Summary: Solid-state batteries (SSBs) are considered as advanced energy storage technology with higher safety and energy density. However, the solid-solid interface contact between ceramics electrolytes and Li anode leads to large interfacial resistance. Introducing a polymer-based coating, such as Poly(lithium 4-styrenesulfonate) (PLSS), can effectively solve this problem by providing fast Li+ ion transfer and blocking electron. PLSS-based cells demonstrate improved long-life cycling.

Summary: In this study, N-methylformamide (NMF) was introduced as an organic solvent and its solvation structure was modulated to obtain a stable organic/aqueous hybrid electrolyte for high-voltage Zn batteries. NMF showed excellent stability against Zn metal anodes and reduced the availability of free water molecules by creating numerous hydrogen bonds, allowing for the use of high-voltage Zn||LiMn2O4 batteries. The introduction of NMF prevented hydrogen evolution reaction and promoted the formation of an F-rich solid electrolyte interphase, thereby inhibiting dendrite growth on Zn anodes. The Zn||LiMn2O4 full cells exhibited a high average Coulombic efficiency of 99.7% over 400 cycles.
