Rapid identification of P–C bonds in phosphorus–carbon anode materials

Phosphorus-carbon composites in alkali metal-ion batteries benefit from P-C bonds, enhancing stability and performance. Rapid P-C bond detection is crucial. X-ray photoelectron spectroscopy (XPS), balancing convenience and accuracy, was chosen in this study for its efficiency in analyzing P-C bond energies, aiding in the quick identification of these bonds in phosphorus-carbon anodes.
