Swapping electrolytes could prevent big battery fires

Fires allegedly caused by the lithium-ion batteries in Boeing 787 Dreamliners and Tesla Model S vehicles have sparked concern about the future of these technologies. Researchers now say they have designed a new model of nonflammable lithium-ion battery that is as effective as what is already in use.

Current lithium-ion batteries use a polymer-based electrolyte made of an alkyl carbonate. Tests of a different electrolyte called a perfluoropolyether (PFPE), which is similar in structure to the a...
