  "textContent": "An electrochemical device includes a packaging bag, an electrode assembly, and a binder. The electrode assembly is disposed in the packaging bag. The binder is configured to bond the electrode assembly to the packaging bag. The binder includes a first bonding layer, a substrate layer, and a second bonding layer that are stacked in sequence. The first bonding layer adheres to a surface of the electrode assembly. The second bonding layer adheres to a surface that is of the packaging bag and that is closer to the electrode assembly. A peel strength between the first bonding layer and the electrode assembly is Fi, a peel strength between the second bonding layer and the packaging bag is F2, and the peel strengths satisfy 50 N/m ≤ Fi ≤ 1000 N/m and 1 ≤ F1/F2 ≤ 10. A tensile strength of the substrate layer is 100 MPa to 2000 MPa.",
