Dyson joins General Motors and Khosla Ventures as an investor in Sakti3's solid-state battery technology.

Dyson is best known for its snazzy vacuums that look a bit like Transformers Autobots, but the U.K. company also has its sights set on developing battery technology to increase cellphone life, power electric vehicles and complement home-based renewable energy systems.

The company announced Monday, March 16, that it will invest $15 million in battery company Sakti3, an offshoot of the University of Michigan. 

Sakti3 is engineering solid-state batteries that use lithium electrodes instead of chemical liquids, a promising approach that could eventually replace lithium-ion batteries in use today. The company claims that its batteries can store more than 1,000 watt hours per liter, with an energy density of 620 watts per hour per liter, which would double the storage found in current batteries.

Additionally, Sakti3's solid-state batteries are cheaper to produce and less detrimental to the environment. Though their introduction will likely be several years down the road, Dyson's support in the form of a joint development agreement will help commercialize the technology for a variety of uses.
