ECCS B320
The ECCS B320 is an electro-chemical reaction visualizing confocal system that enables operand observation of lithium-ion batteries. It observes the electrode cross-section in real-time during charge/discharge cycles and visualizes the internal reactions of the battery.
With the real-color confocal optical system, it can observe color changes in electrode materials with high precision, providing important information for battery performance evaluation and research and development.
