Energy storage technology is a critical support for efficiently integrating large-scale renewable energy and constructing new types of power systems. The urgent demand for low-cost, long-life, high-safety medium-to-long duration energy storage technologies becomes increasingly prominent as the proportion of renewable energy connected to the grid rises. Among these, electrochemical energy storage stands out for its flexibility and efficiency, rapidly developing into a strategic focus supported by China and a global competition hotspot in emerging industries.
To meet the significant demands of large-scale energy storage applications, the project team, based at the Advanced Electrical Materials and Devices Research Center of the National Key Laboratory of Strong Electromagnetic Engineering Technology, undertook this challenge with strong support from national key R&D programs and the National Natural Science Foundation of China. Through close collaboration between university and industry, after more than a decade of relentless effort, the team has broken through traditional electrochemical energy storage principles and architectures, invented new materials and systems for liquid metal storage batteries, and overcame key challenges in interface stability control and long-term service characteristics regulation for large-capacity liquid metal batteries. As a result, they have successfully developed China's first 5kW/30kWh liquid metal battery energy storage demonstration system, achieving technical indicators that lead internationally. This advancement paves the way for the development of liquid metal battery storage technology, providing an important low-cost, long-life, high-safety medium-to-long duration energy storage solution for new power systems.
