Some US scientists are on the verge to revolutionize any electric-powered devices that rely on batteries, as they came up with a method that boosts the recharging capacity to the sky.
The world needs energy to be put into motion and a lot of it. Our lives are hovering around all sorts of electric-powered objects that are heavily relying on rechargeable batteries, from computers, smartphones to, very soon, cars. But not matter the technology used, these energy storage units have a limited lifespan and are rapidly losing their efficiency. However, we might finally get a breakthrough, as the University of California, Irvine researchers have invented a nanowire-based battery material that can be recharged almost indefinitely, moving closer to a battery that would never need to be replaced.
Nanowires, thousands of times thinner than a human hair, are highly conductive and feature a large surface area for the storage and transfer of electrons. However, they also come with a big disadvantage, as filaments are extremely fragile and do not hold up well to repeated discharging and recharging cycles.
The scientists claimed that they solved this issue by coating a gold nanowire in a manganese dioxide shell and inclosing it in an electrolyte made of a Plexiglas-like gel that is supposed to be failure free. UCI performed 200,000 recharging cycle tests over three months without detecting any loss of capacity or power. Therefore, these batteries are very close to become a reality if further tests conclude with similar results.
