Our smartphones and wireless gadgets are our lifelines but we aren’t completely free to move about, we still need a power source. Batteries don’t last forever and some days, it seems like they don’t last long enough at all. Science may have an answer to give us more juice for our devices soon though. They’ve stumbled across a way to increase battery life up to 400 times what it is now.

The batteries in most of our devices are lithium which makes them rechargeable but the more we charge them, the more they corrode until they can’t be charged at all. In trying to figure out a way to combat this problem, researchers at UC Irvine accidently figured out how to make your battery live forever (ish). Using gold nanowires in place of the common lithium allowed them to recharge their battery without decline.

Now this technology is in the very early stages and it may be some time before we see it on the market. Plus, even though it’s using only a tiny bit of gold, the materials make it more expensive. Of course, I don’t know anyone who wouldn’t pay to make sure their phone battery doesn’t ever need to be replaced.
