A novel graphene(GN)/carbon black(CB) binary conductive additive has been developed, which is characterized by a unique microstructure and excellent performance for lithium ion batteries (LIBs). It was fabricated using a hydrothermal process, followed by heat treatment. The introduction of CB particles prevents GN from agglomerating and hence improves the electronic conductivity of the resulting additive...
Fibrous carbon materials have a variety of dimensions and structures. However, these materials were earlier restricted for use as anode materials for lithium ion batteries due to their cost and performance. With the development of nanotechnology, some modified and new forms of carbon fibers have emerged, which show good performance as anode materials. This paper reviews recent domestic and foreign...
The International Forum on Graphene 2014 was held in the Graduate School at Shenzhen, Tsinghua University, Shenzhen, China from May 18 to 21, 2014. It was organised by the China Association for Science and Technology (CAST) with the support of the National Natural Science Foundation of China, the Chinese Materials Research Society, Shenzhen Science and Technology Association and the Science &...
Graphene oxide was synthesized from expanded graphite powder by a simple one-step oxidation method. A CuO/graphene composite was then obtained using a hydrothermal method. The samples were characterized using AFM, XRD, SEM, TEM and electrochemical measurements. Results show that CuO acts as a spacer to prevent the agglomeration of graphene sheets. The graphene formed a 3D conducting network for fast...
The preparation of self-assembled ordered mesoporous carbons (SA-OMCs) using a soft template method has many advantages, such as low cost, ease of preparation and control. In this paper, we review the development periods, the basic principles and preparation procedures with an emphasis on the control of morphology and multi-level pore structure of OMCs based on SA-OMCs. We suggest that further research...
The Tenth Cross-Strait Symposium on Carbon Materials was held in Baotou City, Inner Mongolia, PR China from August 1 to 4, 2012. It was hosted by Tsinghua University and Inner Mongolia University of Science & Technology. More than 60 cross-strait carbon scientists participated in the conference, and 31 presentations were given, including 15 keynote talks and 16 oral presentations. The presentations...
Oriented graphite/polymer composite sheets were prepared using natural, crystalline flake graphites as raw materials, polyvinyl butyral as binders, polyethylene glycol and dibutyl phthalate as plasticizers by a tape-casting method at room temperature. The dependences of the binder contents and the blade heights on the orientation of the composite sheets were studied, and the effect of the orientation...
