An electrode for electric double-layer capacitor includes a collector with a protective layer containing phosphorous on its surface, and a polarizable electrode layer that is formed on this collector and can adsorb and desorb ions. An amount of a phosphorous compound per unit surface area of the collector, eluted when the collector is immersed into water, is not greater than 1.35 mg/min terms of phosphorous equivalent. An electric double-layer capacitor employs this electrode for at least one of a positive electrode and a negative electrode.

Electric double-layer capacitor and electrode therefor

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.

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

Disclosed is an electrochemical capacitor which comprises an element, an electrolyte, and an outer case that houses the element and the electrolyte. The element comprises: a negative electrode that is obtained by forming a negative electrode layer on the surface of a collector, the negative electrode layer containing a carbon material in which lithium ions are absorbed; a positive electrode that is obtained by forming a positive electrode layer on the surface of a collector, the positive electrode layer absorbing ions; and a separator that is interposed between the negative electrode and the positive electrode. The electrolyte contains lithium ions. A coating film that contains lithium carbonate is formed on the surface of the carbon material that is contained in the negative electrode layer.
