Abstract Scope High-temperature liquid metal lithium batteries have always occupied a very important position in the field of energy storage. It has high energy storage efficiency and long life. However, high operating temperatures and low safety have been factors that have plagued the development of liquid metal lithium batteries. Here,we report a new chemistry of LiI-KI electrolyte and Bi-Sn positive electrode to lower the operation temperature of Li-based LMBs and achieve the long-term stability. We show that the assembled Li|| LiI-KI || Bi–Sn can stably cycle at an intermediate temperature less than 300 °C at current densities of 50 mA/cm-2 to 200 mA/cm−2 respectively with almost no capacity decay, and an average Coulombic efficiency of 97~98%. Our design provides new ideas for the development of energy storage.
