Title:
NEGATIVE ELECTRODE ACTIVE MATERIAL FOR FLUORIDE ION SECONDARY BATTERIES, NEGATIVE ELECTRODE USING SAID ACTIVE MATERIAL, FLUORIDE ION SECONDARY BATTERY, AND METHOD FOR PRODUCING SAID ACTIVE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2019/187943
Kind Code:
A1
Abstract:
Provided are: a negative electrode active material for fluoride ion secondary batteries, which is capable of causing a reversible negative electrode reaction with a high utilization rate in a fluoride ion secondary battery; a negative electrode which uses this active material; a fluoride ion secondary battery; and a method for producing this active material. This negative electrode active material for fluoride ion secondary batteries is composed of a modified aluminum fluoride (AlF3) which is obtained by partially deintercalating a fluoride ion (F-) from aluminum fluoride (AlF3) in advance, thereby modifying such that a vacancy is present in a position where a fluorine atom used to be present.
