主　　题：Supercapacitors Self-discharge Mechanism Suppressing strategy 

摘      要：Supercapacitors are one of the most promising energy storage devices in the fields of vehicle transportation,flexible electronic devices,aerospace,***,the existed self-discharge that is the spontaneous voltage decay after supercapacitors are fully charged,brings about the wide gap between experimental studies and practical utilization of *** eliminating the selfdischarge completely is not reachable,suppressing the self-discharge rate to the lowest point is possible and *** far,the significant endeavors have been devoted to achieve this ***,we summary and discuss the possible mechanisms for the self-discharge and the underlying influence ***,the strategies to suppress the self-discharge are systemically summed up by three independent but unified aspects:modifying the electrode,modulating the electrolyte and tuning the ***,the major challenges to suppress the self-discharge of supercapacitors are concluded and the promising strategies are also pointed out and *** review is presented with the view of serving as a guideline to suppress the self-discharge of supercapacitors and to across-the-board facilitate their widespread application.
