    摘要： The electrode of the present invention is provided with an active material-containing layer comprising as the structural material composite particles composed of an electrode active material, a conductive additive and a binder, and a current collector in electrical contact with the layer. The composite particles are formed by integrating the conductive additive and binder with the electrode active material particles. The active material-containing layer is formed by subjecting powder comprising at least the composite particles to pressurization treatment to form a sheet, and placing the sheet at the location of the current collector at which the active material-containing layer is to be formed. The electrode active material and conductive additive in the active material-containing layer are non-isolated and electrically linked. This construction allows an electrode with excellent electrical characteristics to be realized, which exhibits adequately reduced internal resistance and easily permits increased energy density to be achieved for electrochemical devices.

    摘要： Composite particles for an electrode of the invention are produced through a granulating step in which, a conductive additive and a binder are brought into a close contact with particles consisting of the electrode active material to integrate with each other. The granulating step preferably comprises a process for preparing a stock solution comprising the binder, the conductive additive and a solvent, a process for forming a fluidized bed by throwing particles of electrode active material into a fluidizing bathe and a process for bringing the particles of electrode active material and the particles of conductive additive into a close contact with the binder by spraying a stock solution into the fluidizing bathe, allowing the stock solution adhering to the particles of electrode active material and drying the same to remove the solvent from the adhered stock solution. Composite particles thus obtained are used as the constituent material for electrode, and further, the electrode is used as an anode and/or cathode of an electrochemical element; thereby, the internal resistance of electrode can be reduced satisfactorily and the power density of the electrochemical element can be increased satisfactorily.
