Description
Production process
- Final step in cell production
- Process aims at for quality assurance
- Cell characteristics performance are monitored over a period of up to three weeks: Regular measurment of open circuit voltage (OCV)
- Aging differentiation: High temperature (HT) and normal temperature (NT) aging; usual againg sequence: first, HT aging and, then, NT aging
- Storage in so-called aging shelves and/or towers
- Quality assurance: No significant change in the cell properties over the entire period of time
- Aging duration depends strongly on cell manufacturer and used chemistry
Process parameters & requirements
- State of charge of the cell at the beginning of aging: 80 % - 100 % SOC
- Aging time: up to 3 weeks
- Normal temperature approx. 22°C, high temperature approx. 30°C - 50°C
Technology alternatives
- Different procedures for sequence and duration of HT and NT aging (depending on cell manufacturer chemistry).
Quality influences
- Orientation of cells
- Packing density of the cell good carriers
- Ambient temperature
Quality features
- Capacity
- Internal resistance
- Self-discharge rate
