Self-discharge in rechargeable electrochemical energy storage

Self-discharge (SD) is a spontaneous loss of energy from a charged storage device without connecting to the external circuit. This inbuilt energy loss, due to the flow of charge driven by the pseudo force, is on account of various self-discharging mechanisms that shift the storage system from a higher-charged free energy state to a lower free state (Fig. 1 a) [32],
