Why Determine the Total Metal Content in NMC Cathode Material?

Determining the total metal content of NMC cathode material is significant for both quality control and research on cathode material as the relative composition of Ni, Mn, and Co is relevant for battery performance.

What Is the Structure of NMC Cathode Material?

The general structure of NMC cathode material is described as LiaNixMnyCozO2, where the relative contents of nickel, manganese, and cobalt (x, y, and z) are crucial for battery performance.

How to Prepare the Sample?

The sample preparation method includes dissolving the sample in hydrochloric acid, evaporating the water until the sample is dry, adding a pH 10 buffer, and using a murexide indicator for titration.
