Abstract

When butyl rubber dissolved in toluene was used as a binder of carbon powder, carbon paste showed a mechanical hardness due to the fast volatility of the solvent just after the electrode fabrication. With a view of validating its quantitative electrochemical behaviors, its kinetic parameters, e.g. the symmetry factor, the exchange current density, the capacity of the double layer, the Michaelis constant, the time constant and other factors were investigated. Our experimental facts indicated that butyl rubber is available for a promising binder of carbon powder.
