  "textContent": "A negative electrode plate and a preparation method and application thereof. The negative electrode plate includes a current collector and a composite active material layer disposed on at least one surface of the current collector. The composite active material layer includes a first and a second active material layers disposed sequentially on a surface of the current collector. The second active material layer is disposed on a surface of the first active material layer away from the current collector. The first active material layer includes a first binder. The first binder includes a low-swelling binder. The second active material layer includes a second binder. The second binder includes at least one of a high-swelling binder, an acrylic acid derivative multi-component copolymer. The low-swelling binder has a volume swelling ratio of 25% to 40%, and the high-swelling binder has a volume swelling ratio of 60% to 85%.",
