Recipe for safer batteries - Just add diamonds
Philadelphia PA (SPX) Aug 28, 2017
While lithium-ion batteries, widely used in mobile devices from cell phones to laptops, have one of the longest lifespans of commercial batteries today, they also have been behind a number of recent meltdowns and fires due to short-circuiting in mobile devices. In hopes of preventing more of these hazardous malfunctions researchers at Drexel University have developed a recipe that can turn electrolyte solution - a key component of most batteries - into a safeguard against the chemical process that leads ... read more
