Report summary
In recent years, flexible wearable electronic products have made rapid development, which puts forward higher requirements for the flexibility of battery electrode materials. However, the bending resistance of common powdered electrode materials is generally poor when they are prepared by slurry stirring and coating (aluminum or copper foil collecting fluid). In order to solve this problem, the flexible three-dimensional conductive carbon network can be prepared as a general template collecting fluid, and then the electrode materials meeting the needs can be obtained by composite materials with high specific capacity. Based on the above ideas, we studied the combined pyrolysis of oxygen and ammonia of cellulose, successfully prepared three-dimensional conductive carbon network with high specific surface area, high conductivity, low density and excellent flexibility, and prepared sandwich electrode by self-assembly method. This electrode was used in the negative electrode of lithium-ion battery, overcoming the volume effect, showing good cycle stability and times Rate performance. In addition, the three-dimensional conductive carbon fiber network prepared by electrospinning method was used in the electrode materials of lithium-ion batteries and lithium sulfur batteries, and good results were obtained.
