CELL ELECTRODE, SECONDARY CELL USING THE CELL ELECTRODE, AND METHOD FOR MANUFACTURING THE CELL ELECTRODE

摘要

This electrode uses a carbon fiber whose crystallites are 13 to 17 angstrom thick according to X-ray diffractometry. In a method for manufacturing the cell electrode using the carbon fiber, the carbon fiber is burned at a temperature between 900 DEG C and 1,330 DEG C. It is possible to provide a secondary cell having the characteristics of the carbon fiber and a high discharging capacitance.
