In this work, we highlight the performance recovery phenomenon when aging high-power lithium-ion batteries used in HEV application. This phenomenon consists in the increase on the battery capacity when we stop power-cycling. We demonstrate the dependency of this phenomenon on the stop-SOC value. Keeping battery at a fully discharged state potentially preserves a large amount of charge from the SEI-electrolyte interaction when they are in the positive electrode during rest time. Results from power cycling and combined, calendar/power cycling, aging of a 12 Ah-commercialized Lithium-ion battery at 55°C have been presented and obtained results have been discussed.
