Dyson may be more famous for vacuum cleaners, hand dryers, and bladeless fans, but the British electronics giant is spreading its wings with the news that it’s investing $15 million in Michigan-based solid-state battery company Satki3.


The money is part of a larger $20m investment round in Sakti3 that includes a deal to commercialise the company’s research and incorporate it into Dyson products.

“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.”

Most batteries in commercial use today rely on lithium-ion technology which contains a pressurised flammable electrolyte, which is vulnerable to damage, and also means they are heavy and limits their ability to store power.

Solid-state battery advantages

Solid-state batteries do away with the liquid electrolyte, and instead replace it with a metal one which coats the battery’s electrodes. As well as being safer and able to withstand higher temperatures, using a metal electrolyte means more exotic materials can be used which store more energy, making the solid-state batteries more powerful, smaller and lighter.

Satki3 achievements

Sakti3 has been investigating how to improve batteries for almost a decade, since the company was spun out of the University of Michigan. Along the way it attracted $50m in equity investments, including from Khosla Ventures, Beringea, Itochu and General Motors.

Sakti3 named as one of MIT’s most innovative companies began by computer modelling the technology and is now scaling up prototype batteries into production.

“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.”

Well, let's wish them good luck and wait for the solid-state batteries available to buy in the nearest future.

    Dyson Ltd is doing a fantastic job with their investments currently, and I want to read the new ceo reviews to learn more about their investment techniques. That would be fantastic, to be honest.
