A doctoral student discovered a nano-battery that could last up to 400 years through over 200,000 charge/discharge cycles. The student was experimenting with gold nanowires for battery use but found they would break down over multiple cycles. By coating the wires in manganese dioxide and an electrolyte gel, the battery survived over 30,000 cycles in initial testing. If mass produced, the battery could extend laptop batteries to over 400 years by replacing current lithium-ion batteries that typically last 300-500 cycles. The researchers suggest using nickel instead of gold for affordability in mass production.

After playing around in the university’s lab, it was doctoral student Mya Le Thai who
initially made the discovery, one which could lead to rechargeable batteries that last
up to 400 years. This means longer-lasting laptops and smartphones, and fewer
lithium-ion batteries accumulating in landfills.

Originally, the researchers were experimenting with nanowires for potential use in
batteries, but found that over time, the fragile, thin wires would break down and crack
after multiple charging cycles. It was on a whim that Thai coated a set of gold
nanowires in manganese dioxide and a Plexiglas-like electrolyte gel.

“She started to cycle these gel capacitors, and that’s when we got the surprise,” said
chair of the university’s chemistry department, Reginald Penner. “She said, ‘this
thing has been cycling 10,000 cycles and it’s still going.’ She came back a few days
later and said ‘it’s been cycling for 30,000 cycles.’ That kept going on for a month.”

Thai’s breakthrough is incredible, considering the average laptop battery lasts 300 to
500 charging cycles. The nano-battery developed at UCI survived 200,000 cycles in
three months, meaning it could extend the life of the average laptop battery by about
400 years.

Of course, the researchers realized the amount of gold nanowire needed to create
this battery would drive up prices, so they suggested nickel could be a substitute for
mass production.

Either way: not bad for messing around in a laboratory.
