Applications
Applications
- With the expansion force test fixture or in-situ expansion test equipment, the stress distribution at different positions on the surface of the cell during the cycling process is characterized.
- Quickly and quantitatively evaluate the surface flatnessof the cell.
Case 1. Test of stress distribution on the surface of the cell during the cycle
- Test information: NCM-Graphite system,3~4.3V, 0.5C, 50kg preload;
- Result analysis: It can quantitatively characterize the difference of stress distribution on the surface of the cell, provide a deeper perspective for the stress analysis of the cell, and help technicians analyze the stress distribution in the cell, explore the causes of failure of the cell and develop a safer and more reliable cell.
Case 2. Surface flatness test of fresh cell
- Result analysis: there is a certain correlation between the cell process design and the cell pressure distribution(flatness). Technicians can develop appropriate distribution standards through the pressure distribution system to monitor the batch stability of the delivered cells.
