Toward Higher Energy Density All‐Solid‐State Batteries by Production of Freestanding Thin Solid Sulfidic Electrolyte Membranes in a Roll‐to‐Roll Process

Advanced Energy Materials, EarlyView.
The scalable production of a thin, but mechanically stable, and still flexible argyrodite solid electrolyte membrane is presented. It is fabricated and laminated onto a supporting non‐woven fabric in a concerted step using a continuous, industrially relevant, solvent‐free, roll‐to‐roll process. With this approach, a promising energy density of 670 Wh L−

A “Cool” Route to Battery Electrode Material Recovery

Advanced Energy Materials, EarlyView.
Ice‐stripping, a novel sub‐zero electrode delamination technique, enables >90% recovery of the electrode materials from manufacturing scrap and end‐of‐life batteries. Water is sprayed upon a porous electrode and quickly freezes when placed on a cold surface. The foil is peeled away, leaving behind the black mass with the morphology retained.
