摘要 |
Provided is a cell wherein out of electrodes constituting the cell, the outermost two electrodes are both cathodes, cathode current collectors of the cathodes are single-side coated with cathode active materials on the first surfaces thereof, other sides of cathode current collectors non-coated with cathode active materials are disposed toward the outside of a cell assembly and the thickness of cathode current collectors is 70 to 150% of that of the cathode active material coated layer. The cell in accordance with the present invention exhibits excellent safety in a nail penetration test. |
