This standard specifies the test method for the specific capacity of lithium cobalt oxide for first discharge and the efficiency of first charge and discharge of lithium ion battery anode materials. It is applicable to determine the battery performance of lithium cobalt oxide at the time of initial use, including the specific capacity and efficiency of its charge and discharge. The required reagents and materials, such as lithium hexafluorophosphoric acid and carbonic acid ester solvent, are enumerated in the standard to ensure the accuracy of the test. These tests provide basic data for evaluating the initial performance of lithium cobalt oxide materials and optimizing battery design.
