Perpendicularly Aligned Superionic Pathways Enable Pressure-Less Solid-State Lithium Batteries

Abstract

A fundamental trade-off between ionic conductivity and mechanical compliance has long constrained the development of composite solid electrolytes. Cheng et al. address this challenge through a biomimetic electrolyte architecture featuring continuously aligned superionic pathways that decouple ion transport from mechanical flexibility. This architectural design establishes a new paradigm for composite electrolyte engineering and provides a promising route toward practical pressure-less solid-state batteries.
