“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.
