High-Loading Dry-Electrode for all Solid-State Batteries: Nanoarchitectonic Strategies and Emerging Applications

Abstract

Abstract 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.
