SJ/T 11794-2022 《Test method for unbonded lithium of cathode materials used in lithium ion battery》 Related products

This document specifies the method for the determination of free lithium content in anode materials for lithium-ion batteries. It is suitable for the determination of free lithium content in anode materials such as nickel drill lithium manganate, nickel cobalt aluminate, lithium cobalt oxide, lithium manganate, nickel manganate, and lithium-rich manganese base. The principle of the method is to dissolve lithium carbonic acid and lithium hydroxide in the sample in distillation water, then filtrate, and finally use dilute muriatic acid solution as the titration solution to carry out automatic Potentiometric titration, poten-tiometry.
