Abstract
The present invention relates to a preparation method of a carbon quantum dot/carbon coated VSecomposite material (VSe@CQD), and belongs to the technical field of electrode material of a potassium ion battery and preparation thereof. By compositing the carbon, carbon quantum dots and vanadium diselenide (VSe), the three components generate a synergistic effect. The carbon quantum dot/carbon coating can improve the electronic conductivity and lithium ion diffusion rate of the material, and also can inhibit the agglomeration of the vanadium diselenide (VSe). Therefore, the prepared carbon quantum dot/carbon coated VSecomposite material (VSe@CQD) has excellent electrochemical performance and excellent rate performance and cycle stability. The method is simple in process, low in cost, environment-friendly, and suitable for large-scale industrial production.
