▎ 摘  要

NOVELTY - Zinc film electrode comprises an ionic liquid based gel polymer as a binder. USE - Zinc film electrode for a rechargeable zinc metal battery. ADVANTAGE - The zinc electrode has been designed by utilizing ionic liquid based gel polymer as the binder, which can minimize the interface resistance between electrode and electrolytes. Ionic liquid electrolytes are good candidates for high surface area zinc anode due to their good electro(chemical) stability. Ionic liquid-based gel polymer electrolytes (GPEs) are good candidates to replace liquid electrolytes or separators in some special applications, like surface coating structure batteries. The zinc electrode can facilitate the development of rechargeable zinc metal batteries (RZMBs) which have the high theoretical capacity (820 mAh/g), low redox potential, and intrinsic safety. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: 1. a rechargeable zinc metal battery, which comprises zinc film electrode comprising an ionic liquid based gel polymer as a binder; and an electrolyte; 2. a membrane, which comprises a gel polymer including a fluorinated polyolefin; 3. a electrode, which comprises membrane; 4. a battery, which comprises electrode and an electrolyte; and 5. a method for manufacturing an electrode, which involves casting a mixture of a gel polymer including a fluorinated polyolefin, an electrically conductive material, and a multiple of metal particles to form a wet film; and drying the wet film.
