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.

Applications

(1)Material evaluation

(2)Process evaluation

(3)Battery cell failure analysis

Main Features

(1)Innovative electrode resistance testing method for evaluating the uniformity of the conductive network in electrode plates.

(2)Fully automated testing software with freely adjustable parameters and one-click start.

(3)Real-time monitoring and output of pressure, compressive stress, environmental temperature, environmental humidity, thickness, resistance, resistivity, conductivity, and compaction density, with automatic data saving.

(4)Equipped with standard thickness blocks and resistance blocks calibrated by a third-party metrology institute.

Key Advantages

(1)Directly measures the true through-plane resistance of electrode plates.

(2)Separates voltage and current lines to eliminate inductive effects on voltage measurements, improving accuracy.

(3)Equipped with standard resistance and thickness blocks calibrated by a third-party metrology institute.

Technical Parameters

Testing Method and Principle

The BER series multifunctional Electrode Plate Resistance Tester uses a dual-plane controllable pressure disc electrode method to directly measure the true overall through-plane resistivity of electrode plates, which includes coating resistance, contact resistance between coating and current collector, and current collector resistance.
