Dyson invests $15m in technology that may double smartphone battery life.

Dyson is investing $15m in a new type of battery that promises to double smartphone battery life and allow electric cars to drive over 600 miles per charge.

The British vacuum company was alerted to the University of Michigan spin-off called Sakti3, which has developed next generation solid-state technology that can store twice as much energy as traditional rechargeable batteries.

Solid state batteries could be made thinner, lighter and safer, while storing twice as much energy effectively and doubling smartphone battery life.
