Thickness-Gated Water and Electron Transport in Near-Critical Ultrathin Polyethylene Membrane Electrodes.

Electrochemical systems are constrained by a materials paradox: chemically robust porous separators are typically hydrophobic and electronically insulating, forcing bulky, carbon-rich interfaces to couple mass transport and electrical contact. Here we show that pushing freestanding porous polyethylene into a near-criti...
