Preparation of Next-Generation Rechargeable Battery Anodes Using Aerosol Process and Evaluation of Their Charge–Discharge Performances

Abstract

When an aerosol, comprised of a carrier gas and powder particles of metal, alloy, or oxide, is sprayed at a high speed onto a substrate, a compacted powder is deposited to form a thick film on the substrate. The authors have applied for the first time this aerosol process to the preparation of rechargeable battery electrodes, and have revealed that the process has unique advantages as anode materials with high capacities. In this review, we introduce highlights of our successful results obtained by the material development of Li-ion battery anodes, and mention a future outlook for the development of the next-generation battery from the viewpoint of the potential of the aerosol process.
