This standard specifies a method for the determination of the amount of cobalt in lithium cobalt oxide, a lithium ion battery anode material. It is applicable to lithium cobalt oxide with cobalt content ranging from 58.00% to 62.00%. The method uses the EDTA Titrimetric method to dissolve the sample through muriatic acid and use violet uric acid amine as an indicator in alkaline solution. During titration, the EDTA standard solution reacts with cobalt until the solution changes from orange to purple as the end point. The cobalt content is calculated based on the volume of EDTA standard solution consumed. This method ensures the accurate determination of cobalt content and is suitable for the quality control of battery anode materials.
