| 摘要 |
The invention provides a cathode material for lithium ion secondary battery which has high charge-discharge capacity, favorable circulating characteristic and fast charge-discharge velocity, producing method thereof, and lithium ion secondary battery using the cathode material for lithium ion secondary battery. The inventive cathode material 10 for lithium ion secondary battery is characterized in that the cathode material 10 for lithium ion secondary battery is a material forming a cathode active substance 2 formed by dispersing Sn and Ag in the amorphous carbon, on the cathode current collector 1, the amorphous carbon content of the cathode active substance 2 is more than 50at%, and the ratio of Sn content and Ag content is from 0.5 to 4. |
