Negative electrode active material particle, negative electrode, lithium-ion secondary battery, and production method of negative electrode active material particle |
| abstract |
A negative electrode active material particle includes natural graphite and a coating. The surface of the natural graphite is coated with the coating. The coating contains low crystalline carbon and fluorine. The low crystalline carbon has lower crystallinity than the natural graphite and a structure in which carbon hexagonal net planes are layered in a portion of the low crystalline carbon. The peak of CF2 bonds is detected by X-ray photoelectron spectroscopy of the negative electrode active material particle, and the fluorine concentration of the surface of the negative electrode active material particle is 10 atm % or more and 20 atm % or less. |
