An Accidently Invented Battery Can Last up to 400 years

The researchers assume that the gel lets the metal oxide in the battery to plasticize, giving its nanowires new-found versatility and durability to the battery.

Researchers from the University of California: have unexpectedly created a battery that can continue for 200,000 cycles of recharging and can last up to 400 times longer. This invention could lead us nearer to batteries that can be charged thousands of times, without the necessity for any replacement.

The primary idea of the research was to build a solid-state battery by displacing the traditional liquid in the lithium batteries including a very thick electrolyte gel, according to their study written in the journal ACS Energy Letters. They also replaced the lithium in the batteries with gold nano wires for electric storage.

The UCI nano battery was examined in test circumstances over a three month period, offering a “94-96% average Coulomb efficiency,” according to the researchers. No need of space or power and fracturing of any nano wires was reported by the test.

Thai said:

The coated electrode holds its shape much better, making it a more reliable option. This research proves that a nano wire-based battery electrode can have a long lifetime and that we can make these kinds of batteries a reality.

UCI doctoral applicant Mya Le Thai was the one who made the incidental discovery a fact when she painted a set of gold nano wires in manganese dioxide, then used a, “Plexiglas-like,” electrolyte gel. These nano wires normally degrade after short use, as their fragility makes them crack as charge and discharge loads. Still, when the researchers at UCI examined Mya’s versions, they saw they were nearly fully intact and available for further use.

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,

If newly discovered technology is utilized to present consumer electronics, it can build a battery that can last 400 times larger than the common lithium batteries. However, the UCI nano battery is noiseless in its development stage, and it will be noiseless be a long time before it is made commercially accessible. However, once it is free, it could make the main distinction between computers, smartphones, and appliances in the market in terms of giving power to the devices.

The study was directed in coordination with the Nano structures for Electrical Energy Storage Energy Frontier Research Center at the University of Maryland, with funding from the Basic Energy Sciences division of the U.S. Department of Energy.
