SHEET-SHAPED COMPOSITE, MANUFACTURING PROCESS THEREFOR, AND ELECTRODE AND ELECTROCHEMICAL ELEMENT, USING THIS SHEET-SHAPED COMPOSITE

摘要

The present invention relates to a sheet composite of a metal compound and a fibrous carbon that can yield an electrode or an electrochemical element which achieves output property and high energy density, as well as a manufacturing method thereof. Sheer stress and centrifugal force are applied to a solution comprising a starting material metal compound and a fibrous carbon and reacted in a rotating reaction container to produce a composite material of metal compound and fibrous carbon. The composite material and a binder which is a fibrous carbon are stirred to produce a mixed solvent. The mixed solvent is subjected to suction filtration and vacuum drying. This mixed solution is molded in a paper machine to prepare a sheet composite. The fibrous carbon is carbon nanotubes having a specific surface area of 600 to 2600 m 2 /g.
