Title:
FLUORIDE ION SECONDARY BATTERY NEGATIVE ELECTRODE MIXTURE COMPOSITE, FLUORIDE ION SECONDARY BATTERY NEGATIVE ELECTRODE AND SECONDARY BATTERY USING FLUORIDE ION SECONDARY BATTERY NEGATIVE ELECTRODE MIXTURE COMPOSITE, AND PRODUCTION METHOD FOR FLUORIDE ION SECONDARY BATTERY NEGATIVE ELECTRODE MIXTURE COMPOSITE
Document Type and Number:
WIPO Patent Application WO/2021/070299
Kind Code:
A1
Abstract:
Provided are: a fluoride ion secondary battery negative electrode mixture composite that makes it possible to achieve a fluoride ion secondary battery that has high initial charging/discharging efficiency and is ready to be charged; a fluoride ion secondary battery negative electrode and a secondary battery that use the composite; and a production method for the composite. The present invention uses nanoparticle-sized aluminum and a metal fluoride as negative electrode active materials to form a composite with other negative electrode mixture components and thereby suppresses the formation of an aluminum fluoride coating that is formed by a re-fluoridation reaction after de-fluoridation and also suppresses the aggregation of particles of the negative electrode active materials.
