Pricinples of Battery (Lithium-ion)

Cathode (+Poly(vinylidene fluoride))

Separator

Electrolyte

Anode (+Poly(vinylidene fluoride))

Note!! There are still few disadvatages to overcome!

Nanocellulose as binder and separator (1/2)• Graphite + MFC in aqueous

solution

• High flexibility and low density

• Pood cycling performance but low conductivity

Jabbour et al. (2010)Wang et al. (2014)

Nanocellulose as binder and separator (2/2)

• Water should be removed to keep NFC structures as open as possible

• A Flexible, mechanically strong battery cell with good cycling properties

• Cells could be produced by using existing paper-making procedures!

Leijonmarck et al. (2013)

Conclusions and future propects

• There is potential to have a flexible, but still mechanically strong, and renewable batteries• Batteries can be produced with low-cost

by traditional methods• All in all, nanocellulose has many

promising properties, such as high surface area, flexibility, possibility to modification (electrochemical properties)
