Self-discharge is an unwelcome phenomenon in electrochemical energy storage devices. Factors responsible for self-discharge in different rechargeable batteries is explored. Self-discharge in high-power devices such as supercapacitor and hybrid-ion capacitors are reviewed. Mathematical models of various self-discharge mechanisms are disclosed.
Further, the self-discharging behavior of different electrochemical energy storage systems, such as high-energy rechargeable batteries, high-power electrochemical capacitors, and hybrid-ion capacitors, are systematically evaluated with the support of various theoretical models developed to explain self-discharge mechanisms in these systems.
Identical kinetics and thermodynamics between corrosion of metals and self-discharge of batteries. a Only the irreversible type of self-discharge is considered. Therefore, the theory and methodology of Evans Diagram can be feasibly transplanted into self-discharge in rechargeable batteries.
Different self-discharge mechanisms are analyzed in detail and provide prospects to address the self-discharge in energy storage systems by giving directions to the various self-discharge suppression strategies, varying from diverse device components (electrode and electrolyte materials, separators, etc.) to cell assembling and protocols.
