A Breakthrough Battery Gets a Big Backer

A startup with radical new battery technology gets a vote of confidence from an appliance maker.

Battery life constrains the appeal of consumer electronics and electric vehicles.

A lithium-ion battery that stores twice as much energy is a step closer to commercialization thanks to a deal with the U.K. home appliance company Dyson.

Ultrathin battery prototypes undergo testing at the labs of startup Sakti3.

The startup Sakti3 announced today that it has signed a joint development agreement with Dyson, which makes vacuum cleaners and other appliances, to incorporate its batteries into new products. The companies didn’t say when those products will be available, but one could be a cordless vacuum cleaner. Dyson also announced a $15 million investment in the startup.

Sakti3 uses new materials and manufacturing techniques to achieve higher energy density. The company’s battery does away with the flammable liquid electrolyte used in conventional lithium-ion batteries, which makes it feasible to use a different set of high-energy storage materials (see “Solid-State Batteries” and “A Battery for Electronics That Lasts Twice as Long”).

The technology could have many applications, including electric vehicles, the range of which is limited by the size and cost of conventional batteries.

In a statement, Dyson founder and chief engineer James Dyson said, “Sakti3 has achieved leaps in performance which current battery technology simply can’t.”

Many battery startups have struggled to translate impressive lab results into products (see “Why We Don’t Have Battery Breakthroughs”), in part because their prototypes are custom-made, often using expensive manufacturing techniques that can’t easily be scaled up. Sakti3 makes its prototypes on standard manufacturing equipment, and this could help ensure that the technology, once perfected, can be commercialized.

Success isn’t a sure thing. Making a few prototypes might not translate to high yields in a factory, where conditions and raw materials can vary. But the partnership with Dyson, which has manufacturing experience and relatively deep pockets, could make the transition easier for Sakti3.
