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.
Dendrite
ECCS B320 shows dendrites being formed while a battery is overcharged at high rate. Once the charging stops, the dendrites start to shrink and lithium ions are dispersed from dendrites to charge the anode.
