PAPEL

microfibrille

Environmentally high quality Li-ion-Paper Battery

The PAPEL battery is flexible, ecological and economic. It could meet the production requirements of small stationary and roaming units up to larger scale products such as electric vehicles and renewable energy power stations.
Polymer electrodes are replaced by paper electrodes, toxic solvent is removed and the fluorinated binder is replaced by cellulose fibers and microfibrils.
As a result of an aqueous filtration procedure and the use of materials of plant origin, the majority of the toxic and inactive components are removed, thus reducing cost and recycling problems.

» Description and functionalities

Electrodes in nanostructured cellulose microfibrils surrounding graphite (anode) or LiFePO4 (cathode) plates.

» Technology

Water-based filtration procedure
Paper from the standard paper industry

» Performances

- The discharge capacity of the anode and cathode reaches the nominal values for the active materials used (performances comparable to those obtained with standard binders and production procedures).
- The bio-sourced binder provides the electrode with great flexibility (self-supporting) so that it can withstand stress of between 60 and 450 MPa
- Exploitation of the paper industry
- Possible to recycle the electrodes with a process in an aqueous medium.

To date, Li-ion batteries have a high energy density, longer service life and provide additional safety. However, for use in large-scale products, it is necessary to reduce production costs and minimize the environmental impact. The PAPEL battery provides this via the substitution of fluorinated binders with cellulose, the substitution of toxic organic solvents with water and the use of a manufacturing procedure for electrodes from the paper industry with high production capacity.
