All‐Solid‐State Batteries: High Active Material Loading in All‐Solid‐State Battery Electrode via Particle Size Optimization (Adv. Energy Mater. 1/2020)

In article number 1902881, Gerbrand Ceder and co-workers demonstrate that the active material loading in all-solid-state batteries is largely controlled by the active material and solid electrolyte particle size ratio. A generalized guideline is provided for increasing active material loading via particle size optimization, and a composite cathode with >50 vol% active material loading is experimentally demonstrated.
