(GB2124821-A)      Cell has an active metal anode (a): a liq. electrolyte (b); and an active, solid cathode (c).    Liq. (b) is a solvate complex with low vapour pressure, contg. SO2, plus one or more alkali(ne earth) metal salts (b1) soluble in SO2 and forming a complex. The equiv. ratio (ER) of b1:SO2 is between 1:1 and 1:7.    Anode (a) is pref. Li.    Salt (b1) is pref. LiAlCl4, LiGaCl4, LiBF4, LiBCl4, LiInCl4, NaAlCl4, NaGaCl4, NaBF4, NaBCl4, NaInCl4, Ca(AlCl4)2, Ca(GaCl4)2, Ca(BF4)2, Ca(BCl4)2, Ca(InCl4)2, Sr(AlCl4)2, Sr(GaCl4)2, Sr(BF4)2, Sr(BCl4)2, Sr(InCl4)2, Li3SbCl6, and/or LiSbCl4.    Numerous pref. cathodes (c) include poly-p-phenylene or its sulphide, but the esp. pref. materials (c) are CuCl2, CuO, CuS or MnO2.    (8pp)    (US4891281-A)      Non-aq., electrochemical cell has an active metal anode; a solid active cathode; and a liq. electrolyte. The improvement is that the electrolyte comprises a low vapour pressure, liq. solvate-complex of (a) sulphur dioxide and (b) one or more alkali or alkaline earth metal salts which are soluble in sulphur dioxide and can form a complex with it.    The salts comprise a stoichiometric reaction prod. of a Lewis acid and a Lewis base, with the equiv. ratio of the salts to SO2 in the liq. electrolyte ranging from 1:1 to 1:7. All of the salts is complexed with the SO2. Pref. the salts contain Gp. 3A element halide anions.    USE/ADVANTAGE -   A low vapour pressure electrolyte is provided based on SO2, which is, e.g., safer than conventional organic electrolytes.    (8pp)    (DE3328609-C)      A non-aq. electrochemical cell includes an active metal anode, an active cathode and a liq. electrolyte. The electrolyte contains a liq. sulphur dioxide complex, which has a low vapour pressure and which consists of a sulphur dioxide component and one or more alkali- or alkali earth metals. The equivalent ratio of one or more salts to SO2 in the liq. electrolyte is in the region 1:1 to 1:7.    ADVANTAGE -   The cell is efficient and reliable and is only held under low pressure.    (9pp)    (JP92035876-B)      The battery has an active metal anode (a); a liq. electrolyte (b); and an active, solid cathode (c). Liq. (b) is a solvate complex with low vapour pressure, contg. SO2, plus one or more alkali(ne earth) metal salts (b1) soluble in SO2 and forming a complex. The equiv. ratio (ER) of b1:SO2 is between 1:1 and 1:7. Anode (a) is pref. Li.    Salt (b1) is pref. LiAlCl4, LiGaCl4, LiBF4, LiBCl4, LiInCl4, NaAlCl4, NaGaCl4, NaBF4, NaBCl4, NaInCl4, Ca(AlCl4)2, Ca(GaCl4)2, Ca(BF4)2, Ca(BCl)2, Ca(InCl4)2, Sr(AlCl4)2, Sr(GaCL4)2, Sr(BF4)2, Sr(BCL4)2, Sr(InCl4)2, Li3SbCl6, and/or LiSbCl4. Numerous pref. cathodes (c) include poly-p-phenylene or its sulphide, but the esp. pref. materials (c) are CuCl2, CuO, CuS or MnO2. (J59049159-A)
