Samsung Develops 900Wh Solid-State Battery Prototype

The dominance of lithium-ion batteries may be coming to an end, if Samsung’s latest solid-state battery prototype makes it to market.

Solid-state batteries are highly desirable, but someone needs to perfect their design and manufacture. They use a solid electrolyte, making them non-flammable; avoid using a number of toxic materials; and hold the promise of energy densities up to 2.5 times that of lithium-based batteries. But one challenge engineers need to overcome is dendrites, which are crystals that form on the anode and greatly shorten the life and impact the safety of the battery.
