Engineers report progress toward lithium-metal batteries that charge fast -- as fast as an hour. This fast charging is thanks to lithium metal crystals that can be seeded and grown -- quickly and ...

Liquid electrolytes enable fast ion transport but can raise safety concerns, and lithium metal anodes—despite their high capacity—can grow dendrites that trigger short circuits and rapid failure.

Lithium was supposed to be soft. The metal bends easily in bulk form, stretches before it breaks, and deforms the way you might expect a pliable material to behave. Scientists who studied the tiny ...
