The Journal of Physical Chemistry C Vol. 120, № 30. P. 16453-16458Abstract: We report here a low-temperature method for the growth of self-organized nanoscale nickel-based particles with high energy storage properties. The Ni balls covered with highly porous NiO/NiOH thin shells are shown to form in an amine solution. High specific surface area (SBET = 56 m2/g) and crystallinity (Scherrer size = 28 ± 0.5 nm) made it possible to achieve a specific capacity of 2742 F/g at a scanning rate of 2 mV/s, which is higher in terms of mass of a surfactant layer than previously reported for other chemical approaches. In addition, an operating stability of at least 5000 cycles for electrodes produced on the basis of the synthesized particles is proved
