abstract = {Herein, a mesoporous MnCo2O4/Co3O4 nanocomposite was
fabricated using a polyvinylpyrrolidone (PVP)-assisted
hydrothermal synthesis method by maintaining only the
non-stoichiometric ratio of Mn and Co (2 : 6), leading
to an extra phase of Co3O4 coupled with MnCo2O4.
Microstructural analysis showed that the obtained sample has
a uniform nanowire-like morphology composed of
interconnected nanoparticles. The stoichiometric ratio
(2 : 4) was maintained to synthesize pure MnCo2O4 for
comparative analysis. However, the obtained structure of
pure MnCo2O4 was found to be irregular and fragile. After
their employment as anode-active materials, the
nanocomposite electrode showed superior high rate capability
(1043.8 mA h g−1 at 5C) and long-term cycling stability
(773.6 mA h g−1 after 500 cycles at 0.5C) in comparison to
the pure MnCo2O4 electrode (771.5 mA h g−1 at 5C and 638.9
mA h g−1 at 0.5C after 500 cycles). It was believed that
the extra phase of Co3O4 may also participate in the
electrochemical reactions due to its high electrochemically
active nature. Benefiting from the appealing architectural
features and striking synergistic effect, the integrated
MnCo2O4/Co3O4 nanocomposite anode exhibits excellent
electrochemical properties and high cycle stability for
LIBs.},
