Scope

GB/T 37202-2018 is the English-translated version of 镍锰酸锂.

GB/T 37202-2018 is the Chinese national product standard for lithium nickel manganese oxide used as a cathode material in lithium-ion batteries.

It sets the requirements, starting with chemical composition, together with the test methods, the inspection rules, marking, packaging, transport and storage, the quality certificate and the content of the order form or contract.

The test methods it calls on include pH of the aqueous suspension, tap density, sampling, moisture content by the Karl Fischer method, specific surface area, laser diffraction particle size distribution and electrochemical tests for first discharge specific capacity, first charge and discharge efficiency, discharge platform capacity ratio and cycle life, with the JCPDS 80-2162 X-ray powder diffraction reference pattern.

Terms are taken from GB/T 20252-2014 on lithium cobalt oxide. It was issued on 28 December 2018 and has applied since 1 November 2019.
