Abstract
A method for detecting a surface coating performance of a cathode active material comprising: providing an acid solution with a predetermined concentration; putting a coated cathode active material in a container; adding the acid solution into the container until the coated cathode active material is completely soaked to form a solid liquid mixture; sealing the container, heating and stirring the solid liquid mixture, and recording a series of pH values of a liquid phase of the solid liquid mixture at different points in time; and determining the surface coating performance of the coated cathode active material by comparing the recorded pH values with standard pH values. A method for detecting a surface coating performance of a cathode active material by detecting metal ion concentrations in the solid liquid mixture is also provided.
