$15 million investment by Dyson could lead to longer smartphone battery life
No one is happy with the battery life on their smartphone. Even those with cells that keep their phone humming for more than a day without needing a recharge would love to have longer battery life. So that is why there is some good news on that front today as home appliance manufacturer Dyson has invested $15 million into a promising technology that could double the life of the battery in your handset.

The money was given to a University of Michigan spinoff called Sakti3. The new technology developed by the company uses solid lithium electrodes instead of a mix of chemical liquids to help its batteries store more than 1,000 watt hours per liter, double what the top lithium batteries can store today. That leads to an energy density of up to 620 watts per hour per liter, allowing mobile electronics to run longer between charges.

Even better, the batteries are cheaper to produce, better for the environment, and run longer before needing a replacement when compared to today's lithium-ion cells. And the best part is that since they would no longer contain a volatile cocktail of chemicals, these batteries would be less likely to explode in your pocket.

Dyson has signed a joint development agreement with Sakti3, promising to help commercialize the solid state batteries. If they do everything that is said about them, this could be quite an easy task for the company, well known for its line of vacuum cleaners.

finally some new battery tech cant wait to see these types of batteries in phones (every electronic device) in the near future.

More importantly, how good are the yields when mass producing them. I'd imagine with more pure materials you'd run in to a lot of waste.

Only 15 million? If R&D was that cheap on something as crucial as battery longevity, we would have seen a bigger boon by now.

" batteries are cheaper to produce [...] and run longer before needing a replacement", and that's why we'll never see them on the market.

"No one is happy with the battery life" No one? lol? I'm very satisfied with my Sony Z3

So, this will mean smartphone battery prices will jump 600%?

I hope it works and that those batteries soon come to the market.Battery lasting at least 3 days is the glory!

When will come a uranium battery?

What'll happen since they double the capacity of current batteries, OEMs will continue to make thinner phones since these new batteries will allow them to put a smaller battery that have the same capacity of today's batteries. So while this may be good in terms of battery tech, it won't be good for consumers as they'll just go with smaller batteries in the name of thinner and lighter!

We need these kinds of battery tech advancements! Hope to see this soon.

This will not lead to longer smartphone battery life. Smartphone battery life will remain the same. Instead, smartphones will be thinner. Apparently the quest to be able to slice vegetables with your smartphone is taking precidence over battery life.

I've lost count of how many universities, small companies and groups that have discovered new ways of improving the density of battery components and/or increasing storage capacity to allow longer usage between charges. If this happens, batteries last longer and sales decrease. 15 million is a lot of cash. But, the red tape hurdles to beat the battery manufacturers such as Panasonic, Rayovac, Duracell, Eveready etc, will be a tough road. The best we can hope for currently, is for software developers and processor engineers to make these things more efficient to run on present battery technology. John B.
