石墨烯在锂电池负极材料的应用
锂电池负极材料的主要种类有天然石墨(59%),人造石墨(30%),中间相炭微球(8%)及其他类型(3%)。石墨类负极材料仍然占据锂电负极材料的主流地位,但近年新型负极材料(如钛酸锂等、石墨烯)等的研发与应用也开始受到业内关注。
石墨烯是一种新型材料,其创始研究人员获得2010年诺贝尔化学奖。将石墨烯应用于锂离子电池负极材料中,可以大幅度提高负极材料的电容量和大倍率充放电性能。
国内北京化工大学等高校和研究机构进行了石墨烯材料的研究工作。企业也开始推进石墨烯负极材料的产业化进程。2011年11月,常州第六元素材料科技股份有限公司成立,将生产用于锂电池负极材料的石墨烯,计划在2012年将产量提升到吨级。2012年4月,大连丽昌新材料有限公司建成了全自动石墨烯负极材料生产线,年产能达300吨。
2012中国锂电负极材料研讨会将于8月23-25在山东青岛召开,来自北京化工大学的专家将出席会议,并做题为“石墨烯用作锂离子电池负极材料的电化学性能研究”的大会报告。

Graphene & Its Applications in LIB Anode Materials
The LIB anode material mainly includes Natural Graphite (59%), Artificial Graphite (30%), Mesocarbon Microbeads (8%) and other types (3%). The graphite based material still occupy the mainstream of the LIB anode materials; while in recent years, the R&D of novel anode materials (such as lithium titanate, graphene) are concerned by the industry.
Graphene is a novel material; its original finders won the 2010 Nobel Prize in Chemistry. Graphene used in LIB anode material, the electric capacity and high rate charge and discharge performance can be significantly improved.
In China, Beijing University of Chemical Technology and other institutions have started the studies of graphene materials. Enterprises have also begun to promote the industrialization process of the graphene anode material. In November 2011, the Sixth Element Material Technology Co., Ltd was set up in Changzhou, Jiangsu Province, which will produce the LIB anode material used graphene. The company planned to produce about 1t graphene products in 2012. In April 2012, Dalian Greentech Advanced Materials Co. Ltd built a automatic production line of graphene anode materials, the capacity is 300 t/a.
2012 China LIB Anode Materials Conference will be held in August 23-25 in Qingdao, Shandong Province. The expert from Beijing University of Chemical Technology will deliver a presentation on "The Study of Graphene as a Lithium-Ion Battery Anode Material”
