  "textContent": "The present application provides an electrolyte solution, a secondary battery and a power consuming device. The electrolyte solution contains a solvent, an additive and a lithium salt. The solvent includes a first solvent and a second solvent, the first solvent being a cyclic ester solvent, and the second solvent being a linear carboxylic ester solvent. The additive includes a film forming additive. Based on the total mass of the electrolyte solution, the lithium salt has a mass fraction of W1, the film forming additive has a mass fraction of W2, and the second solvent has a mass fraction of W3, which satisfy the following relationship: 0.2 ≤ (W1 + W2)/W3 ≤ 0.4. The present application can achieve both good dynamic performance and good high-temperature cycling performance of the battery, and enable a negative electrode to be fully protected.",
