|description===Production process==

*Aging represents the final step in cell production and is used for quality assurance.
*During aging, cell characteristics and cell performance are monitored by regularly measuring the open circuit voltage (OCV) of the cell over a period of up to three weeks.
*A distinction is made between high temperature (HT) and normal temperature (NT) aging. The cells usually first undergo HT aging and then NT aging.
*The cells are stored in so-called aging shelves and/or towers.
*No significant change in the cell properties over the entire period of time means that the cell is fully functional and can be delivered to the customer.
*In contrast to formation, the pouch cells are no longer pressurised in this process step.
*The duration of the aging process depends strongly on the respective cell manufacturer and the cell chemistry used.

==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==

*There are different procedures for the sequence and duration of HT and NT aging depending on the cell manufacturer and cell chemistry.

==Quality influences==

*Orientation of cells
*Packing density of the cell good carriers
*Ambient temperature

==Quality features==

*Capacity
*Internal resistance
*Self-discharge rate
