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)
