The home appliance manufacturer recently invested $15 million into your cell phone’s power source.

At the moment, one of the most important purchases that you can make is the best portable charger that you can find, because the current smartphone battery life typically does not keep up with what we need every day.

Even the top of the line mobile devices with long lasting batteries could still stand for a longer life.

Dyson has been watching this smartphone battery life trend and has decided to step beyond home appliances (such as their famous and much beloved vacuums), and into the world of rechargeable power with an investment of $15 million into a promising new tech that could double the current length of time that you’ll be able to get from a single charge in your handset. While this certainly won’t eliminate the need for a backup battery pack, it will at least reduce the number of times that you will need to use one in a given week…one day.

If this technology works out, it could mean that smartphone battery life may one day actually fit realistic device use.

The investment was made into Sakti3, which is a spinoff of the University of Michigan. The new rechargeable smartphone battery technology was developed by that company through the use of solid lithium electrodes, as opposed to the current mixture of liquid chemicals. This would make it possible for batteries to achieve storage levels greater than 1,000 watt hours per liter. That represents double the levels of the best lithium batteries that you’ll find, today.

This also leads to up to 620 watts per hour per liter in energy density. What that means is that mobile devices will be able to keep running for much longer between their different charges. The founder of Dyson, James Dyson, explained his support for the technology that Sakti3 has been developing. He explained that it “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.”

What’s more – and possibly the best news for those of us who will be purchasing these devices with better smartphone battery life in the future – is that these rechargeable power sources are even cheaper to produce than the current tech. They are also greener, having less negative impact on the environment, and they will continue to run for much longer before they need to be replaced, when compared to the lithium-ion cells of today.
