Chinese scientists have successfully developed a super capacitor with better energy capacity using nitrogen and graphene-like carbon.
"We are able to make carbon a much better super capacitor," Xinhua quoted Huang Fuqiang, a material chemist at the the Shanghai Institute of Ceramics, as saying on Saturday.
The new material will enable electric vehicles travel 35 km after charging for just seven seconds, said the research team from the institute.
Details of the research were published in the latest issue of the journal Science.
