Chemists have manufactured a nanowire-based battery, which can be recharged thousands of times

Chemists have built a battery using nanowires, which can be recharged hundreds of thousands of times, bringing us closer to a battery that will not require replacement.

This important breakthrough, described in a new study, published in the American Chemical Society Scientific Review, could lead to long-life commercial batteries for use in computers, smart phones, home appliances, cars and even spacecraft.

Scientists have long tried to use nanowires in batteries. Thousands of times thinner than a human hair, nanowires are extremely conductive and have a large surface for electron storage and transport. However, these nanowires are extremely fragile and do not stand well in repeated discharges and recharges or circles. In a typical lithium-ion battery, it dilates event leading to cracks.

Researchers have now solved this problem by overlaying a gold nano wire in a manganese dioxide shell and then placing it on an electrolyte made of a plexiglass thickener. The researchers then tested the electrode in tests up to 200,000 times within three months without detecting any loss of nano-cell capacity or energy, as well as any breakage.

“The coated electrode retains its shape a lot better, making it a more reliable choice,” the study said. “This research demonstrates that a battery based on nanowires can last a long life and that we can make these kinds of batteries a reality.”
