SASPE – Subduing Self-discharge of All-solid-state supercapacitors by a novel hybrid Solid Polymer Electrolyte with layered inorganic nanofiller

Hybrid supercapacitors, which combine both batteries and supercapacitors in one physical unit, hold great potential for powering electric vehicles and microgrids. Despite demonstrating superior specific power and cycle life over conventional batteries, the high self-discharge rates, high production costs and safety concerns impede their market uptake. The EU-funded SASPE project aims to develop a solid-state supercapacitor that will be more efficient and cost-effective. Notably, SASPE will introduce a solid polymer electrolyte with high ionic conductivity to reduce the self-discharge rate. Furthermore, researchers will develop electrodes with promising electrochemical performance such as high specific capacitance, energy density and power density.
