, Ms. Yao Cao Road to the Pudong business of the complainant, said she was filming travel needs, Yuwei digital camera to prepare sections of spare batteries, then home to a nearby grocery store price of 2 yuan per session bought three “white elephants “No. 5 alkaline batteries. The following day, Ms. Yao then embarked on a journey, when installed, after you’ve bought some batteries, they discovered that digital cameras are still prompted for low battery power, and thus missed a lot of beautiful scenery.
Commerce and Industry of the receipt of her complaint, contact the “white elephant” with the manufacturer of the battery to store it at home. Jo said grocery store owner and sell it to Ms. Yao’s “white elephant” 5 alkaline batteries, all from the door in the hands of hawkers selling the battery section of 1 yuan each to buy them, and then the price of 2 yuan per session sales.

The “white elephant” cell-site identification of the manufacturer and sell Ms. Yao’s “white elephant” 5 alkaline batteries and are yet to sell a “white elephant” alkaline batteries are counterfeit goods, law enforcement officials immediately right Jo Sales fake “white elephant” behavior of the battery placed on file processing, the owner Ms. Yao money refunded.

Subsequently, the law enforcement officers in conjunction with “white elephant” battery manufacturer, the sales area the size of the battery 68 premises wife and children carried out a two-day inspection, was found selling fake “white elephant” battery operated 10 households, these households operate have to take no Jinhuo Dan, and these counterfeit batteries are also sent from the hawkers come to sell, and purchase price are 1 per month, priced at 2 yuan.
