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

Adv Mater. 2017 Jan;29(2). doi: 10.1002/adma.201603755. Epub 2016 Oct 26.

Abstract

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 .

Keywords: Li-metal; anodes; batteries; poly(dimethylsiloxane) film.
