Ion-doped and carbon-coated dual-modified NVPOF electrode material synthesized under assistance of surfactant and preparation method thereof

The invention belongs to the technical field of preparation of electrode materials, and particularly relates to an ion-doped and carbon-coated dual-modified NVPOF electrode material synthesized under the assistance of a surfactant and a preparation method of the ion-doped and carbon-coated dual-modified NVPOF electrode material. According to the invention, a co-precipitation technology is adopted, an ion-doped and carbon-coated dual-modified NVPOF electrode material synthesized with the assistance of a surfactant is utilized, and the material is composed of a small disc which is formed by self-assembling two-dimensional nanosheets along a z axis and has a diameter of about 1 [mu] m and a thickness of about 200 nm; due to the unique morphological characteristics, a higher specific surface area and more active sites can be provided for embedding and de-embedding of sodium ions, so that the specific capacity of the material is improved. 本发明属于电极材料制备技术领域，具体涉及一种利用表面活性剂辅助合成的离子掺杂和碳包覆双重改性NVPOF电极材料及其制备方法。本发明采用共沉淀技术，利用表
