Non-aqueous electrolytes of electrochemical cells, rechargeable, high energy and electrochemical cell

摘要

"NON-AQUEOUS ELECTROLOGY OF ELECTROCHEMICAL CELLS, RECHARGEABLE, HIGH ENERGY AND ELECTROCHEMICAL CELL". The present invention provides a non-aqueous electrolyte for use in an electrochemical cell comprising: (a) at least one organic solvent; (b) at least one electrolytically active salt represented by the formula: M ^ '+ m ^ (ZR ~ n ~ X ~ qn ~), in which M' is selected from a group consisting of magnesium, calcium, aluminum, lithium and sodium ; Z is selected from a group consisting of aluminum, boron, phosphorus, antimony and arsenic; R represents radical selected from the following groups: alkyl, alkenyl, aryl, phenyl, benzyl, and starch; X is a halogen (i, Br, C1, F); m = 1-3; and n = 0-5 and q = 6 in the case of Z = phosphorus, antimony and arsenic, and n = 0-3 and q = 4 in the case of Z = aluminum and boron. High-energy, rechargeable electrochemical cells containing an intercalating cathode, a metal anode, and an electrolyte of the type described above are also disclosed.
