Free-standing graphene-based nanohybrid paper electrode as an anode for lithium-ion batteries

Abstract

In this study, a free-standing nanohybrid paper electrode (F-Nanohybs) was prepared using nitrogen-doped graphene-based nanosheets (N-GNSs) and mesoporous Mn3O4 nanoparticles (M-Mn3O4). N-GNSs had a thickness of ∼3 nm and a nitrogen content of 5.3%. M-Mn3O4 had a highly crystalline, mesoporous structure with surface area of 60 m2 g−1. F-Nanohybs electrodes were produced via simple vacuum filtration of a homogeneous dispersion of N-GNS and M-Mn3O4. The F-Nanohybs exhibited a good electrical conductivity (5.4 S cm−1), large specific surface area (151 m2 g−1), and a well-organized morphology. Thus, the F-Nanohybs displayed a high reversible capacity of (740 mA h g−1) at a current density of 100 mA g−1 and a stable performance over 100 consecutive charge/discharge cycles.
