Dyson has invested $15m in Michigan-based solid-state battery maker and developer Sakti3, in a bid to radically improve current mobile devices' battery lives.
The investment will see Dyson integrate Sakti3's next-generation battery technologies into its technology portfolio over the next four years.
Dyson said it invested in Sakti3 in a bid to overcome challenges resulting from fundamental flaws in Lithium ion (Li-ion) battery technology, which it claims discharge too quickly and are too bulky.
Satki3 aims to fix this by replacing the reactive liquid compounds used in competing batteries with solid lithium electrodes.
Satki3 said the change means its products can store 1,000 watt hours per cubic litre, a marked improvement on the average 620 per cubic litre stored by other lithium-ion batteries.
Sakti3 claims the technology is also easier, cheaper and safer to mass produce.
Dyson founder and chief engineer James Dyson announced plans to use the technology to "double the life" of most smartphones, and explore its application in other projects.
"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," he said.
"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."
Sakti3 founder and chief executive officer Ann Marie Sastry said she expects the investment to help the firm further improve its batteries' performance in the near future.
"It was quite an honour for us to be approached by Dyson, precisely because they wanted what we did - much, much better batteries," she said.
"The truth is, 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. Together we will enable some very transformative products."
Traditionally smartphone makers, such as Samsung with its Galaxy S6, have worked to improve battery performance by increasing their capacity, adding quick charge or wireless charging technology, or using more efficient internal components.
