    The invention relates to chemical current sources and relates to an oxide of an electrolyte for a current source with an active anode and an indifferent cathode. An oxidizing electrolyte of a chemical current source is known, containing an active anode, an indifferent cathode, liquid halide, or liquid non-metallic halide, or liquid nonmetallic oxide as a solvent, and anion and cation of the metal, which form an electrolyte salt. current at elevated temperature anvd is passivated due to the formation of electrically insulating film on it. For this, in the proposed electrolyte, an anion of a clover borate of the general formula (B, X,) is taken as the anion. M 6-20; n 6-1c, K 1-4; in - boron; X is hydrogen, fluorine, chlorine, bromine, iodine, hydroxyl, or a combination thereof. As an anion, it can be a BIO, as a solvent is thionyl chloride, sulfur dioxide. Such an electrolyte helps to reduce the passivation of the metal anode, which makes it possible to reduce the holding time of the element when it is switched on after storage at elevated temperatures. The preferred concentration of the electrolyte salt, e.g., CPio, is 10-25% by weight of the electrolyte, the conductivity of pure and thionyl is 3.5 x 10 ohm cm. Based on this, the ratio between thionyl chloride and electrolyte salt should be chosen so that the electrolyte conductivity at 2-0 C lies in the range from 4.0 X S to 1.0 X. The table compares the recovery time of the known current source and the previous one. that were stored for 4 days at (discharge current 0.5 A). The Known Replaced Does Not Work. As can be seen from the data in the table, a current source restores the voltage more quickly than is known. as a solvent and. a metal cation and an anion forming an electrolyte salt, which is due to the fact that, in order to reduce the anode passivation, the cloven boil anion of the General formula is taken as the anion. .
