The advance of nickel-cobalt-sulfide as ultra-fast/high sodium storage materials: The influences of morphology structure, phase evolution and interface property

By tuning multi-factor functioning of both ether-based electrolyte and optimal voltage window, NiCo2S4 nanodots (~9 nm) homogeneously encapsulated in the N-doped carbon matrix are constructed to impart improvement on electrochemical properties.299
