Self-assembled synthesis of waxberry-like open hollow NiCo2S4 with enhanced capacitance for high-performance hybrid asymmetric supercapacitors

Rational designing microstructure of electrode materials has been regarded as an effective solution for boosting the electrochemical activity. To improve the electrochemical performance of NiCo2S4 for asymmetric supercapacitors (ASCs), a three-dimensional waxberry-like open hollow NiCo2S4 is designed and fabricated via self-assembly by a facile two-step hydrothermal path. The waxberry-like open hollow architecture with rough surface and...
