' ... While the new battery would still need to be recharged, the big difference is it would keep working efficiently over 200,000 charge cycles - which is pretty much a lifetime of use when it comes to devices such as phones, computers, cars, and even spacecraft. And it's a whole lot longer than the lifespand of today's lithium batteries. ...'

'... 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.
While the technology promises consumer electronics that last 400 times longer, this initial test platform isn't a true battery. Batteries have an anode, which allows electricity into the system, and a cathode, which outputs electricity. Instead of having both, the researchers linked together two cathodes that alternate charging each other. The continuous cycling from cathode to cathode makes a perfect system to test repeated recharging.
Penner says that it's like pouring water back and forth between two cups. After a few hundred transfers from one cup to the other, some water will usually spill out, leaving less "charge." That's a normal battery. Penner's system transferred the "water" between the "cups" 200,000 times, only losing about 5 percent.
