NOVELTY - Positive electrode material comprises lithium metal halide compound (I) and carbon material capable of occluding elemental halogen and/or halide. USE - The positive electrode material is useful in all-solid-state battery (claimed), preferably lithium ion battery. ADVANTAGE - The positive electrode material improves the output and current density of battery, exhibits high ionic conductivity, realizes excellent charge/discharge characteristics of battery, ensures excellent reduction stability, and improves the average discharge voltage of battery. DETAILED DESCRIPTION - Positive electrode material comprises lithium metal halide compound of formula: LiaMbXc (I) and carbon material capable of occluding elemental halogen and/or halide. a, b, c = more than 0; M = metal elements other than Li and semi-metal elements;and X = halo. INDEPENDENT CLAIMS are included for the following: (1) a battery comprising a positive electrode comprising the positive electrode material, a negative electrode and an electrolyte layer arranged between the positive electrode and negative electrode; and (2) a negative electrode comprising a negative electrode active material capable of absorbing lithium.
