Facile preparation of monodisperse NiCo2O4 porous microcubes as a high capacity anode material for lithium ion batteries

Monodisperse NiCo₂O₄ porous microcubes were used as anode materials for lithium-ion batteries, and they exhibit outstanding rate capability and cycling stability.

Hierarchical NiCo2O4 Micro- and Nanostructures with Tunable Morphologies as Anode Materials for Lithium- and Sodium-Ion Batteries

NiCo₂O₄ microrods with open structures are successfully synthesized using a solvothermal method. Compared with those of dense microspheres, the one-dimensional (1D) porous microrods show much higher capacities and stability for both Li- and Na-ion batteries due to the 1D open structure facilitating fast ion transport and buffering volumetric change during charge/discharge. This work demonstrates that the electrochemical performance of NiCo₂O₄ is highly dependent on morphologies of the active material.

The design and synthesis of porous NiCo2O4 ellipsoids supported by flexile carbon nanotubes with enhanced lithium-storage properties for lithium-ion batteries

The as-prepared 3D porous NiCo₂O₄ ellipsoids supported by flexile carbon nanotubes nanowire arrays show high reversible capacity, excellent cycling stability, and good rate capability when used as an anode material for LIBs.

Design and synthesis of hollow NiCo2O4 nanoboxes as anodes for lithium-ion and sodium-ion batteries

This work is about the synthesis of hollow NiCo₂O₄ nanoboxes and their electrochemical performance for LIBs and SIBs.

Facile synthesis of three-dimensional NiCo2O4 with different morphology for supercapacitors

The morphology of NiCo₂O₄ can be controlled by changing the kinds of alkali source and the addition of NH₄F, influencing its electrochemical properties.
