摘要

The image representing article number 2000467 by Martin Kaltenbrunner and co-workers shows the mixing of the two phases that form a polyHIPE, a process in which UV-curable monomers and an electrolyte solution are brought together, to form a highly porous, ion conductive structure. The use of such polyHIPEs as high-performance separators in stretchable batteries pushes the limits of soft energy sources for autonomous wearables and soft robots.
