$15 million investment by Dyson could lead to longer smartphone battery life

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.

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!

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.
