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 .
