Carbonized antimony phosphate (C@SbPO₄) has been synthesized and the charge storage performances as an anode for both Li and Na-ion batteries have been investigated. For better understanding the role of the synthesis route on the charge storage behavior, SbPO₄ was investigated using the sol-gel and electrospun process. The as-prepared materials exhibited a layered structure in both processes which were confirmed from the X-ray diffraction analysis. The percentage of the carbon coating on the core structure of SbPO₄ was estimated using thermogravimetric analysis. The graphitic nature of the carbon-coating was analyzed via Raman spectra. Spherical morphology of the as-prepared samples and the carbon-coated fibrous samples was obtained using FESEM analysis. It was observed that the SbPO₄/C delivered a specific capacity of 548 mAh g⁻¹ at 5 A g⁻¹ with an excellent round trip efficiency of as an anode in a LIB application. On the other hand, in the case of SIB, it delivered an initial specific capacity of 397 mAh g⁻¹ at 1 A g⁻¹. Both SIB and LIB showed long-term cycle stability of around 300 and 500 with an excellent capacity retention of 88.6% and 92.8% respectively. The obtained performance characteristics have also compared with the bare SbPO₄ and the C@SbPO₄ prepared using the sol-gel process and electrospun. Thus, the obtained electrospun C@SbPO₄ showed superior performance and can be used as a potential candidate for both Li and Na analogs as anode materials.

合成了碳化磷酸锑（C @ SbPO ₄），并研究了作为锂离子电池和钠离子电池负极的电荷存储性能。为了更好地理解合成路线对电荷存储行为的作用，使用溶胶-凝胶和电纺丝工艺对SbPO ₄进行了研究。由X射线衍射分析证实，所制备的材料在两种方法中均显示出层状结构。SbPO ₄核心结构上的碳涂层百分比使用热重分析法估算。碳涂层的石墨性质通过拉曼光谱分析。使用FESEM分析获得了所制备样品和碳包覆纤维样品的球形形态。可以观察到，SbPO ₄ / C在5 A g ^-1下的比容量为548 mAh g ^-1，在LIB应用中作为阳极具有出色的往返效率。在另一方面，在SIB的情况下，派送的397毫安g的初始比容量^-1 1 A G ^-1。SIB和LIB均显示出约300和500的长期循环稳定性，分别具有88.6％和92.8％的出色容量保持率。所获得的性能特征还与使用溶胶-凝胶法和电纺丝制备的裸露SbPO ₄和C @ SbPO ₄进行了比较。因此，所获得的电纺丝的C @ SbPO ₄显示出优异的性能，并且可以用作Li和Na类似物作为阳极材料的潜在候选者。
