Research and progress of liquid metal battery system

With the acceleration of the transformation of the global energy structure to renewable energy, large-scale energy storage technology has become a key way to solve the grid-connected stability of intermittent renewable energy, such as wind power and photovoltaic. As a high-efficiency electrochemical energy storage device, batteries are crucial for the effective utilization of intermittent renewable energy. Liquid metal batteries have shown broad application prospects due to their outstanding advantages, such as long life, low cost, and high safety. This paper expounds the basic principle of LMB, especially the selection of electrode materials, and presents several typical electrode materials in the Liquid metal battery (LMB) system. The development direction of battery materials in the future is projected.
