Reaction Steps

First, 2.0 g of DMcT powder was dissolved in 7.0 g of NMP. To the resultant solution further added was 9.7 g of NMP to give a DMcT-NMP solution with a color of greenish blue. To the DMcT-NMP solution added were 0.5 g of acetylene black powder and 0.5 g of metallic copper powder with an average particle size of 1 μm to be homogeneously dispersed. In the thus obtained solution dissolved was 1.0 g of powder of undoped reduced polyaniline with a conductivity of 10-8S/cm and an RDI value of 0.25, which was obtained by undoping polyaniline ("ANILEAD" available from Nitto Denko Corp., Japan) in an alkaline solution and reducing the resultant with hydrazine. To the resultant solution further added was a solution obtained by dissolving 0.5 g of polyvinyl pyrrolidone with an average molecular weight of 25,000 in 2.5 g of NMP to give black ink. The black ink was applied on a titanium foil with a thickness of 30 μm by using an applicator with a coating gap of 250 μm. The resultant foil was heated at a temperature of 80° C. for 15 minutes in an argon gas stream and further heated in a vacuum at a temperature of 80° C. for 60 minutes, thereby producing a composite electrode with a thickness of 50 μm. This electrode was cut into a square of 2×2 cm, which was designated as a composite electrode F.
