Current battery research is primarily directed towards enhancing productivity optimization, reducing energy consumption, and improving battery performance, especially in addressing the hurdles of state-of-the-art battery production. The achievement of batteries with simultaneous high safety and energy density relies on the advancement of all-solid-state batteries utilizing robust solid electrodes and thin solid electrolytes. To achieve this, different electrode manufacturing processes from conventional techniques are required. Dry-electrode technology is an innovative concept and technique that enables the manufacture of electrodes through a "powder-film" route without the use of solvents. Dry-electrode technology can simplify manufacturing processes, restructure electrode microstructures, and enhance material compatibility. This review summarizes the concept and advantages of dry-electrode technology and discusses various efforts towards performance and efficiency enhancement. Dry-electrode technology is expected to contribute to the production capability of the next-generation battery industry with improved stability and energy density, promising a sustainable future.
