| titleOfInvention | Preparation method of carbon cladding modified lithium manganate anode material |
| abstract | The invention relates to a preparation method of a carbon cladding modified lithium manganate anode material. The preparation method is characterized by comprising the following steps of: (1) adding lithium manganate into de-ionized water; (2) adding a soluble organic carbon source which accounts for 10-30% of the mass of lithium manganate into the obtained mixed solution; then adding a carbonizing catalyst which accounts for 0.5-5% of the mass of the soluble organic carbon source; (3) spraying and granulating the obtained mixed solution through a spraying drying machine; and (4) adding lithium manganate powder into a crucible, sintering at 300-450 DEG C for 0.5-4 hours and then cooling to obtain the product. According to the preparation method disclosed by the invention, the situation that a lithium manganate crystal form is damaged by high-temperature carbonization is avoided, and metal is reduced and separated out. The electrode conductivity is effectively improved, the surface chemical performance of an active material is improved and an electrode is prevented from directly contacting an electrolyte solution, so that the better circulating service life can be obtained. |
