The introduction of low-cost, low-reduction-potential Na+into aqueous Zn-based battery electrolytes suppresses Zn2+aggregation at the anode interface through preferential Na+adsorption and inter-cationic electrostatic repulsion, thereby enabling homogeneous Zn deposition and significantly enhanced low-temperature reversibility of Zn anodes.Na+with low ionic potential spontaneously adsorbs at the anode–electrolyte interface, effectively reducing solvated water molecules and suppressing parasitic Credit: Guanchong Mao, Pan Xu, Xin Liu*, Xingyu Zhao, Zexiang Shen, Dongliang Chao, Minghua Chen*.

As renewable energy storage demand grows, the limitations of aqueous zinc metal batteries (AZMBs) in subzero environments become more pronounced. Now, researchers from Harbin University of Science and Technology and Fudan University, led by Professor Xin Liu and Professor Dongliang Chao, have presented a breakthrough solution using trace Na 2 SO 4 as an electrolyte additive. This work offers valuable insights into developing next-generation energy storage technologies that can overcome low-temperature challenges.
