lifepo4 battery 3.2v 100ah.Lithium primary battery

　　Lithium manganese dioxide battery (CR)

　　Lithium metal is used as the negative electrode, manganese dioxide after heat treatment is used as the positive electrode, and the isolation membrane is made of PP or PE film. The cylindrical battery is the same as the lithium-ion battery separator, and the electrolyte is an organic solution of lithium perchlorate, cylindrical or buckle type. Batteries need to be produced in a dry environment with a humidity of ≤ 1%.

　　Features: Low self discharge rate, annual self discharge can be ≤ 1%, fully sealed (metal welded, lazer seal) batteries can meet a lifespan of 10 years, and semi sealed batteries generally have a lifespan of 5 years. If the work control is not good, this lifespan cannot be reached. Yiwei, which has done a good job in the development of cylindrical lithium manganese batteries, has now achieved automated production, and the batteries can be tested for short circuits, over discharges, and other tests without explosion.

　　Generally, on the motherboard of desktop computers, there is a button type lithium battery that provides weak current and can be used normally for about 3 years. Some hotels also use lithium manganese dioxide batteries for access cards, instruments, and meters, but their usage has been decreasing year by year in recent years.
