CONDUCTIVE CARBON, ELECTRODE MATERIAL INCLUDING SAID CONDUCTIVE CARBON, AND ELECTRODE USING SAID ELECTRODE MATERIAL |
摘要 |
Provided is conductive carbon that gives an electrical storage device having a high energy density. This conductive carbon includes a hydrophilic part, and the contained amount of the hydrophilic part is 10 mass % or more of the entire conductive carbon. When performing a rolling treatment on an active material layer including an active material particle and this conductive carbon formed on a current collector during manufacture of an electrode of an electric storage device, the pressure resulting from the rolling treatment causes this conductive carbon to spread in a paste-like form and increase in density. The active material particles approach each other, and the conductive carbon is pressed into gaps formed between adjacent active material particles, filling the gaps. As a result, the amount of active material per unit volume in the electrode obtained after the rolling treatment increases, and the electrode density increases. |
