Advancements in Dendrite Suppression for Enhanced Energy Storage Technologies

Abstract

Aqueous zinc batteries have emerged as promising alternatives to conventional lithium-ion batteries, offering an environmentally friendly and cost-effective solution to our growing energy storage needs. However, one of the critical obstacles to realizing their full potential lies in addressing the dendritic structure growth challenges within zinc batteries. These dendrites, unwanted metal protrusions that form during the charging and discharging cycles, can lead to adverse implications, including short circuits, reduced battery performance, and safety concerns. To overcome these challenges, researchers and engineers have been diligently devising strategies. This paper delves into the complexities of dendrite formation in aqueous zinc batteries, outlining their adverse implications for battery performance and safety. Various strategies to address the dendrite challenge are explored, with a focus on their effectiveness and limitations. One promising avenue involves developing innovative three-dimensional (3D) structural designs within the battery architecture to inhibit dendrite formation. Conclusively, harnessing the potential of aqueous zinc batteries hinges on the successful mitigation of dendrite formation through the concerted implementation of ingenious 3D structural designs and other innovative strategies, steering the pathway towards safer and more efficient energy storage solutions.
