Cobalt silicate (Co2SiO4, denoted as CoSi) with a high theoretical capacity is deemed to be one of the sustainable electrode materials for SCs. However, its achieved electrochemical properties are still not satisfying. Herein, the phosphorus (P)-doped cobalt silicate, denoted as PCoSi, is synthesized by a calcining strategy. The PCoSi exhibits 1D nanobelts with a specific surface area of 46 m2∙g-1, and it can significantly improve the electrochemical properties of CoSi. As a supercapacitor's (SC's) electrode, the specific capacitance of PCoSi attains 434 F∙g-1 at 0.5 A∙g-1, which is much higher than the value of CoSi (244 F∙g-1 at 0.5 A∙g-1).
