"High Areal Capacity and Long Cycle Life Flexible Mild Quaolid-State Ag" by Yanzhe Zhu, Renbo Zhu et al.
Silver-zinc (Ag-Zn) batteries are a promising battery system for flexible electronics owing to their high safety, high energy density and stable output voltage. However, poor cycling performance, low areal capacity, and inferior flexibility limit the practical application of Ag-Zn batteries. Herein, we develop a flexible quasi-solid-state Ag-Zn battery system with superior performance by using mild electrolyte and binder-free electrodes. Copper foam current collector is introduced to impede the growth of Zn dendrite, and the structure of Ag cathode is engineered by electrodeposition and chlori...
