Application Note on the pH Measurement of Cathode Material Using the Right Sensor

pH measurement of battery cathode material
pH measurement of battery cathode material

Measuring the pH of cathode material can offer several challenges. The nature of slurry and particulate matter present pose difficulties in measuring pH using a traditional laboratory pH sensor. Poor reproducibility, fluctuating readings, and slower response times are some of the challenges.

The use of a specialist sensor like InLab® Max Pro-ISM, is the right choice for measuring the pH of cathode materials of lithium-ion batteries. The chemically resistant glass membrane of this sensor makes it a preferred choice while measuring the pH of organic solvents or while analyzing other harsh chemicals. Thanks to its immovable sleeve junction, the sensor is easy to clean. These, along with a few more advantages listed in the application note, make the InLab Max Pro-ISM the correct sensor for the analysis of challenging samples like cathode materials of Li-ion batteries.

Frequently Asked Questions: Measuring the pH of Battery Cathode Material

 

What are the challenges associated with measuring the pH of cathode material in the case of Li-ion battery electrolytes?

The presence of particulate matter and the viscous nature of the slurry make it difficult for a traditional sensor to measure pH accurately using a traditional sensor. Some of the commonly encountered challenges are unstable readings, poor reproducibility, and longer response times.

 

What are the benefits of using an InLab Pro-ISM pH sensor while measuring the pH of cathode material for Li-ion batteries?

The InLab® Max Pro-ISM has a chemically resistant glass membrane, making it a preferred choice while measuring pH in challenging environments. The immovable sleeve junction allows a constant flow of the electrolyte even with difficult samples. This results in stable readings and a quick response time.
