The safe storage of electrical energy with high energy and power density is a challenge. Materials and process engineering aspects are in the foreground at Fraunhofer IFAM in order to develop solutions for electrical, chemical, and thermal energy storage systems. The focus is on Li-ion, solid-state, and metal/air batteries.
AFUE (Annual Fuel Utilization Efficiency is the "Ratio of heat output of the furnace or boiler compared to the total energy consumed by a furnace or boiler." (U.S. Dept. of Energy). AFUE of 90% means that 90% of the energy of the fuel becomes heat for the facility and the other 10% escapes up the chimney or elsewhere.
Moreover, the EVs demand both high energy and high power densities of the onboard energy storage system, but batteries have comparatively high energy density yet low power density. One effective solution to this issue is the adoption of hybrid energy storage systems (HESS) composed of battery and supercapacitor.
