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 溅改进电池资料
—研究员想要运用钛二氧化物，廉宜的资料开展锂－离子的电池。可是钛二氧化物靠它自己不很好地，满足运转替代贵重、稀有地球金属或许被用于今日的锂－离子电池的简单火的以碳为根底的资料。
测验是否 graphene，一个好领导者靠它自己，能协助，太平洋西北的国立实验室盖瑞杨和搭档把 graphene ，由单一碳原子组成的床布，参加钛二氧化物。
当他们比较了电极资料的新组合讨取并且开释电流有多好，包括 graphene 的电极赢过了规范钛二氧化物被在到上面三次。Graphene 也更好地运转作为一个添加剂胜于碳纳米管。
杨将会在波特兰，奥勒冈州的本年微十亿分之一打破会议中评论这一个作业并且提供电贮藏资料的范畴的概观。（见到： http ：||oregonstate.edu│会议│MNBC│)
