Nippon Chemi-Con Corporation is a Japanese corporation that produces electrolytic capacitors. Nippon Chemi-Con was founded in 1931 by Toshio Satoh as the first electrolytic capacitors production in Japan.Their capacitors are used in many motherboards including DFI, and PSUs from Zippy Technology and Seasonic. Currently they are considered one of the best capacitor makers, along with Hitachi, and their reputation is a selling point for top of the line PSU brands like PC Power and Cooling, Enermax, BFG Technologies, Sea Sonic, Antec, SilverStone Technology and others.Today Nippon Chemi-Con still dominates the Global Aluminum Electrolytic industry as the largest producer and is poised to expand their business and influence in the capacitor industry with their many new developments including Conductive Polymer Capacitors, Ultra-Capacitors and Ceramic Capacitors.

An electricity storage device includes an electricity storage element formed by winding an electrode body of an anode or cathode side along with a separator, an electrode leading section having an inclined edge is formed on an element end-face of the electricity storage element by a part of the electrode body.


The present invention aims at: providing an accelerated reaction in a liquid-phase reaction; forming, by way of the reaction, a metal oxide nanoparticle and carbon that carries the metal oxide nanoparticle in a highly dispersed state; and providing an electrode containing the carbon and an electrochemical device using the electrode. In order to solve the above-mentioned problem, shear stress and centrifugal force are applied to the reactant in the rotating reactor so that an accelerated chemical reaction is attained in the course of the reaction. Further, the carbon carrying a metal oxide nanoparticle in a highly dispersed state comprises: a metal oxide nanoparticle produced by the accelerated chemical reaction, wherein shear stress and centrifugal force are applied to a reactant in a rotating reactor in the course of the reaction; and carbon dispersed in the rotating reactor by applying shear stress and centrifugal force. An electrochemical device produced by using the carbon carrying the metal oxide nanoparticle as an electrode has high output and high capacity characteristics.
