Ionic liquids are used electrochemically, for example, as electrolytes of rechargeable batteries.1,2) Watanabe and co-workers have developed a novel solid electrolyte in which an ionic liquid is confined in a network polymer called "ion gel".3) This ion gel is expected to contribute to solidification of various electrochemical systems and safety improvement as it exhibits exceedingly high ion-conductivity compared with conventional solid polymer electrolytes.
