| titleOfInvention | Lithium ion battery cathode material core-shell structure FeS2Preparation method of @ C nanoring |
| abstract | The invention relates to the technical field of nano anode materials, in particular to a preparation method of a high-performance lithium ion battery anode material, namely a core-shell structure FeS2@ C nanoring. The method comprises the step 1) of preparing alpha-Fe by adopting a hydrothermal method 2 O 3 A nano-ring particle; 2) prepared alpha-Fe by solution method 2 O 3 Coating organic layer to prepare alpha-Fe 2 O 3 @ RF nanoring particles; 3) for the prepared alpha-Fe 2 O 3 @ RF nanoring particles are heat-treated to carbonize organic matter to obtain Fe 3 O 4 @ C nanoring; 4) the obtained Fe 3 O 4 @ C is vulcanized to finally obtain FeS 2 @ C nanoring particles; 5) FeS to be obtained 2 And (5) manufacturing the @ C nano-ring particles into button cells, and carrying out electrochemical test. The invention has simple formula, simple operation, good repeatability and high product purity; the raw materials are rich and environment-friendly; the material has a regular structure and good stability; has a high capacity as an anode material. |
