| 摘要 |
The present invention relates to an electrode collector, an anode having an active material layer on the electrode collector while the active material layer is coated with tubular tartar or the tubular tartar is coated on the surface of polymer, a manufacturing method thereof, and a lithium battery comprising the same. The anode comprising tartar as an active material layer in a nanoscale tubular form, expands the tartar active material evenly, and the expanded volume can be absorbed into the inner space of the tube, which can improve a cycle property degradation of the battery due to a mechanical fatigue. In addition, the charging and discharging time can be reduced by the lithium ion moving in and out of the nanotube at the same time. |
