  "textContent": "A single battery, a battery apparatus, and a power consumption apparatus are provided. The single battery includes a casing having an accommodating cavity and at least one winding core accommodated in the accommodating cavity. The winding core includes a positive electrode piece, a negative electrode piece, and a separator. After being laminated, the winding core is formed with flat surfaces opposite to each other and corner regions connected to two sides of the opposite flat surfaces. A distance between the flat surfaces opposite to each other is h. Four endpoints connecting the opposite flat surfaces and the corner regions and the opposite flat surfaces surround and form a middle region. The middle region has a rectangular structure. A length of the middle region in a winding direction is d, and a maximum thickness of each of the corner regions in the winding direction is a, where 0.015≤2a/dh≤0.1.",
