Abstract
Poly(2-chloroaniline-co-2-ethylaniline)-composite-Zn was synthesized by in situ chemical oxidative method using ammonium per sulphate as oxidant, HCl as dopant and linear alkyl benzene sulphonic acid (LABSA) as surfactant. The resulting copolymer composite was characterized by FTIR, and UV–Visible spectroscopic methods. The thermal stability was established using thermogravimetric analysis. The conduction mechanism was examined in terms of the dielectric constant and the electrical conductivity of 1.46 × 10–7 Scm−1 measured showed semiconducting nature. The oxidation/reduction potentials and electrochemical reaction of Li/copolymer cells were tested by cyclic voltammetric technique. Poly(2-chloroaniline-co-2-ethylaniline)-composite-Zn has been tested as anode in Li-ion batteries. The discharge and charge capacity of ~ 47 and ~ 14mAh/g at 1 to 5 cycles show good reversibility. This is a feasible value for using it as the positive electrode material in lithium ion secondary batteries.
