The key to the core of lithium manganate battery is the raw material and synthesis method

　　The structure and performance of lithium manganate cathode materials are not only closely related to the raw materials and the calcination process conditions, but the electrochemical performance of the materials prepared under different synthesis conditions (raw materials, temperature, calcination time and process lamps) is very different, and is also very different from Doping elements and doping amount are related, and the cycle attenuation is fast-especially at high temperatures, the attenuation is more obvious. Therefore, choosing raw materials and improving the synthesis method of materials is the key.

　　In terms of raw materials, Keda Weilong uses layered lithium manganate, which has high discharge specific capacity and cycle performance, and also has good rate and high temperature cycle stability. From the perspective of raw material selection, the overall cost-effectiveness is higher. .

　　In terms of the synthesis method, Keda Weilong uses a low-temperature calcination semi-wet method for the synthesis process and composition of conventional lithium manganate materials, and improves the cathode performance of lithium manganate by doping other elements, which significantly reduces the synthesis temperature and time. Obviously shortened, but because of the confidentiality of the process involved, it can not be described in detail.

　　Earlier, some media broke that Tesla is planning to use graphene batteries, which only need 8 minutes to charge and can travel 1,000 kilometers. Wang Meng told Chuangyebang that graphene cannot be used as the main material of the battery and can only be used as a small amount of auxiliary material.
