The Flexible and Stable 3D Zn Electrode for High-Power Density Zn Metal Batteries

A flexible Zn film electrode with ionic and electronic networks 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 Zn 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.
