| 摘要 |
This invention relates to an anode for a secondary battery capable of occluding and releasing lithium ions, the anode having a multi-layer structure comprising: a first layer containing carbon as a main component; and a second layer as a main component containing a lithium-occluding material film, the film capable of occluding lithium more than a theoretical lithium-occlusion capacity for carbon, as well as a secondary battery using the anode. This invention can provide a secondary battery with a substantially improved battery capacity in a range where the battery is actually used, while having a higher charge-discharge efficiency and good cycle properties.
