How long is the life of 402030 polymer battery

When we talk about lithium manganese oxide, we say it is a spinel structure, which refers to the crystal shape of its application in lithium-ion batteries. When lithium manganese oxide is not used in lithium-ion batteries, there is also a layered structure. Relatively speaking, the spinel structure is more stable than the layered structure (although based on chemical properties, it seems that the stability of different shapes in geometry can also be thought of), so the spinel structure is still used in practical applications.

The number of cycles of lithium manganese oxide ion batteries can generally reach more than 800 times, and the life is not short compared to traditional lead-acid batteries.

In addition to lithium manganese oxide, lithium cobalt oxide and ternary lithium-ion battery positive electrodes are also spinel structures, but the spinel structure of lithium manganese oxide is very distinct from its two similar ones, that is, the advantages and disadvantages are very prominent. Its advantages are: low temperature resistance, good rate performance, and relatively easy preparation. The disadvantages are: the material itself is unstable and needs to be mixed with other materials, poor high temperature performance, poor cycle performance, and fast decay. These disadvantages of lithium manganese oxide come from the characteristics of manganese. However, due to the widespread presence of manganese, it has obvious cost advantages.

Lithium manganate ion battery refers to a battery with lithium manganate material used in the positive electrode. The nominal voltage of lithium manganate ion battery is 2.5~4.2v. Lithium manganate ion battery is widely used for its low cost and good safety.
