Co3S4 ultrathin nanosheets entangled on N-doped amorphous carbon coated carbon nanotubes with C S bonding for high performance Li-ion batteries

Cobalt sulfides are promising electrode materials for lithium ion batteries due to its high theoretical capacity. However, the disadvantages of low conductivity, poor cyclability combined with the large structural variation severely hinder its practical application. In this work, Co3S4 nanosheets on N doped amorphous carbon coated carbon nanotubes ([email protected]@Co3S4) are designed and fabricated, where the carbon nanotubes penetrate through...
