| titleOfInvention | Silicon-based @ titanium niobium oxide core-shell structure anode material and preparation method thereof |
| abstract | The invention relates to the technical field of lithium ion batteries, and provides a silicon-based @ titanium niobium oxide core-shell structure cathode material and a preparation method thereof, wherein a titanium source and a niobium source are used as coating layer raw materials, the titanium source and the niobium source are prepared into a nano suspension through a sand mill, and then nano-micron-sized silicon-based particles are uniformly dispersed in the suspension; and then granulating by a low-temperature rapid drying technology, and finally forging at a specific high temperature to obtain the silicon-based negative electrode material coated with the nano titanium niobium oxide, which has good particle appearance and uniform particle size distribution. The titanium niobium oxide is used as a coating layer, and on one hand, the titanium niobium oxide has higher capacity; on the other hand, the coating layer can inhibit the volume expansion of the silicon-based material caused in lithium ion deintercalation, and can prevent silicon-based particles from directly contacting with electrolyte, thereby being beneficial to forming a stable SEI film and improving the first effect, the multiplying power and the cycling stability of the material; the method is environment-friendly, pollution-free, simple and easy to implement and can be industrialized. |
