AI Technical Summary
Existing technologies struggle to achieve a synergistic solution between high specific surface area, reasonable hierarchical pore size, high tap density, and excellent processability in supercapacitor electrode materials, and traditional preparation methods present environmental problems and processing challenges.
A method for preparing modified capacitor carbon using asphalt/resin composite coating was adopted. The activated carbon surface was uniformly coated by fluidized bed spraying to form a coating layer. Combined with the soft template method and CO2 activation method, a hierarchical pore structure of micropore-mesopore-macropore was constructed during the carbonization and activation treatment stages.
A capacitor carbon material with both high specific surface area and high tap density was prepared, which improved the electrode processability and electrochemical performance, reduced production costs and simplified the processing procedures, making it suitable for industrial production.
