What is a lithium manganese battery?

Strictly speaking, lithium-manganese battery is a kind of battery in the lithium battery family, so the difference between lithium-manganese battery and lithium battery is not easy to define, because different types of lithium batteries will have different characteristics.

Lithium-manganese battery electrode reaction formula: (-) Li / LiClO4—PC+DME / MnO2 (+)

Battery anode reaction: Li → Li+ + e

Cathode reaction: MnO2 + Li+ + e → MnO2 (Li+)

Overall reaction: Li + MnO2 → MnO2 (Li+);

Lithium-manganese battery is currently the most used lithium button battery. It was first called mercury battery. Because of pollution and electric capacity, it has been gradually replaced by lithium-manganese formula. The basic voltage is 3.0V, and the maximum electric capacity can reach 1200mAH.

Lithium-manganese batteries, also known as lithium-manganese dioxide batteries, use manganese dioxide treated with special technology as the positive active material, metal lithium with high potential and high specific energy as the negative active material, and the electrolyte adopts an organic electrolyte with good electrical conductivity. Solution, the battery structure has two forms of full sealing and semi-sealing.

Due to the stable discharge curve of lithium manganese batteries, many high-tech products such as motherboards use it as a backup battery for memory.
