Thermoresponsive Gel Polymer Electrolytes Enabled by Retained Double Bonds for Thermal Shutdown in Lithium‐Ion Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A smart gel electrolyte with thermal shutdown capability has been proposed enabled by a two‐step cross‐linking strategy, which preserves a high density of unreacted double bonds at room temperature. This strategy brings negligible degradation to room temperature electrochemical performance, while under thermal abuse conditions above 115 °C, the gel ...

A convenient preparation of vic-iodo-isocyanates

open access: yes, 1983
vic-Iodo-isocyanates are conveniently prepared by treatment of alkenes with iodine/thallium(1) cyanate or with iodine(I) chloride/thallium(I) cyanate. Treatment of the phenylurea (5) with silver perchlorate or m-chloroperbenzoic acid gives the oxazoline (
