摘要：
A superior electrochemical performance of Co3O4 anode with water-soluble binder consisting of a combination of intrinsically conducting polymer poly-3,4-ethylenedioxythiophene:polystyrene sulfonate (PEDOT:PSS) dispersion and carboxymethyl cellulose (CMC) is presented. This type of electrode material shows ultrahigh capacity value of 1200 mA.h.g(-1). It also demonstrates an excellent stability during continuous cycling at 0.2 C (capacity loss is near 4-5%) and has no significant capacity fading at high current densities. Cyclic voltammetry measurements show that Co3O4-electrode containing conducting polymer has smaller changes in shape of the curves than in the case of anode material where polyvinylidene fluoride (PVDF) binder was used.
