摘要

The development of sustainable energy is an effective way to solve the world energy shortage problem.Energy storage is of critical importance to the grid-scale utilization of renewable energy sources.Among various energy storage techniques, electrochemical energy storage, namely secondary batteries have attracted significant attention owing to the prevalence of electronic products such as electric vehicles and mobile devices.Lithium-ion battery is currently the most widely used battery.However, the specific energy of lithium-ion batteries (＜250 Wh/kg) no longer meets the increasing demand.Therefore, novel batteries system beyond Li-ion battery need to be pursued to meet the requirement of high specific energy.
