Abstract

A designed two-compartment cell was applied to the degradation analysis of FeF₃ having high theoretical energy density. Comparing with the result of the coin cell, the two-compartment cell gave us insight that the elution of Fe was responsible for the degradation of FeF₃ and LiDFOB was found as an essentially effective additive for suppressing the degradation of FeF₃.
