Poly(dimethylsiloxane) Thin Film as a Stable Interfacial Layer for High‐Performance Lithium‐Metal Battery Anodes

A modified poly(dimethylsiloxane) film with nanopores, fabricated through a scalable and low-cost process, can serve as a protective layer for improving lithium-metal anodes. This film can suppress Li-dendrite formation because of its chemical inertness and mechanical properties. Stable cycling over 200 cycles with an averaged CE of 94.5% is demonstrated at 0.5 mA cm−2.
