Aqueous Zinc-Ion Batteries
Research Guide
What is Aqueous Zinc-Ion Batteries?
Aqueous Zinc-Ion Batteries (AZIBs) are rechargeable energy storage devices using zinc anodes and mild aqueous electrolytes as safe, low-cost alternatives to lithium-ion batteries.
AZIBs feature high safety from non-flammable electrolytes and abundant zinc resources. Research targets cathode materials like manganese dioxide and vanadates for improved cycling stability. Over 10 key papers since 2017 have amassed more than 12,000 citations, including Zhang et al. (2017, 1718 citations) on zinc-manganese dioxide systems.
Why It Matters
AZIBs enable safe grid-scale storage for renewables, addressing lithium scarcity and fire risks in lithium-ion batteries (Zhang et al., 2017; Wan et al., 2018). Full-cell prototypes achieve energy densities over 100 Wh/kg for stationary applications (Xia et al., 2017). They support sustainable energy transition with recyclable components and low-cost production (Jia et al., 2020; Li et al., 2019).
Key Research Challenges
Zinc Anode Dendrite Growth
Zinc anodes form dendrites during plating/stripping, causing short circuits and capacity fade (Du et al., 2020). Surface nonuniformity exacerbates irreversibility in aqueous electrolytes (Zhou et al., 2021). Strategies like crystal plane engineering mitigate this (Zhou et al., 2021).
Cathode Dissolution Issues
Manganese dioxide cathodes suffer phase changes and Mn2+ dissolution, limiting cycle life (Huang et al., 2018). Vanadate cathodes face structural instability during Zn2+ insertion (Wan et al., 2018). Intercalation stabilizers like polyaniline improve retention (Huang et al., 2018).
Electrolyte Corrosion Effects
Aqueous electrolytes promote hydrogen evolution and zinc corrosion, reducing Coulombic efficiency. Cation solvation modulation forms protective interphases (Qiu et al., 2019). Balancing pH and additives remains critical for longevity.
