Electrochemical energy storage-storage-discharge loss
Self-discharge is a critical phenomenon in energy storage devices, where the stored energy is lost over time due to internal chemical reactions. This process affects the performance, lifespan, and overall efficiency of energy storage systems. The system converts the stored chemical energy into electric energy in discharging process. . 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. [pdf]
