  • Patent number: 10847801
    Abstract: Provided is conductive carbon which gives an electric storage device having a high energy density. This conductive carbon is characterized in having a hydrophilic solid phase component, where the ratio of the peak area of an amorphous component band in the vicinity of 1510 cm?1 against the peak area in a range from 980 to 1780 cm?1 in a Raman spectrum of the hydrophilic solid phase component is within a range of 13 to 19%. When performing a rolling treatment on an active layer including an active 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 while covering the surface of the active particles, the conductive carbon being pressed into gaps formed between adjacent active particles and filling the gaps.
