摘要
Abstract
The low conductivity and slow electrochemical kinetics of manganese-based oxide materials hinder the further development.At present,most research on its modification uses inorganic materials and involves complex synthesis steps.Porous manganese dioxide(MnO2)is synthesized using a simple condensation reflux method and is modified with poly(3,4-ethylenedioxythiophene)(PEDOT)to form a composite.Conductive polymers can improve the electrical conductivity of the electrode material,prevent direct contact of the active material with the electrolyte,and reduce the volume expansion of the electrode material during charging-discharging.The composite has good electrochemical performance.It has a specific discharge capacity of 624 mAh/g after 500 cycles at a rate of 0.25 C in 0.01-3.00 V.When the rate increases to 3.00 C,the specific discharge capacity is still keep at 314 mAh/g.关键词
