Impressive energy storage and delivery : A simple, cost‐effective, and potentially scalable technique is described for fabricating support‐ and additive‐free NiO/Ni nanocomposite electrodes (see picture) for electrochemical supercapacitors. Maximum performances of energy storage and delivery were simultaneously achieved by developing a slow‐charging and fast‐discharging procedure.
