NiO-Co 3 O 4 nanoplate composite as efficient anode in Li-ion battery

“…[31] The same group also synthesized ternary core/shell nanowire arrays of Co 3 O 4 /NiO/C on the nickel foam via a three-step solution method. [32] The Co 3 O 4 /NiO/C core/shell nanowire arrays exhibited specific capacity of 1053 mA h g -1 at 0.5 C, which is higher than that of the pure Co 3 O 4 nanowire array film (724 mA h g -1 ) and NiO nanoflake film (454 mA h g -1 ). In this work, we develop a simple hydrothermal method to synthesize the 2D/0D (NiO/Co 3 O 4 ) hybrid nanocomposite.…”

“…NiO and Co 3 O 4 have also been selected to construct the hybrid nanocomposite, [30][31][32][33] due to their high theoretical capacities (718 mA h g -1 for NiO, and 890 mA h g -1 for [34][35][36][37][38] which exhibited a capacity of ~600 mA h g -1 at 400 mA g -1 after 15 cycles, much higher than pure Co 3 O 4 nanosheets (~150 mA h g -1 ). [30] Huang and co-worker reported a synthesis of aligned nickel-cobalt oxide nanosheet arrays on nickel foam substrates by means of chemical bath deposition technique, which delivered a capacity of 480 mA h g -1 and 430 mA h g -1 at 0.5 A g -1 and 1.0 A g -1 after 50 cycles, respectively.…”

Silver–nickel oxide core–shell nanoflower arrays as high-performance anode for lithium-ion batteries

“…Therefore, various NiO nanostructures as nanosheets [9][10][11][12][13], nanorods [14][15][16], nanocones [17], nanofibers [18][19][20][21], nanowires [22], nanowalls [23][24][25], and nanotubes [26,27] have been synthesized and investigated as anode materials of lithium-ion batteries. However, the conductivity of the nanostructured electrodes remains an important issue to be solved [28].…”

Rational design of metal oxide nanocomposite anodes for advanced lithium ion batteries

“…Additionally, Wu et al designed ternary core/shell structure of Co 3 O 4 /NiO/C nanowire arrays as high performance anode material for LIBs. The enhanced electrochemical properties are mainly ascribed to the core/shell nanowire architecture with potential synergistic contribution such as the improved mechanical stability [10]. Despite that there is some improvements regarding electrochemical performance for these reported metal oxide composites as compared to single metal oxide, the integrity maintenance of the metal-oxide composite electrode is still unsatisfactory by the fact that the morphology of cycled electrode has greatly changed from the pristine one [10,15,16,22e24].…”
