Aluminum Sulfur—Is This How the Future Spells Lithium Ion?
"The nascent battery already has an energy density comparable to that of today’s lithium-ion batteries at cell level, and should come in at less than a sixth of the cost, the team reported in Natureon 24 August. The battery also charges in minutes and is nonflammable thanks to its molten salt electrolyte that does not burn. “You can put a blowtorch to this thing and it won’t catch fire,” says Sadoway."
