Anode for lithium metal polymer secondary battery comprising surface patterned anodic current collector and method of preparing the same |
摘要 |
There are provided an anode for a lithium metal polymer secondary battery comprising an anodic current collector having a surface on which a plurality of recesses having a predetermined shape are formed and a method of preparing the same. The plurality of recesses are formed on a surface of the anodic current collector using a physical method or a chemical method. In a lithium metal polymer secondary battery employing the anode, oxidation/reduction of lithium and the formation of dendrite occur only in the recesses formed by surface patterning of the anodic current collector. Thus, expanding and shrinking of a battery due to a change in the thickness of the lithium anode can be prevented and cycling stability and the lifespan of a battery can be improved.
