pH Measurement of Cathode Material and the Performance Impact on Li-Ion Batteries

Mettler-Toledo GmbH

Quality Parameter in Battery Production: The pH Value of Cathode Material

Every component of a Li-Ion battery contributes to its efficiency. For this reason, qualitative raw material control is critical. The pH of active cathode materials such as carbon black has a direct influence on particle size distribution. The pH measurement of various active cathode materials is described and recommended in ASTM and ISO standards. Due to the sample matrix, these measurements can be challenging. All proven tips and hints regarding the correct sensor selection and handling can be found in our new application note for pH measurement in active cathode material.
