Reconfiguring solvation network and interfacial engineering of Zn metal anode with biomass carbon quantum dot.

The implementation of aqueous zinc-ion batteries (AZIBs) in energy storage systems has uneven Zn dendrites and side reactions seriously at the zinc anode and electrolyte interface. A novel green biomass carbon quantum dot (BCDs) additive influenced the hydrogen bonding network of the electrolyte, reduced water activity, and suppressed hydrogen evolution corrosion of the zinc anode. At the same time, we proposed a buffer redistribution effect that BCDs can act as the support of SO, and the linkage mechanism can further prolong the residence time of Zn on SO-BCDs.

Succinonitrile Electrolyte Additive for Stabilizing Aqueous Zinc Metal Batteries.

The utilization of water electrolytes in zinc-ion batteries offers the advantages of enhanced safety, reduced cost, and improved environmental friendliness, rendering them an optimal choice for replacing lithium-ion batteries. Nevertheless, the conventional zinc sulfate electrolyte fails to meet stringent requirements. Therefore, developing electrolytes is crucial for addressing the low cycle life of zinc ions and suppressing the growth of zinc dendrites.
