This study investigates the impact of integrating g-CN into CuCoO electrodes on electrochemical performance working as binder-free electrodes. Flower-like CuCoO nanostructures on nickel foam are decorated with few-layer g-CN using a secondary hydrothermal process. The hierarchical g-CN/CuCoO nanoflower electrode demonstrates a specific capacity of 247.5 mA h g at a current density of 1 A g, while maintaining a capacity of 87.0 mA h g at a heightened current density of 5 A g. Notably, this electrode exhibited remarkable durability, retaining 98% of its capacity after 1000 cycles. The g-CN/CuCoO heterostructure shows promise for high-performance energy storage devices.
本研究调查了将g-CN集成到CuCoO电极中对其作为无粘结剂电极的电化学性能的影响。采用二次水热法在泡沫镍上的花状CuCoO纳米结构上装饰了几层g-CN。分层的g-CN/CuCoO纳米花电极在电流密度为1 A g时的比容量为247.5 mA h g，而在电流密度提高到5 A g时仍保持87.0 mA h g的容量。值得注意的是，该电极表现出显著的耐久性，在1000次循环后仍保留其容量的98%。g-CN/CuCoO异质结构在高性能储能器件方面具有潜力。
