Flexible batteries

We talked about flexible batteries for years, but a team of Korean researchers have presented a new solution for flexible energy sources is not only more powerful than standard batteries lithium ion, but also potentially less expensive to produce than their predecessors malleable - and not surprisingly, the favorite topic around the world wonder, graphene is the heart of innovation. The rechargeable battery includes a cathode of vanadium oxide grown on a sheet of graphene, a separator is not identified, and a lithium anode coated graphene. According to the people behind the new source of energy, sports higher energy and power density and life cycle better than the stiff competition from the letter. Similar progress has also overcome rigid lithium ion batteries, but have joined carbon nanotubes, a material more expensive to produce than the graphene.

Of course, like all technological advances, we will not see these things for years or even decades, so you might as well get used to Ye Olde flagship.
