A sub-100 °C aluminum ion battery based on a ternary inorganic molten salt

By using a low-cost, ternary AlCl3/LiCl/KCl inorganic molten salt as the electrolyte, an aluminum ion battery is able to work stably below 100 °C. When intergrated with a graphite paper cathode, the battery exhibits close performance and similar electrochemical transformations to inorganic electrolyte-based batteries operating at ≥120 °C.
