What is the safety knowledge of lithium battery?

It is described in "Play with My Camera Lithium Manganese Battery" by Zheng in "E-paper" 18 edition in 2003 published in Hubei province that charging test for lithium battery. After reading the article, readers doubt the opinion in the article. This paper puts forward the approach of lithium manganese battery recharged by occasional test. It's had better not following these opinions, nor widely promote.

My specialty is electrochemical engineering, in lithium battery professional manufacturer engaged in the design and production of battery in recent 10 years, have more understanding of the characteristic of all kinds of lithium battery. So it is necessary to introduce some of lithium-ion batteries use safety knowledge, in order to avoid many problems.

Lithium battery is a kind of new chemical power source is not popular, it has many advantages: the first is the high voltage (3.0 V to 3.0 V), the second is to use a wide range of temperature (45 ℃ ~ + 75 ℃), the battery is higher than the energy for ordinary zinc manganese battery (2 times), low self-discharge rate, storage capacity loss after five years of less than 10%).Lithium battery charging according to whether recycled into a cell and secondary battery. Lithium ion batteries are a secondary batteries, lithium manganese battery is a battery. A lithium battery according to the different chemical system can be divided into: lithium manganese dioxide series (C series), lithium - sulfur dioxide series (w) series, lithium - chloride series of sulfurous phthale in series (E), potassium (fluorinated carbon series (series B), and other species. Cameras with lithium CR123A battery is - manganese dioxide cylindrical battery, models for CR17340 international. Domestic manufacturers of alternative models for CR17335 CR123A, its performance with foreign battery is the same, the price is less than half of the imported products.

Lithium battery has inherent weaknesses: that is its high security requirements. Lithium battery national standard examination indexes have special battery safety performance, production must be strictly in accordance with the requirement of production and inspection. With the popularity of lithium batteries, ordinary users will also be necessary to know some knowledge of the safety of the lithium battery.

Due to the lithium battery used in lithium metal or lithium compounds, including one lithium battery is lithium metal. Metal lithium is very lively, under the normal temperature condition, lithium can react with many substances, so a lithium battery in the process of production, storage and use are more strict requirements. If you don't do what these requirements, it is possible to produce risk, the relevant report has also been reported.2001 IC telephone lithium-ion battery explosion took place in Wuhan, has caused quite a stir.
