description PROBLEM TO BE SOLVED: To provide a vanadium solid-salt battery having an increased effective utilization ratio.SOLUTION: The present invention relates to a vanadium solid-salt battery comprising: electrodes containing a carbon electrode material carrying a precipitate containing vanadium or positive ions including vanadium, as an active material; and a barrier membrane partitioning between the electrodes. The precipitate covers at least a portion of the surface of the carbon electrode material. The vanadium solid-salt battery preferably includes: a negative electrode in which at least a portion of the surface of a carbon electrode material is covered by a precipitate containing vanadium of which the oxidation number changes between 2 and 3 as a result of redox reactions or positive ions including vanadium of which the oxidation number changes between 2 and 3; and a positive electrode in which at least a portion of the surface of a carbon electrode material is covered by a precipitate containing vanadium of which the oxidation number changes between 5 and 4 as a result of redox reactions or positive ions including vanadium of which the oxidation number changes between 5 and 4.
