回个贴表示支持一下吧，感激不尽。谢谢。 (Reuters) - Scientists in the United States have developed a paint that can store and deliver electrical power just like a battery. Traditional lithium-ion batteries power most portable electronics. They are already pretty compact but limited to rectangular or cylindrical blocks. Researchers at Rice University in Houston, Texas, have come up with a technique to break down each element of the traditional battery and incorporate it into a liquid that can be spray-painted in layers on virtually any surface. "This means traditional packaging for batteries has given way to a much more flexible approach that allows all kinds of new design and integration possibilities for storage devices," said Pulickel Ajayan, who leads the team on the project. The rechargeable battery is made from spray-painted layers, with each representing the components of a traditional battery: two current collectors, a cathode, an anode and a polymer separator in the middle. The paint layers were airbrushed onto ceramics, glass and stainless steel, and on diverse shapes such as the curved surface of a ceramic mug, to test how well they bond. One limitation of the technology is in the use of difficult-to-handle liquid electrolytes and the need for a dry and oxygen-free environment when making the new device. The researchers are looking for components that would allow construction in the open air for a more efficient production process and greater commercial viability. Neelam Singh, who worked on the project, believes the technology could be integrated with solar cells to give any surface a stand-alone energy capture and storage capability. The researchers tested the device using nine bathroom tiles coated with the paint and connected to each other. When they were charged, the batteries powered a set of light-emitting diodes for six hours, providing a steady 2.4 volts. The results of the study were published on Thursday in the journal Nature Scientific Reports. via:http://www.reuters.com/article/2012/06/28/us-science-batteries-paint-idusbre85r13l20120628 srep00481.pdf[ Last edited by justinzhao on 2012-6-30 at 13:46 ] |

关于Scientific Reports期刊：网上整理： Nature 集团在2011年夏天创办Open Access期刊“Scientific Reports”。这是Nature集团对“开放存取”的尝试。目前已经接受投稿。 该期刊在线发行，没有看到出版印刷版的消息。 领域包括：biology, chemistry, physics 和earth sciences. Scientific Reports is: Fast — rapid review and publication Rigorous — peer review by at least one member of the academic community Open — articles are freely available to all and authors retain copyright Visible — enhanced browsing and searching to ensure your article is noticed Interlinked — to and from relevant articles across nature.com Global — housed on nature.com with worldwide media coverage 网址：www.nature.com/scientificreports. 要到2013年才有IF，现在已被web of science收录了多个文章，涵盖各个方向的文章。 Nature 旗下的，但是这个杂志说来奇怪，没有像新的在线杂志nature communication一样前面有个Nature 大名，总体来说还是很不错的，目前来看比advanced material要强一些 |
