When a device is connected to a battery, a reaction occurs that produces electrical energy. This is known as an electrochemical reaction. Italian physicist Count Alessandro Volta first discovered this process in 1799 when he created a simple battery from metal plates and brine-soaked cardboard or paper.
A nanowire is a nanostructure, with the diameter of the order of a nanometer (10 −9 m). Nanowires generally have a thickness or diameter of tens of nanometers or less and a variable length. At the nanowire scale, quantum mechanical effects are significant to the extent that nanowires are sometimes called ''quantum wires''.
Now scientists have discovered a new battery that is one step closer to this possibility using nanowire technology. They built a battery using nanowires, which will be recharged endlessly. Their findings were publishing in the American Chemical Society Scientific Review, which can be applied for use in computers, smartphones, cars, and spacecraft.
