It is known that LiPF_6 reacts with water. In this study LiC1, LiF, LiBr and LiI were added to the LiPF_6 electrolyte with about 5000ppm water to inhibit the decomposition of LiPF_6. When 0.1M LiC1 was added, the LiPF_6 electrolyte with water did not decompose for 50 hours. From DSC measurement, it was found that the amount of an exothermic heat at 265℃ did not change at all for 48 hours when LiC1 was added. It suggests that LiPF_6 salt was not decomposed.
