Sulfonated‐ TiO 2 Nanorod–Reinforced PEO Composite Solid Electrolytes for High‐Voltage Solid‐State Lithium Metal Batteries
Solid‐state lithium batteries (SSBs) represent a promising next‐generation energy storage technology, yet the practical application of poly(ethylene oxide) (PEO)‐based solid polymer electrolytes (SPEs) is hindered by limited ionic conductivity and poor oxidative stability at high voltages. In this work, we present a...
