Dense Graphene Monolith Oxygen Cathodes for Ultrahigh Volumetric Energy Densities Energy Storage Materials, Available online 10 June 2017, Pages Lei Qin, Dengyun Zhai, Wei Lv, Wei Wei, Wei Yu, Yu Lei, Wei Yang, Jiaqiang Huang, Shanshan Yao, Jiang Cui, Feiyu Kang, Jang-Kyo Kim, Quan-Hong Yang
Graphical abstractThe dense yet porous graphene-based material is fabricated via three-dimensional densification of graphene hydrogel and using a sacrificial pore former (SiO2) on the dense graphene monolith. The bimodal pores with diameters ranging 1–6nm and 40nm created in the graphene-based monolith facilitate ion transport and oxygen diffusion, while providing sufficient space to accommodate the discharge products. Benefiting from a developed pore structure and robust microstructure, it delivers an unprecedented volumetric energy density with excellent long-term stability for Li-O2 batteries.

Graphical abstractThe three-dimensional (3D) hybrid aerogels built from graphene and polypyrrole-derived nitrogen-doped carbon nanotubes (G-NCNTs) are synthesized by facile hydrothermal and heat treatment process using graphite oxide (GO) and polypyrrole nanotubes (PNTs) as precursors. The 3D G-NCNTs hybrid aerogels, in which the NCNTs are dispersed homogeneously in the graphene sheets, are designed to efficiently support Pt nanoparticles. Comparing with 3D graphene (GA), the 3D G-NCNTs supported Pt-based catalyst possesses improved electrocatalysis activity and stability toward methanol oxidation reaction (MOR). The enhanced electrochemical performance is ascribed to the synergistic effect of GA and NCNTs.Image 1
