Electrode Plate Resistance Tester

The Electrode Plate Resistance Tester integrates high-precision pressure control with thickness and resistance measurement systems. It uses a dual-plane controllable pressure disc electrode method to test the overall through-plane internal resistance of electrode plates, including coating resistance, contact resistance between coating and current collector, and current collector resistance. This device is suitable for electrode formulation development and process stability monitoring.
