Microfibrillated cellulose–graphite nanocomposites for highly flexible paper-like Li-ion battery electrodes

Microfibrillated cellulose nanoparticles were used as binders for the aqueous processing of flexible electrodes for Li-ion batteries. Microfibrillated cellulose formed a nanostructured web-like network around graphite platelets conferring to the graphite anode a highly porous structure, excellent flexibility and good cycling performances. This work demonstrates that microfibrillated cellulose can be effectively used as a binder element for the manufacturing of self-standing and flexible electrodes using a straightforward water evaporation process.
