Abstract
We studied the electrochemical phenomena and increase of capacity according to the polymer composite electrode of two different polymeric materials with different the voltage range and capacity. Polyaniline (PANI) with relatively high voltage and small capacity and poly [1,2] bis-thio[1,8]-naphthylidine (PTND) with slightly low voltage and large capacity were used as polymer composite electrode materials. After PTND was synthesized, PANI was synthesized on the surface of PTND. The synthesis and the fine structure were analyzed by FT-IR, XPS, FE-SEM, and FE-TEM. Charge/discharge capacity and cyclic voltammetry measurements were carried out for the electrochemical performance as a polymer cathode active material for lithium secondary batteries. The discharge capacities of PANI/PTND after 1,5, and 10 cycles at 1.3~4.0 V voltage range and room temperature 167 mAh/g, 90 mAh/g, and 81 mAh/g. When we compared with PANI (80, 67, and 62 mAh/g), the discharge capacity after 10 cycles was improved about 30%. After 50 cycles, the discharge capacity of PANI/PTND was 67 mAh/g.
