Polyradical compound-conductive material composite, method for producing the same, and battery using the same

摘要

An exemplary embodiment provides: a composite of an electrode active material and an electric conductivity-imparting agent, which has a high capacity density and can produce a large current; a method for producing it; and a battery which has a high energy density and can produce a large output. Specifically, a polyradical compound as the electrode active material and a conductive material are heated and mixed at a temperature of not less than the softening temperature of the polyradical compound and less than the decomposition temperature thereof to form a composite of the polyradical compound and the conductive material. Fabricating an electrode using the composite can provide a novel battery having a high energy density and a large output.
