Improving the performance of a SnS₂ cathode with interspace layer engineering using a Na⁺ insertion/extraction method for aqueous zinc ion batteries

Abstract

Na ion insertion/extraction in a layered structure of SnS2 leads to considerably high interspace layers SnS2 (SnS2-HIL) from 0.86 to 1.10 nm. It enables higher Zn2+ storage capacity in SnS2-HIL cathodes.

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

“…Recent advancements in AZIBs primarily target two key challenges: (1) mitigating issues like zinc dendrite formation, corrosion, and other side reactions at the anode, 3–8 and (2) identifying a suitable cathode material to serve as the primary carrier for zinc ions. 9–12 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 ), cost-effectiveness, and ease of preparation.…”
