Now, they have made the nonflammable prototype even better, replacing the liquid electrolyte with a liquid-solid hybrid that makes the battery more conductive and more resistant to damage.<\/p>\n<p>\u201cA non-liquid electrolyte is better because the battery can\u2019t leak, which makes it safer,\u201d said Dominica Wong, who led last year\u2019s findings at UNC-Chapel Hill and who is co-author of this year\u2019s work, which appears in the <em>Proceedings of the National Academy of Sciences<\/em>. \u201cFor traditional liquid batteries, casing design around the battery pack is extremely important to prevent battery failure. With solid electrolytes, batteries can be made more flexible and robust against compression, which is important for several applications.\u201d<\/p>\n<p>The new work builds on the nonflammable material that DeSimone, Wong and their colleagues developed last year. In the new study, that same material \u2013 called perfluoropolyether \u2013 was attached to particles of glass to create a nonflammable film with high conductivity at room temperature.<\/p>\n<p>Read
