Abstract
This work introduces the results of characterizing free-standing reduced graphene oxide paper, given its potential use as an electrode material in lithium-ion cells. Mildly reduced graphene oxide paper underwent further thermal reduction steps. The structural and chemical properties of the obtained materials were determined using Raman and Fourier-transform infrared spectroscopies and elemental combustion analysis. The morphology and thickness were determined with scanning electron microscopy imaging. This paper also reveals electrical and electrochemical properties of the material. The conductivity of the material obtained at 800 °C reached ≈70 S/cm, and the discharge capacity reached ≈160 mAh/g at 100 mA/g current density.
