paper battery

Paper batteries are batteries that are cellulose-based in combination with carbon nanotubes(CNTs). Since hardly any environmentally harmful chemicals are used in the batteries, paper batteries can be composted and disposed of in an environmentally friendly manner.

Paper batteries are rechargeable, extremely thin and flexible, and can be cut and shaped for special applications. They can be used wherever tiny amounts of energy are needed to power miniature electronic components, implants, active sensors or active tags.

In terms of structure, the two outer layers of a paper battery consist of two electrodes made of carbon nanotubes (CNTs). One electrode, the anode, is coated with a thin layer of lithium titanium oxide( LTO), while the other, the cathode, is coated with a layer of lithium cobalt oxide (LCO). Between these two layers, which are only a few micrometers thick, is a paper layer. For implanted paper batteries, blood or body sweat can be used as the electrolyte.
