In this study, we report results of succinic acid and polyethylene glycol (PEG) additives at different rates in mass (the rates of %0 - %200.) The structure and electrochemical properties of the LiFePO4/C were characterized by XRD, SEM, and galvanostatic charge-discharge measurements. Among the materials studied, the sample (A) which contains %100 succinic acid and %200 PEG (w/w), exhibits a 150mAhg-1 discharge capacity and it is corresponding to 88% of the theoretical capacity. The improved electrochemical properties were attributed to the reduced particle size and enhanced electrical contacts by carbon. © 2012 American Institute of Physics.
