For example, "graphite foam" is a material that has been investigated, both as a freestanding electrode material [60], as well as a support onto which materials may be coated [61, 62]. Graphite foam is produced by expanding the interlayer spacing of graphite, allowing for an increased surface area while maintaining high conductivity throughout.
Current collectors always play a vital role in battery and supercapacitor cells which bridges the electrons from active materials toward external devices. However, the second function of a current collector – as a substrate to cultivate the growth of active material – has always been overlooked and ignored.
