Abstract

Poly(carbon disulfide) was studied by cyclic voltammetry using glassy carbon and platinum macro- and microdisk electrodes. The electron transfer kinetic is significantly faster at glassy carbon electrodes than at Pt electrodes. It is chemically reversible with moderate electron transfer rates. Voltammetric results of poly(carbon disulfide) are in good agreement with our battery testing data. The k0 value measured at a Pt microdisk electrode is 7×10−3 cm/sec. Electrochemical data suggest that PCS can be a potential cathode material for low current density lithium batteries.
