Zinc Anode
Research Guide
What is Zinc Anode?
Zinc anode research develops strategies to mitigate dendrite formation, hydrogen evolution, passivation, and corrosion in aqueous zinc-ion batteries.
Studies focus on alloying, coatings, 3D hosts, and gel electrolytes for reversible zinc plating/stripping. Key reviews include Jia et al. (2020, Chemical Reviews, 1635 citations) on active materials and Du et al. (2020, Energy & Environmental Science, 1009 citations) on anode design challenges. Over 10 high-citation papers from 2011-2020 address these issues.
Why It Matters
Stable zinc anodes enable commercialization of low-cost, safe aqueous zinc-ion batteries for grid storage and EVs. Zhang et al. (2014, Advanced Energy Materials, 1303 citations) demonstrated a zinc/zinc hexacyanoferrate system exceeding 1.5 V voltage. Du et al. (2020) highlight structural designs achieving high performance, while Zhang et al. (2020, Angewandte Chemie, 1129 citations) show interfacial coatings suppress dendrites for long cycling.
Key Research Challenges
Dendrite Formation
Uneven zinc deposition creates dendrites piercing separators and causing short circuits. Zhang et al. (2020, Angewandte Chemie, 1129 citations) review interfacial designs to achieve dendrite-free plating. Du et al. (2020, Energy & Environmental Science, 1009 citations) discuss material strategies for uniform deposition.
Hydrogen Evolution
Water reduction at anode generates gas, reducing Coulombic efficiency. Xu et al. (2011, Angewandte Chemie, 1929 citations) note this limits zinc battery viability. Coatings and alloying in Jia et al. (2020, Chemical Reviews, 1635 citations) mitigate HER.
Passivation and Corrosion
ZnO/Zn(OH)2 layers block active zinc, causing capacity fade. Du et al. (2020) outline structural hosts to prevent passivation. Li et al. (2019, Nano Energy, 1117 citations) survey corrosion in zinc-based batteries.
