On December 4, 2025, a research group from Tianjin University shared their research results in the renowned international journal Nature Sustainability. They successfully formulated a low-corrosive "organic dichloro" electrolyte, which offers a fresh approach for the widespread adoption of aluminum metal batteries. Aluminum metal batteries are considered an extremely promising energy storage technology. This is attributed to the high theoretical specific capacity of aluminum anodes, their cost-effectiveness, and the characteristic of three-electron transfer. Nevertheless, conventional electrolytes are plagued by problems like high corrosiveness and excessive viscosity. These issues cause the rapid deterioration of battery metal parts and impede their real-world application. The newly created electrolyte substantially diminishes corrosiveness and boosts electrochemical reversibility. This is achieved by precisely controlling the solvation structure to keep corrosive chloride ions in close proximity to aluminum ions. This innovation marks a vital step forward for the practical utilization of aluminum metal batteries.
