摘要：

The influence upon electrochemical characteristics of the alkyl chain length of poly(3-alkylthiophene) for use as electrode active materials of secondary batteries has been investigated by cyclic voltammetry, charge-discharge tests, and chronoamperometry. Redox potentials observed in both the cyclic voltammetry and the charge-discharge tests have been found to be dependent on the alkyl chain length, as well as redox reaction rate determined in the chronoamperometry. These dependencies are discussed on the basis of the steric effects of the alkyl groups on the higher-order structure along the poly(thiophene) main chain. © 1990 The Japan Society of Applied Physics.
