Solid state batteries, with their high energy density and superior safety, could be a game-changer for the electric car industry, for electronics, and for grid storage. But successful fabrication of All-Solid-State Batteries (ASSBs) with ceramic electrolytes is limited by processing difficulties and interfacial challenges. Berkeley Lab researchers have developed a suite of low-cost approaches that could enable the large scale fabrication of thick electrodes for ASSBs and the utilization of sustainable materials.
Learn about the latest in solid state battery technologies including: Structurally resilient ASSBs using rigid and soft solid electrolytes with successful cycling against lithium metal anodes (winner of an R&D 100 Award in 2020); Scalable fabrication of porous ceramic (LLZO) electrodes for solid state batteries; Thin solid state electrolytes with enhanced critical current density and stable cycling; and Battery cells with organic cathodes and solid electrolytes, with a theoretical specific capacity 50% higher than that of nickel manganese cobalt (NMC) cathodes.
