| titleOfInvention | Lithium manganese silicate type positive electrode material of lithium ion battery and preparation method thereof |
| abstract | The present invention relates to a kind of lithium manganese silicate type positive electrode material of lithium ion battery and preparation method thereof; Described positive electrode is the Li with hollow ball shell Rotating fieldsn 2 mnSiOn 4 / C composite.During preparation, containing in the supersaturation Aqueous Lithium Salts of lithium salts deposit seed, add soluble manganese salt, obtain lithium salts-manganese salt solid particle after stirring, filtration, drying, the weight ratio of described lithium salts, manganese salt is 2: 1; By lithium salts-manganese salt solid particle and silicon source be by weight 3: 1 mix after, mix with carbon source, 500 ~ 900 DEG C of obtained solid particles of calcining under inert atmosphere, pickling, removes unreacted lithium salts and manganese salt, filters, dry.Invention increases Lin 2 mnSiOn 4 the ion of material, electronic conductivity, increase the contact area with electrolyte, and its actual specific discharge capacity can reach more than 300mAh/g, still can remain on more than 150mAh/g, be with a wide range of applications after 20 circulations. |
