Dyson’s latest venture could double your smartphone’s battery life


iPhone battery warning

Dyson has agreed to invest $15 million in a new battery technology that could double the battery life of future smartphones.

It’s financing a University of Michigan spin-off called Sakti3, whose ‘next generation’ battery technology can reportedly hold twice the energy of existing rechargeable batteries, as reported by The Guardian.

This means we could see electric cars manage a range of up to 600 miles per charge, although anything with rechargeable batteries could benefit, including smartphones, tablets, and laptops.

Sakti3 has achieved the impressive feat by switching out the liquid innards of current batteries.

Instead of using a liquid mix of reactive compounds, Sakti3 uses solid lithium electrodes that can manage significantly higher energy storage.

James Dyson, the company’s founder, said: “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.”

According to Sakti3, the solid-state batteries can store upwards of 1,000 watt hours per litre.

As well as improving the battery life of gadgets, that increased energy density could also see portable technology become significantly thinner and lighter because batteries won’t take up so much physical space.

Ann Marie Sastry, Sakti3’s founder and chief executive, said that Dyson’s investment will help speed up the process of bringing its battery technology to consumers.

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,” she said.

When we will actually see the technology is harder to say; Dyson’s agreement does say that the batteries will appear in its own products first, however.

Great news we definetely need to improve the battery life on all our tech gadgets. This area seems to have been neglected too often considering all the other hardware advancements.

Agree, though often battery life seems to be sacrificed in the pursuit of thinness - Apple seem to be the worst offenders in this regard. I'd take slightly thicker smartphones, tablets and laptops if it meant I got better battery life.

Sorry guys, did you not read this bit "..

see portable technology become significantly thinner and lighter because batteries won’t take up so much physical space". As usual the focus is not battery life.

Thats the point though if they can make them smaller and thinner then they can still fit a larger capacity if you know what I mean.

Agreed I think most of us would be wiilling to have slightly thicker devices if it mean an improvement in battery life. Besides how thin and light do they want these devices to get without becoming fragile. Remember the whole Iphone 6 plus bending fiasco.

Thanks Pg - must have skimmed over that. I hope manufacturers use this technology to keep phones, tablets & devices at existing sizes but with double the battery life, instead of going after ever more thin devices (or only to do so where it's needed).

I've been reading stories like this over a decade and somehow they never make it to market. The technology can work, but you have to make it work and be economical on an industrial scale.

And often the technology doesn't work in some key aspect. It might store more charge but degrade quicker through recharging, or take too long to charge ("solid electrodes" make this seem plausible), or be too unstable for consumer use (the things can already catch fire or explode).

So good luck to it and the dozens of other revolutionary approaches to improving battery life; hopefully one of them will make it.

Still awaiting fuel cells...

Did someone mention Dyson? More likely to double the cost.

Apple phone with a Dyson battery.

My eyes are starting to water....still who needs a pension pot.
