Although high-voltage lithium battery materials are getting more and more attention, these high-voltage anode materials are still unable to achieve good results in practical production and application. The biggest limiting factor is that the electrochemical stability window of the carbonate-based electrolyte is low. When the battery voltage reaches about 4．5（vs．Li/Li＋）, the electrolyte begins to p...

The lithium-rich manganese-based (xLi[Li1/3-Mn2/3]O2; (1–x) LiMO2, M is a transition metal 0≤x≤1, and the structure is similar to LiCoO2) has a high discharge specific capacity. It is about twice the actual capacity of the cathode material currently used, and is therefore widely studied for lithium battery materials. In addition, since the material contains a large amount of Mn element, it is more...

The most widely used battery is still lithium battery, but lithium battery also has some problems that need to be improved. One of the key problems is that the lithium battery cathode produces excess oxygen, which reacts with the electrolyte and causes a thin film to form on the surface of the battery cathode, reducing energy transfer and thus the overall performance of the battery. To solve this ...
