What Is NMC?

Cathode materials in lithium-ion batteries are compounds consisting of the chemical elements nickel, manganese, and cobalt. Hence they are commonly referred to as the NMC cathode. This cathode material is particularly suitable for electric vehicles due to the combination of high energy density and relatively low price.

 

Why Determine NMC Content in the Cathode?

The relative composition of NMC cathode materials proves to be relevant for the battery performance. Hence the determination of nickel, manganese, and cobalt is important for quality control and research.

 

How to Determine NMC Content in the Cathode?

The total and individual metal content of NMC cathode material can be determined according to the Chinese standard YST 1006.1-2004 by complexometric titration using a copper ion selective electrode as the indicating sensor. This titration method involves both direct and back-titration techniques.
