ASSLMBs, which use lithium metal as the anode, are considered promising next-generation energy storage devices. This study aims to overcome these issues by developing a high-performance composite electrolyte (CPE) through the combination of a 3D interconnected porous LAGP ceramic framework and an elastomer electrolyte. The CPE effectively suppresses the growth of lithium dendrites through the robust physical barrier provided by the LAGP ceramic framework, while the elastomer electrolyte contributes additional flexibility and excellent resilience, mitigating volumetric changes that may occur during battery operation. The 150 µm thick CPE developed in this study achieved a high ionic conductivity of 2.11 x 10-4 S/cm and a low ASR value of 72 ohm cm2, recording an excellent capacity of 147 mAh/g at 0.1 C. This represents a significant advancement in the development of all-solid-state lithium-metal batteries, demonstrating the potential for high-performance, safe energy storage solutions.
