Ternary lithium battery pole piece capable of preventing winding breakage

The utility model discloses a ternary lithium battery pole piece capable of preventing winding breakage, which comprises a pole piece body, a first blank part is arranged on one surface of an initialwinding end of the pole piece body, which is in contact with a winding needle, a second blank part is arranged on the other surface of the initial winding end of the pole piece body, and the length ofthe first blank part is greater than that of the second blank part. At present, a ternary battery is prevented from being broken; that is to maintain low compaction, the pole piece is not too hard; however, the design cannot implement high-energy density design; according to the utility model, the blank of the pole piece body is specially designed, and the winding direction is limited, i.e., thefirst blank part is firstly contacted with the winding needle for winding, so that the pole piece can be wound without breaking under high compaction, the high-cost investment is not needed, the innermost winding ring can be ef
