The electrochemical properties of LiMn2O4 (LMO) based cathode material with conducting polymer binder containing poly-3,4-ethylenedioxythiophene/polystyrene sulfonate (PEDOT:PSS) dispersion and carboxymethylcellulose (СМС) were investigated for electrodes of three different thicknesses. The effect o...
