PURPOSE: To raise the thermal stability of an electrolyte as well as to aim at improvements in the capacity of an organic electrolyte battery, by using an electrolyte which dissolves a specified Li compound and BF3 in an organic solvent.
CONSTITUTION: A halide of Li shown in a chemical formula LiX (X is of Cl, Br, I) is dissolved and dispersed in an organic solvent, and excessive BF3 is blown in this solution whereby LiX and BF3 are made into reaction. Next, the excessive BF3 is removed, adjusting an electrolyte. Using this electrolyte, an organic electrolyte batter including a button type one is assembled. This electrolyte is stable to heat and enjoys its conductivity. Therefore, an increase in internal resistance due to storage is as small as negligible as well as a drop in its discharging capacity is also little.
