Conclusions The discharge capacities of lithium ion cells were recovered by using recovery electrodes and replenishing positive or negative electrodes with Li+. Discharge curve analysis revealed that capacity recovery was possible due to recovery from capacity slippage between the positive and the negative electrodes.
