NEGATIVE ELECTRODE AND NONAQUEOUS SECONDARY BATTERY USING THE SAME |
摘要 |
<P>PROBLEM TO BE SOLVED: To provide a negative electrode and a nonaqueous secondary battery using the negative electrode improving charge receiving property at the negative electrode from the viewpoint of battery design and causing little degradation of capacity by cycle repetition even to the charge of about 8-hour rate. <P>SOLUTION: This negative electrode for the nonaqueous secondary battery is formed by molding a negative electrode material formed of polycyclic aromatic hydrocarbon obtained by thermally reacting a raw material mainly composed of at least pitch, and a conductive material using a binder. I. The element ratio of hydrogen/carbon in the polycyclic aromatic hydrocarbon is in a range of 0.50 to 0.05, and the specific surface area of the negative electrode material by a BET method is in a range of 0.1 to 50 m<SP>2</SP>/g. II. The surface density of the negative electrode material is 6 mg/cm<SP>2</SP>or less. <P>COPYRIGHT: (C)2004,JPO |
