University of California, Irvine researchers were just trying to create better nanowires as a substitute for normal rechargeable batteries when they accidentally developed a rechargeable battery that could last up to 400 years.
Nanowires are fragile and tend to give up after several charges but Nanowires are also good conductors because they contain a lot of surface area to hold electrons.
This is the reason why the team of PhD Student Mya Le Thai was researching the substances of nanowires made from gold that is enclosed in a special electrolyte gel…
In a series of tests, the team made a staggering discovery: The battery survived for 200,000 charge cycles in just three months without losing any performance. This battery could also potentially power an ordinary smartphone and laptop for 400 years.
“That was crazy”, said Reginald Penner, the leader of the chemistry faculty of the University. “Usually these Batteries decline rapidly after only five or six thousand cycles, seven thousand at the most.”…
The scientists are still not sure why the combination of the gold wires and gel makes a super battery. But since gold is an expensive material, the researchers are trying out some few alternatives before they start generating a marketable product. This is why we still don’t know if we can use these for our smartphones, but these first test certainly looks promising (source).
