From the BBC:

Batteries made from plain copier paper could make for future energy storage that is truly paper thin.

The approach relies on the use of carbon nanotubes - tiny cylinders of carbon - to collect electric charge.

While small-scale nanotube batteries have been demonstrated before, the plain paper approach lends itself to making larger devices more cheaply.

The work, published in Proceedings of the National Academy of Sciences, could lead to "paintable" energy storage.
