Abstract
The present disclosure provides a polymer solid electrolyte comprising a high molecular polymer and a lithiated carbon dot, wherein the lithiated carbon dot is obtained by lithiating a carbon dot with lithium hydroxide. The present application also provides a method for preparing a lithiated carbon dot and a method for preparing a polymer solid electrolyte. In the polymer solid electrolyte provided in the present application, the lithiated carbon dot is used as lithium salts, and the introduction of the lithiated carbon dot effectively reduces the crystal phase of the polymer matrix in the electrolyte, and significantly improves the electrochemical properties such as the ionic conductivity and ionic mobility of the polymer solid electrolyte.
