摘要
FIELD: power engineering.;SUBSTANCE: invention relates to electrochemical power engineering, namely to compositions of anhydrous aprotic electrolytes intended for use in chemical power sources with negative electrodes based on intercalation compounds of sodium and titanium with Nasicon structure. According to the invention, as electrolytes in sodium-ion accumulators one proposes to use solutions of difluoro(oxalato)sodium borate in a solvent glutaronitrile, using two additional solvents – ethyl acetate and diethyl carbonate.;EFFECT: reduced lower temperature limit for storage of sodium-ion accumulators and sodium-ion electrolyte.;6 cl, 3 dwg, 2 tbl, 4 ex
