Abstract
Effect of addition of poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) conducting polymer on the structure and properties of a cathode material based on lithium iron phosphate was studied. The X-ray diffraction method was used to examine the structure of lithium iron phosphate in a freshly prepared C-LiFePO4/C/PEDOTS:PSS composite material and in that subjected to a prolonged cycling. The chargedischarge characteristics of the cathode material of the conventional composition, which contains carbon black and poly(vinylidene fluoride) binder, and a new composition with addition of PEDOT:PSS were compared. The specific capacity of C-LiFePO4/C/PEDOT:PSS was 165 mA h g−1 (at 0.2C current), which substantially exceeds the specific capacity of the LiFePO4 material in the conventional composition.
