  "textContent": "A 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−D/D)/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.",
