Batteries without the fire hazard … and a longer life. Things are getting better.
Researchers have developed a new material for a basic battery component that they say will enable almost indefinite power storage. The new material — a solid electrolyte — could not only increase battery life, but also storage capacity and safety, as liquid electrolytes are the leading cause of battery fires. . . . Another advantage of a solid-state lithium-ion battery is that it can perform under frigid temperatures.
