This invention discloses a method for preparing and applying phosphorus-doped sulfur nanoparticles. In these nanoparticles, phosphorus is uniformly distributed on the sulfur nanoparticles, forming S-P chemical bonds between them. Utilizing the properties that elemental phosphorus and sulfur are soluble and miscible in ethylenediamine solution, a solution of sulfur and phosphorus in a specific ratio is prepared and added to an organic solution containing a surfactant. A formic acid solution of a certain concentration is then added dropwise to precipitate the product. After washing and freeze-drying, the phosphorus-doped sulfur nanoparticles are obtained. This preparation method avoids high-temperature heating, directly forming P-S bonds through a wet chemical method to achieve phosphorus doping of sulfur. It boasts a high yield and can be mass-produced. The nano-sized phosphorus-doped sulfur particles, due to their excellent properties such as high specific surface area and nanoscale effect, can be applied in energy storage fields such as lithium-sulfur batteries, exhibiting excellent electrochemical performance.
