A new EV battery shows big promise

For decades, battery researchers have toiled away trying to crack the code for a new battery that could trump lithium-ion batteries — the technology that brought the electric vehicle industry to where it is today.

Now a decade-old startup backed by members of the tech investing elite and global auto giants says it has created working batteries that could lead to electric vehicles with significantly longer ranges, that can be produced at a lower cost, are safer to operate, boast longer lifespans and support faster charging.

Meet QuantumScape, a battery company that’s been in stealth for a decade while its team has worked on developing what the industry calls a solid-state, lithium-metal battery. The solid-state moniker refers to the elimination of the liquid electrolyte, which in traditional batteries fills the cell and is used for charging and discharging.
