A Janus-type quasi-solid-state electrolyte enabling dual-ion relay for long lifespan of nonaqueous zinc batteries

Abstract

An anhydrous Janus electrolyte with a spontaneously formed ionic double layer enables efficient dual-ion relay conduction, overcoming inherent kinetic barriers in low-salt-concentration solid systems, and delivers unmatched Zn anode stability and full cell durability across a wide temperature range.
