<P>PROBLEM TO BE SOLVED: To provide an electrode material obtained by using a sulfide-based solid electrolyte which is low in manufacturing cost and small in hydrogen sulfide generation amount and a positive electrode active material which has high theoretical capacity. <P>SOLUTION: An electrode material includes: at least one of sulfur and a compound including sulfur atoms; a conductive substance; and a solid electrolyte including lithium atoms, phosphorus atoms and sulfur atoms. The solid electrolyte has a peak at least one of at 86.1±0.6 ppm and 83.0±1.0 ppm in a solid<SP POS="POST">31</SP>PNMR spectrum, and the ratio of phosphorus atoms contained in the peak is 62 mol% or more relative to phosphorus atoms contained in all of the peaks. <P>COPYRIGHT: (C)2013,JPO&INPIT |
