Introduction: In combination with the high-precision pressure control, thickness and resistance testing system, the two-plane controllable pressure disc electrode resistance method is used to test the overall penetration internal resistance of the electrode piece, including the sum of the coating resistance, the contact resistance between the coating and the fluid collector, and the fluid collector resistance, which is used for the formulation development of the electrode piece and the process stability monitoring.

Application: material evaluation, process evaluation, cell failure analysis
