| titleOfInvention | Composite lithium battery positive electrode material and preparation method thereof, lithium battery positive electrode and lithium battery |
| abstract | The invention relates to the technical field of lithium batteries, and discloses a composite lithium battery anode material and a preparation method thereof, a lithium battery anode and a lithium battery, wherein the preparation method of the composite lithium battery anode material comprises the following steps: (1) reacting metal cations with ligands to generate metal complexes, uniformly mixing the metal complexes with gel factors in a solvent, and aging to obtain composite gel; (2) calcining the composite gel in inert gas to obtain a calcined product; (3) carrying out hydrothermal reaction on a lithium source, a ferrophosphorus source and a calcined product under a water-containing condition to obtain a composite lithium battery cathode material; wherein the metal cation is Fe 2+ 、Fe 3+ 、Co 2+ 、Ni 2+ 、Mn 2+ 、Cu 2+ 、Zn 2+ 、Mo 2+ At least one of; the composite lithium battery positive electrode material contains the composite skeleton with the porous structure, so that the volume expansion of the electrode material in the charging and discharging process can be effectively improved, and the coulombic efficiency and the cycling stability of the battery can be improved. |
