Abstract

The present invention provides: a negative electrode mixture composite body for fluoride ion secondary batteries, said composite body enabling the achievement of a fluoride ion secondary battery that has high initial charge/discharge efficiency; a negative electrode for fluoride ion secondary batteries and a secondary battery, each using this composite body; and a method for producing this composite body. According to the present invention, a composite body is formed using, as a negative electrode active material, nanometer-sized aluminum particles together with the other constituents of a negative electrode mixture, so that coating by aluminum fluoride that is formed by a re-fluoridation reaction after defluoridation is suppressed, while suppressing aggregation of negative electrode active material particles.
