As aqueous rechargeable zinc batteries (ARZBs) edge closer to grid-scale deployment, the zinc metal anode remains dogged by dendrite proliferation and parasitic hydrogen evolution that slash cycle life and safety. Now, researchers from Zhejiang University, led by Prof. Yinzhu Jiang, have delivered a multiscale theoretical-experimental blueprint that deciphers and tames the electric double layer (EDL) at the zinc-electrolyte interface. The work, published in Nano-Micro Letters , introduces a low-cost sugar-derivative additive that rewrites interfacial chemistry, pushing Zn||Zn symmetric cells beyond 4 700 h and full cells to >90 % capacity retention after 800 cycles.
Why the EDL Matters
Innovative Multiscale Framework
Performance Breakthroughs
Future Outlook
The study establishes a transferable platform for additive-guided EDL engineering, opening a general pathway toward ultra-stable metal anodes beyond zinc.
