  "textContent": "This secondary battery comprises a positive electrode, a negative electrode, and an electrolyte solution. The electrolyte solution includes a solvent containing water as a main component, and a lithium salt. The negative electrode has a negative electrode active material that includes a carbon material. The Raman spectrum of the carbon material, which is obtained by Raman spectroscopy, indicates that the peak intensity ratio between the D-band and the G-band (D/G) is 0.3 or greater. This secondary battery can suppress the reductive decomposition of the water-based electrolyte solution.",
