Nano-aggregates of cobalt nickel oxysulfide (CoNi)OxSy have been synthesized by hydrothermal processing and exhibited specific and areal capacitance as high as 592 F g−1 and 1628 mF cm−2, respectively, at a current density of 0.5 A g−1/1.375 mA cm−2. They also show high capacitance retention upon extended cycling at high rates.
