This proposal addresses a major problem of energy storage : increasing the volumetric energy density of supercapacitors. These systems are increasingly used in applications related to transportation with the main issues to increase their energy density by volume while maintaining their power density and durability. To reach this goal, it is proposed to replace the conventional carbon electrodes ( 7Wh/L) with denser materials such as metal oxides. The performance of a prototype based on two oxide based electrodes (Fe3O4 and MnO2 ) will be evaluated while developing new materials and new architectures that can meet the criteria of energy density (>10Wh/L), power (>5 kW/L) and durability (> 100,000 cycles), with improved safety since these materials can be operated in aqueous instead of organic electrolytes.
