Dyson charges up US battery technology firm with $15m investment

3 Mins

It marks Dyson’s first investment outside of the business, which has generated revenue in the billions from its development of vacuum cleaners and hand dryers – now, Satki3 is expected to support further business growth by providing the firm’s gadgets with more power and efficiency.

Using what’s called “solid-state battery technology”, Satki3 replaces the standard liquid electrolyte and electrodes found in batteries with solids to double the amount of energy storage, thus producing more powerful results. Although still in development, the latest round brings the company’s total investment to $50m.

The team itself is led by co-founder and CEO Ann Marie Sastry, who trained the core team personally. Prior to launching Satki3, she had secured more than 25 years of leadership and technical knowledge, and has worked as the professor of engineering at the University of Michigan, which resulted in the company being spun out of the educational establishment.

James Dyson, founder and chief engineer at Dyson, said: “Sakti3 has achieved leaps in performance which current battery technology simply can’t. It’s these fundamental technologies – batteries, motors – that allow machines to work properly.

“The Sakti3 team has amazing ambitions, and their platform offers the potential for exponential performance gains that will supercharge the Dyson machines we know today.”

In Satki3’s own pitch, it claims to be “developing energy storage technology to improve peoples’ lives – in consumer electronics, grids, and vehicles.” In the case of General Motors, the vehicle maker’s interest lies in the opportunity to have solid-state batteries powering its electric range of cars with a view to outstrip the competition.

Additionally it boasts its “data-driven environment offers you [the employee] the opportunity to contribute whether you’re a chemist, materials scientist, business development, or manufacturing specialist.”

Speaking of Dyson’s involvement, Sastry said: “It was an honour to be approached by Dyson because it wanted what we did – much, much better batteries. There is a great deal of knowledge and passion on both sides, and Dyson’s engineering team has the capability and the track record to scale up new ideas and make them a commercial reality.”
