Battery Formation
Battery formation is the initial charging and discharging process after cell assembly. During formation, a stable Solid Electrolyte Interphase (SEI) layer is created on the electrode surface, which is essential for battery performance and long-term stability.
Battery Grading
Battery grading classifies cells according to key performance parameters such as:
Capacity
Internal Resistance (IR)
Voltage
Energy Efficiency
Self-Discharge Rate
The grading process ensures that only cells with similar characteristics are grouped together for battery pack assembly, improving overall pack consistency and safety.
