  "textContent": "A battery, an electrochemical device containing same, and an electronic device are provided. The battery includes an electrode assembly and a packaging bag. The electrode assembly includes an electrode plate and a separator. The separator includes a porous substrate. A first coating layer is disposed on at least one surface of the porous substrate. The first coating layer includes a first polymer and a second polymer that melt at different melting points. The battery satisfies: 0.077 ≤ (3.0 - D2/D1)/T ≤ 0.118, thereby endowing the battery with superior electrochemical performance, a relatively wide hot-oven window, and a relatively high hot-oven test pass rate.",
