Cathode materials for lithium ion batteries - Determination
of water content - Carl fisher coulomb method
1 Scope
This document describes the Karl Fischer Coulometry method for the determination of
water content in cathode materials for lithium-ion batteries.
This document is applicable to the determination of water content in positive electrode
materials such as lithium cobalt oxide (LCO), lithium nickel cobalt manganese oxide
(NCM), lithium nickel cobalt aluminum oxide (NCA), lithium manganese oxide (LMO),
lithium iron phosphate (LFP), and lithium ferromanganese phosphate (LMFP). The
determination range is 0.0005%~0.5000%.

3 Terms and definitions
The following terms and definitions apply to this document.
3.1 dew point temperature
The temperature at which the vapor pressure of water in a gas is equal to the saturated
vapor pressure of water at a certain temperature.
4 Principle
The sample is heated in a heating furnace, and the water in the sample evaporates into
water vapor, which is carried into the titration cup of the Karl Fischer moisture titrator
by dry carrier gas for measurement. The water in the sample reacts chemically with the
