Summary: Water-in-salt electrolytes have made aqueous Li-ion batteries one of the most promising candidates for overcoming safety issues in traditional Li-ion batteries. By increasing the Li-salt concentration in the electrolytes, the electrochemical stability window of aqueous electrolytes can be expanded beyond 2 V. However, improving stability requires more complex ternary electrolytes. In this study, the effects of novel Gemini-type ionic liquids (GILs) as co-solvent systems in aqueous Li[TFSI] mixtures were explored, and their transport properties and electrochemical performance were investigated. Devices containing pyrrolidinium-based GILs showed superior cycling stability and promising specific capacity in cells using commonly used electrode materials LTO (Li4Ti5O12) and LMO (LiMn2O4).

Summary: Organic batteries using redox-active polymers and small organic compounds are promising for next-generation energy storage devices due to their abundance, environmental benignity, and diverse nature of organic resources. However, the correlation between electrolyte structure and battery performance has received less attention. This review discusses the prospects and challenges of organic batteries, with a focus on electrolytes. The differences between organic and inorganic batteries in terms of electrolyte requirements and charge storage mechanisms are elucidated, and different types of electrolytes and their components, concentrations, additives, and applications in organic batteries are introduced.

Summary: To address low Coulombic efficiency and premature failure in Zn metal batteries, an integrated eutectic electrolyte was used to construct a gradient organic/inorganic hybrid SEI layer on the Zn anode. This layer with a gradient structure and composition alleviates corrosion and passivation on the Zn anode, as well as inhibits dendrite growth. The results show a significantly improved Coulombic efficiency of 99.8% over 1200 cycles and a high cumulative plated capacity of 5.57 A h cm(-2) at 5 mA cm(-2).

Summary: Low-temperature-tolerant and durable Zn-ion hybrid supercapacitors (ZHSCs) were fabricated by modulating a co-solvent water/ethylene glycol electrolyte. The electrolyte with ZnSO4/water/ethylene glycol (65%) composition showed high ionic conductivity at low temperatures and effectively prevented dendrite formation in the Zn anode. These ZHSCs demonstrated long-term cyclability and operation at sub-zero temperatures as low as -40 degrees C, making them potentially valuable in next-generation electrochemical energy storage devices.
