They make a battery that looks like a sheet of paper at the Rensselaer Polytechnic Institute in New York.

The battery base is cellulose, with carbon nanotubes on one side and lithium metal on the other. Cellulose is impregnated in a lithium hexafluorophosphate solution. Thus, each side is an electrode, the solution provides electrolyte and the cellulose acts as a separator.

The battery is flexible, thin, can work at temperatures between 150 and 70 ° C, is cheap and not very toxic. Researchers hope to apply it to pacemakers, insulin pumps, mobile phones and laptops, among others.
