A Review on the Fabrication and Manufacturing Processes of All-Solid-State Batteries From Laboratory Research to Industrial Scale-Up

With the advancement of electric vehicle (EV) battery technologies, conventional lithium-ion batteries are approaching their theoretical energy density limits while facing persistent safety concerns. All-solid-state batteries (ASSBs) offer a pathway toward higher energy density and enhanced safety. This review focuses on the fabrication and manufacturing processes of ASSBs, explicitly bridging laboratory-scale research methods with emerging industrial-scale production routes. Emphasis is placed on material systems, scalable processing strategies, manufacturing bottlenecks, and industrial roadmaps.
