Si Anode

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...
