Abstract
Due to their unique structure and excellent physical and chemical properties, carbon nanotubes show great application potential in the field of electrochemistry. The purpose of this study is to systematically explore the electrochemical properties of carbon nanotubes and their application in energy storage and conversion. It adopts the method of combining experimental and theoretical calculation to analyze the different types of carbon nanotubes, and explore their performance in the fields of electrocatalysis, supercapacitors and lithium ion batteries. It is found that the functionalized and modified carbon nanotubes have higher electrochemical activity and stability, which can significantly improve the specific capacity and cycle life of the electrode material. Especially in oxygen reduction reactions, nitrogen-doped carbon nanotubes exhibit catalytic activity comparable to noble me tal catalysts, providing a new idea for the development of low-cost and high-performance electrocatalysts. In addition, the electrochemical properties of carbon nanotubes can be further optimized, such as when combined with me tal oxides for supercapacitors, showing excellent energy density and power density.
