Transparent and Flexible Battery for Power Generation and Storage at Once

DGIST research group in South Korea  developed single-layer graphene based multifunctional transparent devices  Various use of electronics and skin-attachable devices are expected with the development of transparent battery that can both generate and store power.The scientists in the Smart Textile Research Group developed film-type graphene based multifunctional transparent energy devices.

The team actively used ‘single-layered graphene film’ as electrodes in order to develop transparent devices. Due to its excellent electrical conductivity and light and thin characteristics, single-layered graphene  film is perfect for electronics that require batteries. By using high-molecule nano-mat that contains semisolid electrolyte, the research team succeeded in increasing transparency (maximum of 77.4%) to see landscape and letters clearly.

Furthermore, the researchers designed structure for electronic devices to be self-charging and storing by inserting energy storage panel inside the upper layer of power devices and energy conversion panel inside the lower panel. They even succeeded in manufacturing electronics with touch-sensing systems by adding a touch sensor right below the energy storage panel of the upper layer.

We decided to start this research because we were amazed by transparent smartphones appearing in movies. While there are still long ways to go for commercialization due to high production costs, we will do our best to advance this technology further as we made this success in the transparent energy storage field that has not had any visible research performances”, explains Changsoon Choi from the Smart Textile Research Group, and co-author of the paper published on the online edition of ACS Applied Materials & Interfaces.

The findings were also conducted as a joint research with various organisations such as Yonsei University, Hanyang University, and the Korea Institute of Industrial Technology (KITECH).
