Effect of Surface Modification on Properties of Positive Electrode Materials for Supercapacitors
The supercapacitor cathode material(NCS)was modified by using(methylferrocene)dodecyl dimethyl ammonium bromide surfactant.By testing the properties of NCS materials before and after modification,the influence of the change of NCS surface properties on the electrochemical properties of the materials was explored.The results showed that the charge and discharge time,charge transfer ability and ion diffusion rate of the modified NCS in cyclohexane solution were improved.The directional arrangement of surfactants improved the interfacial dynamics of NCS material and electrolyte,and the charge and discharge performance of the material was improved.This research is expected to provide exploratory ideas for other fields of electrochemical energy storage research and the improvement and exploration of supercapacitors,and has a wide range of application prospects.
