Composite polymer electrolytes (CPEs) are attractive materials for solid-state lithium metal batteries, owing to their high ionic conductivity from ceramic conductors and flexibility components. As with all however, CPEs face the challenge of dendrite formation propagation. Not only does this lower critical current density (CCD) before cell shorting, but uncontrolled growth deposits may limit Coulombic efficiency (CE) by creating dead lithium. Here, we present a fundamental study on how...
