Abstract

A method of determining ageing of a mixed electrode of a full cell lithium ion battery is presented. The method includes obtaining a voltage hysteresis of the full cell lithium ion battery by comparison of a charging voltage to a discharging voltage at a specific state of charge, SOC. The specific SOC is in a range from 0% to 20% of a maximum SOC. The method further includes determining ageing of a volume expanding component of the mixed electrode based on the obtained voltage hysteresis.
