Abstract
A flexible electrode comprises an activated cotton textile composite comprising activated carbon fibers, nickel sulfide nanoparticles and graphene and a process for making the flexible electrode. The process may comprise preparing a cotton textile containing Ni(NO3)2. Then, the cotton textile containing Ni(NO3)2 may be heated at a first temperature to produce an activated cotton textile composite comprising activated carbon fibers, nickel nanoparticles and graphene. The activated cotton textile composite may be then treated with sulfur to produce an activated cotton textile composite comprising activated carbon fibers, nickel sulfide nanoparticles and graphene. The nickel sulfide particles may be NiS2 nanoparticles in a form of nanobowls, and distributed on a surface and inside the activated carbon fibers. The activated carbon fibers and the nickel sulfide nanoparticles may be coated with graphene. Banana peels may be activated and treated with the similar processes to form electrodes for both supercapacitor and battery applications.
