Patent pre-warning analysis of cathode material for sodium ion battery
As a key material of sodium ion battery,cathode material of sodium ion battery has im-portant research value for electrochemical energy storage.This paper first analyzes the application tendency and technical themes of global patents of cathode material for sodium ion battery,and then focuses on the analysis of the patent information of the two major technical branches of tran-sition metal oxides and polyanionic compounds,and provides pre-warning analysis of the problems existing in the patent application of cathode materials from the perspective of patent infringement.And conclusions and suggestions are given in order to avoid the risk of intellectual property and improve the application and protection of independent intellectual property.
