改进的石墨电池材料
A Splash Of Graphene Improves Battery Materials
— Researchers would like to develop lithium-ion batteries using titanium dioxide, an inexpensive material. But titanium dioxide on its own doesn't perform well enough to replace the expensive, rare-earth metals or fire-prone carbon-based materials used in today's lithium-ion batteries.
To test whether graphene, a good conductor on its own, can help, Pacific Northwest National Laboratory's Gary Yang and colleagues added graphene, sheets made up of single carbon atoms, to titanium dioxide.
When they compared how well the new combination of electrode materials charged and discharged electric current, the electrodes containing graphene outperformed the standard titanium dioxide by up to three times. Graphene also performed better as an additive than carbon nanotubes.
Yang will discuss this work and provide an overview of the field of electrical storage materials at this year's Micro Nano Breakthrough Conference in Portland, Oregon (see: http://oregonstate.edu/conferences/MNBC/).
Graphene 溅改善电池材料
—研究员想要使用钛二氧化物，廉宜的材料发展锂－离子的电池。但是钛二氧化物靠它自己不很好地，足够运行代替昂贵、稀有地球金属或者被用于今天的锂－离子电池的容易火的以碳为基础的材料。
测试是否 graphene，一个好领导者靠它自己，能帮助，太平洋西北的国立实验室盖瑞杨和同事把 graphene ，由单一碳原子组成的床单，加入钛二氧化物。
当他们比较了电极材料的新组合索取并且释放电流有多好，包含 graphene 的电极赢过了标准钛二氧化物被在到上面三次。Graphene 也更好地运行当做一个添加剂胜于碳纳米管。
杨将会在波特兰，奥勒冈州的今年微十亿分之一突破会议中讨论这一个工作而且提供电储藏材料的领域的概观。（见到： http ：||oregonstate.edu│会议│MNBC│)
