天大开发“有机双氯”电解液 推动铝电池向大规模实际应用迈进

Core Viewpoint - The development of renewable energy and efficient utilization is essential for achieving "dual carbon" goals, with safe and green large-scale energy storage technology being a key support [1][2] Group 1: Research Breakthrough - A new low-corrosive "organic dichloride" electrolyte has been developed by a team led by Professor Yang Quanhong from Tianjin University, addressing a significant barrier for the large-scale application of aluminum metal batteries [1] - Aluminum metal batteries exhibit great potential due to their high theoretical specific capacity, abundant crustal reserves, and low cost, but their practical application has been limited by the electrolyte system [1][2] Group 2: Technical Innovations - The team proposed an innovative design strategy for the "organic dichloride" solvated electrolyte, replacing traditional ionic liquids with aluminum chloride or propylene oxide organic systems, significantly reducing the overall corrosiveness of the electrolyte [1][2] - This unique structure confines all corrosive chloride ions (Cl-) around aluminum ions (Al3+), ensuring stable and efficient charging and discharging cycles for aluminum batteries [1] Group 3: Industry Implications - This breakthrough not only resolves the strong corrosiveness issue faced by aluminum metal batteries but also opens a new electrochemical reaction pathway based on cationic active species, providing a fresh solution to common technical bottlenecks in aluminum and other multivalent metal batteries [2] - The research was a collaboration between the Tianjin University team and the Shenzhen Institutes of Advanced Technology, indicating a strong partnership in advancing energy storage technologies [2]
