Ready-to-use binder-free Co(OH) plates@porous rGO layers/Ni foam electrode for high-performance supercapacitors.

In this work, an outstanding nano-structured composite electrode is fabricated through the co-deposition of Co(OH) nanoplates and porous reduced GO (p-rGO) nanosheets onto Ni foam (NF). Through field emission scanning electron microscopy and transmission electron microscopy observations, it was confirmed that porous reduced graphene oxide sheets are completely wrapped by uniform hexagonal Co(OH) plates. Due to the unique architecture of both components of the prepared composite, a high surface area of 234.
