“…Operating with WiS liquid electrolytes, ZM DIB devices still require suitable separators, preventing direct electrical contact and short circuits within the battery. Glass-fiber (GF) separators are commonly selected for aqueous-based batteries, yet they face challenges such as the electrolyte leakage risk, zinc dendrite penetration, and limitations in durability and flexibility. , Thus, finding a proper separator material for ZM DIBs requires advanced troubleshooting and surpassing standard schemes.…”

Zn/alkali metal dual-ion batteries (ZM DIBs) with highly concentrated water-in-salt (WiS) electrolytes are promising next-generation energy storage systems. This enhanced design of Zn-ion rechargeable batteries offers intrinsic safety, high operating voltage, satisfactory capacity, and outstanding cyclic stability. Herein, taking the concept of highly concentrated electrolytes one step further, we introduce water-in-salt gel biopolymer electrolytes (WiS-GBEs) by encapsulating Zn/Li or Zn/Na bisalt compositions in a cellulose membrane. WiS-GBEs inherit the electrochemical merits of highly concentrated electrolytes (i.e., wide voltage window, high ionic conductivity, etc.) and excellent durability of gel biopolymer structures. Both types of WiS-GBEs apply to coinand pouch-cell compartments of ZM DIBs, offering a high plateau voltage (>1.8 V vs. Zn 2+ /Zn), good and reversible capacity (118 and 57 mAh g −1 for Zn/Li and Zn/Na cells, respectively), and outstanding cycling stability (more than 90% after 1,000 cycles). Essentially, the pouch cells with WiS-GBEs present superior durability, flexibility, and capacity endurance under various bending stress conditions (90% capacity retention under 0−180°b ending modes), indicating their potential capability to power wearable electronics. The practical powering ability of Li-and Nabased pouch systems is demonstrated by the example of a wearable digital timer.
