Flexible, transparent monolayer graphene device for power generation and storage

Nanowerk  May 8, 2019
Researchers in North Korea adapted a single-layer graphene (SLG) as an electrode for the supercapacitor, touch sensor, and a triboelectric nanogenerator (TENG), thus making an electronic system that is ultrathin, lightweight, transparent, and flexible. Capacitive-type transparent and flexible electronic devices can be simultaneously used as an electrochemical double-layer capacitance-based supercapacitor and as a sensitive, fast-responding touch sensor in a single-device architecture by inserting a separator of polyvinyl alcohol–lithium chloride-soaked polyacrylonitrile electrospun mat on polyethylene naphthalate between two symmetric SLG film electrodes. They successfully demonstrated the device…read more. TECHNICAL ARTICLE
