lithium battery knowledge

Lithium batteries are a type of batteries that use lithium metal or lithium alloy as the positive/negative electrode material and use a non-aqueous electrolyte solution. In 1912, the lithium metal battery was first proposed and studied by Gilbert N. Lewis. In the 1970s, M. S. Whittingham proposed and began to study lithium-ion batteries. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. With the development of science and technology, lithium batteries have become the mainstream.
Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable. The fifth generation of rechargeable batteries, lithium metal batteries, was born in 1996, and its safety, specific capacity, self-discharge rate, and performance-price ratio are superior to those of lithium-ion batteries. Due to its own high-tech requirements, companies in only a few countries are producing such lithium metal batteries.

    Analysis of the importance of battery maintenance and common problems

    Since many computer rooms are unattended, uninterrupted power supply is a prerequisite for the safe and effective operation of equipment in the computer room under unmanned conditions. As a backup DC power supply unit, the battery plays a very important role in the unmanned machine room. Valve-regulated sealed lead storage battery is a kind of lead storage battery. Because of its good uniformity, small self-discharge, no leakage of acid, no leakage, no frequent water maintenance, long service life, etc., it is widely used in the communication industry. Used as a backup power supply. However, if it is used improperly or lacks proper maintenance, it will often shorten its service life and be scrapped in advance. Correct use and maintenance work can extend the life of sealed lead-acid battery packs.
