Printing of electronic devices on a paper substrate using 2D graphene-based ink is an opening gate to innovative applications, where devices would be biodegradable, eco-friendly and can be disposed of with negligible impact on the environment.
A highly flexible graphene paper assembled from graphene nanoplatelets and graphene oxides is fabricated and shows high electrochemical performance as a Li-ion battery anode.
We demonstrate the operation of a graphene-passivated on-chip porous silicon material as a high rate lithium battery anode with over 50X power density, and 100X energy density improvement compared to identically prepared on-chip supercapacitors.
