  "textContent": "A cell including an electrode assembly, and the electrode assembly being formed by winding a positive electrode plate, a separator, and a negative electrode plate stacked. A negative active material of the negative electrode plate includes a silicon-based material, and two surfaces of the negative current collector are completely coated with the negative active material. At a first straight section, a first corner section, and a second straight section of an innermost turn of the positive electrode plate, two surfaces of the positive current collector are coated with a positive active material. An innermost turn of the negative electrode plate includes a third straight section, a second corner section, and a fourth straight section. The first straight section is located between the third straight section and the fourth straight section, and the third straight section is located between the first straight section and the second straight section.",
