Problems solved by technology

[0004] Although lithium / manganese dioxide flexible packaging batteries have been researched in China, the problems in storage performance, high temperature performance, environmental adaptability and low temperature performance of the battery have not been solved so far, and there are still many technical key points that need to be broken through.
Therefore, lithium / manganese dioxide flexible packaging batteries still cannot meet the requirements of many applications
The key reason is that the high-performance manganese dioxide positive electrode material and the corresponding positive electrode sheet preparation and the overall comprehensive design of the battery have not been developed.
