Three-dimensional hierarchical ZnCo₂O₄@C₃N₄-B nanoflowers as high-performance anode materials for lithium-ion batteries.

ABSTRACT: ZnCo₂O₄ has become one of the most widely used anode materials due to its good specific capacity, cost-efficiency, high thermal stability and environmental benignity. However, its poor conductivity and cycle stability have limited its practical application in lithium-ion batteries. To overcome these issues, we constructed a 3D nanoflower composite material (ZnCo₂O₄@C₃N₄-B) by combining ZnCo₂O₄ as a framework and B-doped g-C₃N₄ (g-C₃N₄-B) as a new carbon source material via a simple hydrothermal method. ZnCo₂O₄@C₃N₄-B exhibited exceptional specific capacitance of 919.76 mA h g^-1 after 500 cycles at 0
