| titleOfInvention | Preparation method of nano high-entropy oxide and lithium ion battery negative electrode material |
| abstract | The invention discloses a preparation method of a nanometer high-entropy oxide and a lithium ion battery cathode material, wherein iron oxide is usedMixing titanium oxide, magnesium oxide, zinc oxide and copper oxide powder according to the stoichiometric ratio of equimolar metal atoms, and carrying out ball milling, cold briquetting, high-temperature sintering and ball milling again to obtain the high-entropy oxide (FeTiMgZnCu) 3 O 4 . And then according to the mass percent of each component: (FeTiMgZnCu) 3 O 4 70% of nano powder, 20% of acetylene black and 10% of binder. The invention adopts a high-temperature solid-phase method to synthesize the high-entropy oxide (FeTiMgZnCu) in one step 3 O 4 The block material is further processed by high-energy ball milling to obtain nanometer material (FeTiMgZnCu) with sheet structure 3 O 4 Powder, simple operation process, low cost and no pollution. The invention utilizes said high entropy oxide (FeTiMgZnCu) 3 O 4 The prepared lithium ion battery negative electrode material can keep higher specific capacity under the charge-discharge current density of 100mA/g and has excellent cycling stability. |
