In the academic laboratories of the University of California, a team of scientists has developed an “eternal” nanobattery that can operate for four centuries.
This unique battery has been rigorously tested and has demonstrated potential that surpasses current energy solutions. The nanobattery prototype successfully withstood two hundred thousand charge and discharge cycles, which is several hundred times longer than the lifespan of conventional lithium-ion batteries used in our gadgets.
The President of the University of California, Michael Drake, shared his impressions: “The experiment showed that the capacitors do not wear out, and the battery itself does not lose power or capacity. Nanowires do not break either.”
And here is the main secret of this innovative device: the nanowires that make up this nanobattery are made of the precious metal gold. They are coated with manganese dioxide and gel, which promotes efficient current transmission. It's important to note that this battery remains flexible during charging and does not deform, which is a problem with conventional lithium-ion batteries.
However, despite its potential advantages, creating such a nanobattery is still very expensive. Its high cost makes it not yet available for mass production and use in gadgets.
