Abstract
Provided is a negative electrode active material that is applied in an aqueous secondary battery in which is used an aqueous electrolyte containing water and a lithium salt. The negative electrode active material contains hardly-graphitizable carbon, and the hardly-graphitizable carbon has a C—F bond group on the surface thereof. In an XPS spectrum obtained through X-ray photoelectron spectroscopy, when the peak intensity near 688 eV originating from C—F bonds of the hardly-graphitizable carbon is denoted by I688eV, the peak intensity near 284 eV originating from C—C bonds is denoted by I284eV, a ratio of the peak intensity I688eV to the peak intensity I284eV (value of I688eV/I284eV) is denoted by X, and the BET specific surface area (m2/g) is denoted by Y, the X and Y satisfy Y<(−0.3X+3.75), 0.1≤X≤5, and Y≥2.
