Abstract

As conversion-type cathode materials, transition-metal chlorides are known to suffer from dissolution in organic solvents. However, our previous investigation revealed that in the Li/CuCl2 battery, the dissolution of CuCl2/C cathode materials could be suppressed by using LiPF6/methyl difluoroacetate (MFA; CHF2COOCH3) electrolyte. Consequently, its capacity decline was lessened by raising the charged voltage. Herein we examine the re-conversion reaction cathode of Cu/LiCl instead of the conversion reaction cathode of CuCl2/C. The charge-discharge characteristics of both electrodes are reported. The Cu/LiCl electrode with LiPF6/MFA could charge and discharge without carbon additives.
