Supercapacitors to replace batteries?
https://www.electronics-lab.com/supercapacitors-to-replace-batteries/
by Martin Cooke @ elektormagazine.com: It was reported last year that researchers at Rice University in the US, led by chemist James Tour had developed a method of producing a form of graphene on commercial polyimide plastic sheet by zapping it with a laser. The process is called LIG (Laser Induced Graphene). The resulting graphene layer […]
