  "textContent": "A secondary battery and an electric apparatus are disclosed. The secondary battery includes a negative electrode plate including a negative electrode current collector and a negative electrode film layer with a thickness of H; a first surface away from the negative electrode current collector; and a second surface opposite the first surface. A first region of the negative electrode film layer includes a first active material with a thickness range from the second surface of the negative electrode film layer to 0.3H. The first active material comprises a first silicon-based material, which comprises secondary particles formed by aggregation of primary particles. A second region of the negative electrode film layer comprises a second active material with a thickness range from the first surface of the negative electrode film layer to 0.3H.",
