LG Chem cable batteries may reshape mobile designs

(Phys.org)—LG Chem says it has a cable-type lithium-ion battery that is so flexible it can be tied in knots and worn as a bracelet or woven into textiles. For mobile device designers, the eventual commercial production ...

Graphene battery demonstrated to power an LED

(PhysOrg.com) -- Scientists in Hong Kong have reported, in ArXiv, their experiments to make a graphene battery that they say generates an electrical current by drawing on the ambient thermal energy in the solution in which ...

Making a light-harvesting antenna from scratch

(PhysOrg.com) -- Sometimes when people talk about solar energy, they tacitly assume that we're stuck with some version of the silicon solar cell and its technical and cost limitations. Not so.

Scientists find simple way to produce graphene

(PhysOrg.com) -- Scientists at Northern Illinois University say they have discovered a simple method for producing high yields of graphene, a highly touted carbon nanostructure that some believe could replace silicon as the ...
