Problems solved by technology

However, in the ferrocene-based supercapacitors currently prepared by blending and doping, ferrocene is easy to sublimate and lose, resulting in low stability and service life, and if it is modified on the electrode by covalent bonds, the cost is high and The process is cumbersome, which limits its application as a pseudocapacitive electrode material

Abstract

The invention provides a manganese porphyrin compound, which is four-p-ferrocenyl undecyloxyphenyl manganese porphyrin, and its chemical structural formula is as follows: Four-p-ferrocenyl undecyloxyphenyl When manganese porphyrin compounds are used as electrode materials for supercapacitors, the synergistic effect of ferrocene groups and manganese porphyrin structural units makes them have excellent redox characteristics, fast charge and discharge, and good cycle stability, which can further improve Properties of manganese-based pseudocapacitors.

Description

technical field [0001] The invention relates to the technical field of supercapacitors, in particular to a manganese porphyrin compound, a preparation method and a supercapacitor for its application. Background technique [0002] Supercapacitors (SCs) are a new type of energy storage device that has developed rapidly in recent years. As a new type of high-power compensation and energy storage device, it has both fast charge and discharge capabilities, long cycle life and high safety. It is a key development object of high-efficiency energy storage devices and has broad application prospects in energy, communication, transportation, power electronics, national defense and other fields. Supercapacitors can be divided into electric double layer capacitors and pseudocapacitors. In general, pseudocapacitors have higher specific capacitance and energy density than EDLCs due to the presence of Faradaic reactions. [0003] Electrode materials are the main factors affecting the per...
