  "textContent": "In a circumference direction of a roll core of a battery cell of a battery, a positive electrode tab is electrically connected to a positive electrode plate at a first location, and a negative electrode tab is electrically connected to a negative electrode plate at a second location, where a winding end of the positive electrode plate extends beyond a winding end of the negative electrode plate, and the first location is any location at which the positive electrode plate extends beyond the winding end of the negative electrode plate. A part of the positive electrode plate between the second location and the first location is a positive electrode extension section, at least an inner surface of the positive electrode extension section is passivated, and the inner surface is a surface of a side that is of the positive electrode extension section and that faces the negative electrode plate.",
