Solvation structure regulation of an organic small molecule additive for dendrite-free aqueous zinc-ion batteries

Abstract

FA achieves uniform zinc deposition and better low temperature performance of AZIBs by participating in Zn2+ solvation structure, interaction with H2O in electrolyte, preferentially adsorping on Zn surface, and promoting the formation of SEI.

Rationally designed carbon-encapsulated manganese selenide composites from metal–organic frameworks for stable aqueous Zn–Mn batteries

“…They are poised to emerge as viable alternatives to commercial lithium-ion batteries (LIBs) in applications such as large-scale energy storage and 3C electronics. Recent advancements in AZIBs primarily target two key challenges: (1) mitigating issues like zinc dendrite formation, corrosion, and other side reactions at the anode, [3][4][5][6][7][8] and (2) identifying a suitable cathode material to serve as the primary carrier for zinc ions. [9][10][11][12] Among the various cathode materials explored for AZIBs, manganese-based compounds emerge as promising contenders due to their high potential (approximately 1.8 V), substantial theoretical capacity (e.g., manganese dioxide boasting 308 mA h g −1 ), costeffectiveness, and ease of preparation.…”
