Cellulose/graphite/carbon fibres composite electrodes for Li-ion batteries

Cellulose/CF electrodes display moderate specific capacity of 200 mA h g−1 and a good specific capacity retention at high current rate, whereas cellulose GP electrodes demonstrate high specific capacity of about 310 mA h g−1 and a low specific capacity retention at high current rate which is ascribed to the high binder content, i.e. 20%, and low electron conductivity of 100 S m−1. The use of CF/GP blends as active materials allows obtaining electrodes with high electron conductivity and specific capacity retention with CF:GP weight ratios ranging between 1:1 and 1:2.
