This Special Issue series focus on the latest and cutting-edge advances in field closely related to “energy storage and conversion” and discuss the needs as well as priorities currently exist or the trends in this field over the next few decades. It pays close attention to the core topics but not limited to, the following:

• Theoriesand applications of energy storage and conversion;
• Power electronics and converters for electrical vehicles;
• Electrical Engineering for smart grids, microgrids, etc.;
• Devicesfor renewable energies, e.g. solar, wind, hydro and marine power;
• HVDC and conversion systems;
• Technologies, processes, materials, testingand modelingof batteries;
• Fuel cells and hydrogen-based systems;
• Supercapacitors (ultracapacitors) and lithium-ion capacitors;
• SMES;
• Management systems, such as BMS;
• Energy harvesting and recovery
