Electrochemical Compatibility between Natural Graphite and Li6BaLa2Ta2O12 or Organic Electrolytes
The electrochemical compatibility between natural graphite and garnet-like Li6BaLa2Ta2O12 or organic electrolytes was investigated. The formation of solid electrolyte interface (SEI) films in the initial cycle was investigated by galvanostatic charge and discharge, cyclic voltammetry experiments. The experimental results show that electrochemical compatibility between natural graphite and Li6BaLa2Ta2O12 is the most excellent, while electrochemical compatibility between natural graphite and PC-based electrolytes are the poorest. In the initial cycle, the discharge capacity and charge-discharge efficiency are both the highest in Li6BaLa2Ta2O12 electrolyte, and they are 337.1 mAhg-1 and 99.5 %, respectively.
