Abstract
A compound has a monoclinic crystal structure in which, in an X-ray diffraction chart obtained by performing measurement using CuKα ray at 25° C., a half value width of a reflection peak having the greatest peak height in a 2θ angle range of 10 to 18° is 0.05 to 0.35°, and which contains lithium, a metal element M other than lithium, chlorine and a dopant element X, in which a molar content of lithium is 20 to 40 mol %, a molar content of chlorine is 50 to 70 mol %, and an activation energy is 0.380 eV or less.

- wherein a molar content of lithium is 20 to 40 mol %,
- wherein a molar content of chlorine is 50 to 70 mol %, and
- wherein, when a solid-state 6Li-NMR spectrum is measured at room temperature under conditions in which a 6Li nucleus resonance frequency is 44.1 MHz, and no spinning occurs, a half value width of a peak present within a chemical shift range of −50 to +50 ppm is 1 to 7 ppm, based on a chemical shift of a 1 mol/L LiCl aqueous solution being 1.19 ppm.
