This product is designed for researchers conducting electrochemical tests in organic three-electrode systems, particularly where larger electrode areas are required. The Three-electrode battery test mold 02, from Zhongke Wanyuan, accommodates conventional electrode dimensions ranging from 16 to 20 mm, making it suitable for studies on battery materials and electrolyte behavior. Its construction ensures stable and reproducible contact between electrodes, supporting accurate impedance, cyclic voltammetry, and charge-discharge measurements. Users must specify exact electrode dimensions when placing an order to ensure proper fit and reliable performance. This mold is a practical tool for academic and industrial labs focusing on advanced energy storage research, offering a robust solution for three-electrode cell assembly without the need for custom fixtures.
