Battery Production - Cell Finishing - Aging

Cell finishing is the final stage of battery production. These documents define the process:

• OPC 40753 – 1 Formation
• OPC 40753 – 2 Aging

This specification part describes the aging process step.
It denotes the process step in which battery cells are stored or treated under defined conditions after formation. It is used to evaluate and stabilize electrochemical behaviour, gas evolution, self-discharge, and reliability of the cells.
