Abstract: A Li-ion battery electrode piece, including an electrode piece substrate, a blank foil and an adhesive piece, the blank foil is arranged at one end of the electrode piece substrate along the length direction of the electrode piece substrate, one end of the blank foil away from the electrode piece substrate has a right-angle area, the adhesive piece is adhered at the right-angle area. The Li-ion battery electrode piece provided, through adhering an adhesive piece on the blank foil, avoids the end of the electrode piece from being deformed and folded, and improves the phenomenon of convex in battery core appearance and bad streak.
