PANI/MnOC生物质碳基电极材料的制备及电化学性能研究.

Polyaniline (PANI) structure will collapse after continuous charging and discharging, leading to the problem of poor cyclic stability. In this paper, aniline is polymerized in situ on the surface of biomass carbon (MnOC) material by in situ polymerization technology, and PANI particles are controlled to grow orderly on the surface of MnOC. The prepared PANI/MnOC composite electrode material has the characteristics of both double-layer capacitance and Faraday pseudocapacitance. The analysis and test results show that the PANI/ MnOC composite electrode material consists of a porous network of micropores, mesoporous and macropores, which is conducive to charge storage and transmission. Ry measu ring its electrochemical performance, it is found that compared with pure PANI, the specific capacitance of PANI/MnOC composite elect rode material is 385.0 F/g when the current density is 1.0 A/g, which is higher than the specific capacitance of pure PANI. When the current density is 2.0 A/g and the current density is 5000 cycles continuously, the capacitance retention rate of composite electrode material reaches 82.2%. [ABSTRACT FROM AUTHOR]
