Jelly Batteries – A Better Solution

In a jelly battery the jelly would replace the liquid electrolytes currently used in most lithium batteries.  University of Leeds dreamed up a very unique solution to our never-ending-quest for more battery power.

A new prototype of battery, the jelly battery, avoids what the pros call “thermal runaway.”  The thermal runaway is what causes batteries to over heat and [sometimes] catch on fire.

The Leeds research team says their secret to success lies in the blending of a rubber like polymer with a conductive, liquid electrolyte into a thin, flexible file of gel.  That film sits between the battery electrodes.

“Safety is of paramount importance in lithium batteries. Conventional lithium batteries use electrolytes based on organic liquids; this is what you see burning in pictures of lithium batteries that catch fire. Replacing liquid electrolytes by a polymer or gel electrolyte should improve safety and lead to an all-solid-state cell,”

said Professor Peter Bruce from the University of St Andrews, who was not involved in the study.
