Electrode for capacitor, process for producing same, and capacitor including the electrode

摘要

An electrode for capacitor includes a current collector having conductivity, a protective layer formed on the current collector, an anchor coat layer formed on the protective layer, and a polarizing electrode layer formed on the anchor coat layer. The protective layer contains an oxyhydroxide and the anchor coat layer contains conductive particles.

1. An electrode for capacitor, comprising:
a current collector having conductivity; a protective layer formed on the current collector and containing an oxyhydroxide; an anchor coat layer formed on the protective layer and containing conductive particles; and a polarizing electrode layer formed on the anchor coat layer, wherein at least a surface of the current collector is made of aluminum, the oxyhydroxide is represented by a composition formula AlXOY(OH)Z, where X, Y, and Z are any natural numbers, and a ratio D/C between a peak C indicating presence of Al2O3 and a peak D indicating presence of AlXOY(OH)Z in the protective layer ranges from 0.05 and 0.8, inclusive where the peaks can be obtained upon carrying out measurements on the protective layer by using Fourier transform infrared spectroscopy.
