Scientists at Stanford University have created supercapacitors from a combination of everyday paper and nanotechnology techniques, it has been reported.

Yi Cui, assistant professor of materials, science and engineering at the institution, told Stanford University News that the paper supercapacitor may last through 40,000 charge-discharge cycles, which is more than lithium batteries are capable of.

He explained to the publication that to create the product a sheet of paper is coated with ink made from nanotubes and silver nanowires, which makes the material capable of storing electric charge.

Mr Cui is quoted as saying: "Society really needs a low-cost, high-performance energy storage device, such as batteries and simple supercapacitors."

The news provider also stated that the electrically charged paper still works when it is crumpled up and suggested that it may be useful for electric or hybrid cars.

This month, AVX Corp released a range of high-voltage ceramic capacitors, which have been earmarked for use in the telecoms, military, aerospace and medical sectors.
