Battery Production - Cell Finishing - Formation

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 formation process step.
It denotes the initial electrochemical activation process of a newly assembled battery cell. It consists of controlled charging and discharging cycles that form boundary layers inside the cell and establish the conditions required for stable ion transfer.
