| Summary: | Solid-state batteries (SSBs) with projected high safety and high-energy density have been heavily pursued as the next generation of electrochemical storage devices, while their realization still faces challenges, including scalable fabrication process, high-loading electrode, and robust thin solid electrolyte. Dry electrode technology (DET) is an emerging battery preparation method that embodies with numerous advantages, including simplified production procedures, loading-enhanced electrode, as well as elimination of solvent sensitivity. Currently, the DET is of great interest for its potential capability in upgrading the slurry-based SSB system that we are experiencing. Herein, the issues encountered in the wet process and the corresponding remedies by DET are introduced, followed by a summarization of multiple DET methodologies. The latest developments of DET are analyzed separately in terms of its application in cathode, anode, and solid electrolytes with emphasis on manufacturing method and material science. Binder selection, which has a growing influence on the quality of the dry film, is discussed as well. Based on the insights acquired, future potential attempts at DET are proposed to meet the goal of SSB commercialization. |
