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
Common features are that the energy-storing processes take place at the phase boundary of the electrode/electrolyte interface, and electron and ion transport are separated [4]. Due to the fast-redox conversion on the surface, semiconducting conjugated polymers have considerable interest for electrochemical energy storage and conversion.
As a result, it is increasingly assuming a significant role in the realm of energy storage [4]. The performance of electrochemical energy storage devices is significantly influenced by the properties of key component materials, including separators, binders, and electrode materials.
