Abstract:Energy storage technology plays a central role in renewable energy integration, microgrid, power grid peaking and efficiency improvement, regional energy supply, electric vehicles and other applications. It is vital to solve issues of energy resources and energy security, to implement energy conservation and emission reduction, and to promote a green and low carbon world. The strategic need for carbon development has played a key role in the energy revolution. This article mainly introduces electrochemical energy storage technologies with important market prospects, including flow batteries, lithium-ion batteries, lead-carbon batteries, and sodium-based battery technologies. Based on the analysis of the development status of electrochemical energy storage technologies, China's future development strategy is elaborated in the paper as well.
