| titleOfInvention | Negative plate, lithium ion battery and preparation method thereof |
| abstract | The invention discloses a negative plate, comprising a negative current collector and a negative electrode coating coated on the negative current collector, wherein the negative electrode coating comprises a negative active material, a conductive agent and a bonding agent, and the negative active material comprises carbon coated lithium titanate particles which have a spinel structure. According to the invention, the negative active material of the negative plate comprises carbon coated lithium titanate, there is no change of the crystal form of the spinel lithium titanate in the process of intercalation/deintercalation of lithium ions, the crystal lattice constant has small change, and the volume change is less than 1%; when the negative plate is applied in a lithium ion battery, compared with a traditional lithium ion battery which comprises a graphite material as a negative active material, the battery cycle performance is better. The invention further provides a lithium ion battery which utilizes the negative plate and a preparation method thereof. |
