The self-discharge losses in several lithium-ion cell designs have been measured by three different methods. The losses are separated into time-dependent and state-of-charge dependent contributions. For most cycling conditions, the time-dependent self-discharge losses are dominant; however, after several months of stand on open circuit or float charge, the state-of-charge dependent losses become significant. The self-discharge rate has been found to not increase monotonically with state-of… Expand
