Published: January 2015

Li3VO4 nanoparticles embedded in graphene nanosheets (Li3VO4@GNS) were obtained using a sol-gel method. The composite presents excellent high-rate performance with a stable capacity of 133 mA h g(-1) at 50 C and long-life performance with a capacity retention rate of 63.1% after 5000 cycles at 5 C.

Materials Science and Engineering Program and Walker Department of Mechanical Engineering, The University of Texas at Austin, Austin, Texas 78712, United States.

With the increasing popularity of electric transportation over the past several years, fast-charging lithium-ion batteries are highly demanded for shortening electric vehicles' charging time. Extensive efforts have been made on material development and electrode engineering; however, few of them are scalable and cost-effective enough to be potentially incorporated into the current battery production. Here, we propose a facile magnetic templating method for preparing LiFePO (LFP) cathodes with vertically aligned graphene sheets to realize fast-charging properties at a practical loading of 20 mg cm.

Extrusion-based printing of macroscopic architectures layer-by-layer offers new opportunities for constructing customized electromagnetic interference (EMI) shielding materials. However, current research primarily focuses on improving the printability of material inks by increasing contents and adding various modifiers, controllable construction of ultralight and robust macro-architectures with structural design at both macro- and micro-scales is still challenging. Herein, we develop a graphene oxide foaming ink enriched with air bubbles for direct-ink writing, enabling the creation of macroscopic graphene architectures with arbitrary geometries.

Laboratory of Advanced Materials, Shanghai Key Lab of Molecular Catalysis and Innovative Materials, Academy for Engineering & Technology, Advanced Coatings Research Center of Ministry of Education of China, Fudan University, Shanghai 200438, P. R. China.

A porous hedgehog-like CoO/NiO/graphene oxide (denoted as PHCNO/GO) microsphere was prepared by a facile solvothermal method, followed by an annealing treatment under argon atmosphere. Benefiting from the thin CoO/NiO nanosheets with a large specific surface area, abundant pores distributed between the CoO/NiO nanosheets, and GO firmly wrapped around the surface of PHCNO microspheres, the PHCNO/GO microspheres showed excellent lithium storage performance. The CoO/NiO nanosheets provided numerous active sites, achieving a high reversible specific capacity.

The development of advanced bifunctional oxygen electrocatalysts for the oxygen reduction reactions (ORR) and oxygen evolution reactions (OER) is crucial for the practical application of zinc-air batteries (ZABs). Herein, porous carbon nanosheets integrated with abundant graphene-wrapped CoO and CoNx (CoO/CoNx-C) were successfully fabricated through a simple one-step pyrolysis. With convenient porous channel and large accessible surface, abundant CoO/CoNx species and graphene wrapping structure, CoO/CoNx-C exhibited a half-wave potential of 0.
