Bendable power management can be possible with graphene nanosheets

South Korean scientists have concluded a form of bendable power sources running on graphene nanosheets. It a highly flexible material which can be rolled or moulded into a wearable device. So a user can carry the electronic devices with him wherever he would like to and he can even wear them. This amazing bendable power source design is the brainchild of Kisuk Kang from the Korea Advanced Institute of Science and Technology, Daejon, and his colleagues.

The developed power source is a graphene based hybrid electrode producing a flexible lithium rechargeable battery. The V2O5 Cathode material has been galvanized on graphene paper (coated in lithium that functions as anode) with pulsed laser deposition. The result is an ultralight and flexible enough power source which can be moulded or rolled. Kisuk Kang has said that “The performance of the new battery is promising. The electrode exhibits significantly improved electrochemical performance in almost all aspects of electrochemical properties, such as higher energy density, power density and better cycle life, compared with non-flexible conventional electrodes.”

Similarly, Scientists from University of Standford have also developed some paper thin batteries which were made up of carbon nanotubes and lithium compounds. But the bendable batteries of Kisuk Kang's team is being considered as more efficient power source. Presently, the South Korean researchers are planning to enhance the battery performance via a solid state or polymer electrolyte. We shall hope that the team would also find some ways to bend the hardware also for more flexibility.
