Embodiment 1
[0026] The high-performance lithium-sulfur battery cathode material is a porous flower-like CoP / C@S composite material.
[0027] The preparation method of the high-performance lithium-sulfur battery cathode material comprises the following steps:
[0028] (1) Preparation of flower-like cobalt chloride bismethanol nanosheet precursor:
[0029] 0.5~1gCoCl 2 ·6H 2 O was dissolved in a mixture of 30mL methanol and 10mL N,N-dimethylformamide to form a transparent solution; then, under continuous stirring, 5mmoL urea was added to the transparent solution to form a homogeneous system; then the obtained homogeneous system was transferred Put it into a 50mL polytetrafluoroethylene-lined stainless steel autoclave, seal it and keep it heated at 150°C for 12h, then cool to room temperature; after centrifugal precipitation, wash the powdery precipitate with distilled water and ethanol; finally wash the powdery precipitate Dry in an oven at 60°C for 6 hours;
[0030] (2) Preparation of ...
