ELECTRIC DOUBLE-LAYER CAPACITOR WITH CHEMICALLY MODIFIED CARBON NANO FIBER AS POLARIZED ELECTRODE

摘要

PROBLEM TO BE SOLVED: To provide an electric double-layer capacitor whose power storage capacity density is larger than a conventional electric double-layer capacitor. SOLUTION: A polarized electrode made of chemically modified carbon nano tube fiber is used. The electric double-layer capacitor using the chemically modified carbon nano tube fiber as the polarized electrode is approximately 1.3 times larger than that using carbon nano tube fiber as the polarized electrode, and is approximately 1.4 times larger than that using the activated carbon as the polarized electrode.
