Advantages and disadvantages of lithium manganate battery

Lithium manganate battery is a kind of battery which uses lithium manganate as cathode material. Its nominal voltage is between 2.5 V and 4.2V. It is widely used for its low cost and good safety.

The advantages of lithium manganate battery are good rate performance, easy preparation and low cost. The disadvantage is that the dissolution of manganese leads to poor high-temperature performance and cycle performance. By doping aluminum and sintering granulation, the high-temperature performance and circulation performance are greatly improved, which can basically meet the actual use. Generally speaking, the lithium-ion battery has low cost, strong stability, strong low-temperature performance, poor high-temperature performance, and slightly fast decay.

The application system of lithium-ion battery still takes plug-in hybrid as an important application field. What can not be ignored is that there are 36 pure electric bus models with lithium manganate as the important application, accounting for 17% of the matching models of lithium manganese dioxide. In addition, Zhongtong, Yutong, Yangzijiang, Ankai, Shenlong, Yaxing, etc. have all started to apply lithium manganate in pure electric bus models.
