Unlocking Sustainable-by-Design Li-Metal Batteries by Recycled PVB in Blend Polymer Electrolytes.

ABSTRACT: In today's sustainability-driven society, the circular economy has emerged as a guiding principle for responsible resource use, aiming to transform production by prioritizing reuse, repair, and recycling, thus extending product lifecycles and reducing waste. Herein, the impact of the circular economy on upcycling, focusing on poly(vinyl butyral) (PVB), widely used as an interlayer in laminated glass, recovered from automotive waste via a patented mechanochemical process, is investigated. For the first time, this process is applied in an innovative closed-loop design for solid polymer electrolytes (SPEs) in Li-metal batteries (LMBs). A green, solvent-free method produces polymer blends of PVB, ensuring outstanding mechanical properties, and poly(ethylene oxide) (PEO) as the ion-conductive m
