Capacity loss
Capacity fading in Li-ion batteries occurs by a multitude of stress factors, including ambient temperature, discharge C-rate, and state of charge (SOC). Capacity loss is strongly temperature-dependent, the aging rates increase with decreasing temperature below 25 °C, while above 25 °C aging is accelerated with increasing temperature. Capacity loss is C-rate sensitive and higher C-rates lead to a faster capacity loss on a per cycle. …
