Dendrite-free zinc metal anodes enabled by electrolyte additive for high-performing aqueous zinc-ion batteries

Abstract

Rechargeable aqueous Zn-ion batteries (ZIBs) have regarded as a preferable candidate for large-scale energy storage due to their high safety and the natural abundance of Zn. However, the zinc anode...

Recent progress in structural modification of polymer gel electrolytes for use in solid-state zinc-ion batteries

“…131,132 The ionic conductivity of the gel electrolyte is improved through the properties of these metal ions and good coordination with the gel main chain. 62,133 Simultaneously, the composited polymer gel shows good frost resistance and excellent physical properties, such as self-healing. 134,135 Because Zn 2+ is unconstrained and freely distributed in the electrolyte, lower nucleation sites near the surface of zinc foil preferentially deposit Zn 2+ , leading to the formation of protrusions.…”

Highly stable and reversible Zn anodes enabled by an electrolyte additive of sucrose

“…Therefore, reliable grid-scale energy storage devices are urgently required. 1–5 Considering the sheer scale of the demand, it is crucial to use earth-abundant elements. 5…”

Adjusting zinc deposition behaviors by a modified separator to acquire zinc anodes for aqueous rechargeable zinc-ion batteries

“…Because of the finite nature of traditional fossil fuels, wind power and solar energy have become the mainstream choices for sustainable energy sources. 1–3 Nevertheless, green and clean energies require massive energy storage devices that are safe and inexpensive to operate. Energy storage equipment-based electrochemical reactions such as those that occur in rechargeable batteries and supercapacitors are the easiest, most convenient, cleanest, and most extensively utilized for effective power storage and transmission.…”
