Aging and Safety in Cylindrical Cells


Aging and Safety in Cylindrical Cells

Aging due to cycle life refers to all the degradation processes associated with the charge and discharge processes. Every time a Li-ion cell is cycled, its capacity reduces in an imperceptible way. In the long-term cycling, the cell loses a significant amount of its initial capacity. The rate of capacity loss depends upon multiple factors like operating temperature, cycling protocol, C-rate, and the charge/ discharge cut-off voltages. Determining the actual state of health of the cells after cycling is essential for recycling or repurposing them in secondary-use applications.


Cycle life aging data for cylindrical cells and modules. 
The 18650 cell has graphite as anode and nickel-cobalt-aluminum oxide (NCA) as cathode active materials.
Module has a 3P9S (3 cells in parallel (bank), 9 banks in series) configuration.
