Instead of lithium, researchers at UC Irvine have used gold nanowires to store electricity, and have found that their system is able to far outlast traditional lithium battery construction. The Irvine team's system cycled through 200,000 recharges without significant corrosion or decline.
The Irvine battery technology uses a gold nanowire, no thicker than a bacterium, coated in manganese oxide and then protected by a layer of electrolyte gel. The gel interacts with the metal oxide coating to prevent corrosion. The longer the wire, the more surface area, and the more charge it can hold. Other researchers have been experimenting with nanowires for years, but the introduction of the protective gel separates UC Irvine's work from other research.
"[The gel] does more than just hold the wire together. It actually seems to make the metal oxide softer and more fracture-resistant. It increases the fracture toughness of this metal oxide that is doing the charge storage," Penner said.

The battery doesn't last longer.
The number of times it can be recharged before it dies is longer.
Until we reach a point where batteries can last for days instead of hours. Battery tech isn't going anywhere.

I hope this news will not quietly vanishes into oblivion to be never heared from again...
