NEGATIVE ACTIVE MATERIALS, LITHIUM ION BATTERIES, AND METHODS THEREOF |
摘要 |
Methods of preparing negative active materials and negative active materials are provided herein. The preparation methods include: A) mixing a carbon material, an organic polymer, a Sn-containing compound—optionally with water—to obtain a mixed solution system; B) adding a complexing agent into the mixed solution system obtained in step A optionally while stirring to form an intermediate solution; C) adding a reducing agent into the intermediate solution obtained in step B to a reaction product; D) optionally filtering, washing and then drying the reaction product to obtain the negative active material.
