and excellent mechanical strength characterize the solid hybrid polymer (SHyP) network presented here. The material allows block copolymer processing into nanometer-scale plates and rods, paving the way to the fabrication of lithium-conducting cables and eventually solid-state electrochemical devices of sizes down to 10 nm.
