Quasi Solid State News Today

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 ...

In-situ self-transformation is proved to be an effective strategy to design high-performance cathodes for aqueous zinc-ion batteries (ZIBs). However, the inferior transformation efficiencies during phase transition limit its further application. Herein, a 3D spongy VO -graphene (VO -rG) precursor has been designed for achieving the ultra-efficient in-situ self-transformation process from VO -rG into multifaceted V O ·nH O-graphene composite (VOH-rG). Benefiting from the highly conductive hetero...
