PURPOSE:To improve heat stability of lithium phosphide fluoride by using a mixture of lithium phosphide and lithium haride as an electrolyte of an organic electrolyte battery. CONSTITUTION:A compound indicated in a formula ( I ) LiRFn (R shows phosphorous, antimony, arsenic, or boron, and n is 6 when R is phosphorous, antimony, or arsenic, and is 4 when R is boron), and a compound indicated in a formula (II) LiX (X shows chlorine, bromine, or iodine) are dissolved in an organic solvent to prepare electrolyte. Examples of the compound of formula I is LiPF6, LiSbF6, LiAsF6, or LiBF4, and that of the compound of formula (II) is LiCl, LiBr, LiI. Alone or mixture of Crown ether such as 1,3-dioxolane, 4- methyl-1,3-dioxolane, 1,2-dimethoxyethane is used as a solvent. An experiment shows that a button type organic electrolyte battery using this electrolyte decreases increase of internal resistance during storage and decreases decrease of discharge capacity. |
