Sakti3, an offshoot of the University of Michigan's engineering department, develops solid-state battery cell prototypes. The team claims to have achieved an energy density exceeding 1,100 Wh/l, which it says is double that of commercially available lithium-ions. That explains why Dyson has invested $15 million in Sakti3-related research and development, and promises to be the first to bring this battery tech to market.
In short, if you have two identically-sized batteries -- but one has a higher energy density -- the one with a higher energy density will last longer. Theoretically, this also means that you could reduce the size of a battery without sacrificing its longevity.
There are a ton of applications for this type of technology, ranging from electric vehicles to smaller home appliances and Dyson, along with General Motors and a handful of other companies, are staking millions on Sakti3's energy density claims.
Last year, Dyson invested, announced plans for a and set aside , including a vague roadmap about introducing 100 new products in four new categories over the next four years.
While we still don't know many of the details surrounding these recent investments, it certainly seems plausible that Sakti3 will play a major role -- as long as its tech holds up, that is.
