Constructing Electronic and Spatial Barriers: A Practical Strategy for High-Performance All-Solid-State Lithium Metal Batteries

at 0.1 C, high-rate performance at 3 C, and excellent cycling performance of 80.69% capacity retention ratio after 900 cycles. This work delineates a versatile design paradigm for developing dense, electronically insulating composite electrolytes, paving the way for dendrite-free and highly stable ASSLMBs.
