Abstract: A winding type battery cell includes a roll core and at least one electrode sheet unit. The roll core includes a positive connection part, a negative connection part and an insulation part located between the positive connection part and the negative connection part. The positive connection part and the negative connection part are respectively connected with two ends of the insulation part. The electrode sheet unit includes a positive electrode sheet, a negative electrode sheet and a separator. The positive electrode sheet and the negative electrode sheet are separated by the separator. The positive electrode sheet is connected with the positive connection part, and the negative electrode sheet is connected with the negative connection part. The winding type battery cell is formed by winding the electrode sheet unit around the roll core. A winding battery with the winding type battery cell is also provided.
