Student Invents Phone Batteries That Last for 400 Years

Remember how mobile phones in the 90s used to last around week or more without needing a single charge? Those were the good old days. Now, we’re lucky if our battery life lasts the day.

Things could be about to change, as a student seems to have invented a phone battery that can last for weeks, months, and even years… in fact, it can last for up to FOUR. HUNDRED. YEARS.

Mya Le Thai, who is currently studying for her PhD at the University of California, stumbled upon the discovery pretty much by accident. The team she was working with were just looking into how to improve nanowires for standard rechargeable batteries, but this led onto the much more impressive discovery.

Chair of UCI’s chemistry department, Reginald Penner, commented on what Mya found:

“Mya was playing around, and she coated this whole thing with a very thin gel layer and started to cycle it. She discovered that just by using this gel, she could cycle it hundreds of thousands of times without losing any capacity. That was crazy, because these things typically die in dramatic fashion after 5,000 or 6,000 or 7,000 cycles at most.“

Nanowires make great electricity conductors, but are incredibly fragile and break after a few thousand uses. Incredibly, Mya managed to counteract that.

OK, so the battery is resistant to a lot of use, but it’s not like you could simply charge your phone once and it would last a lifetime. Still, it would save you money on having to buy a new phone when the battery begins to burn out.

We could definitely do with this. Fingers crossed Amazon gets some in stock ASAP.
