  • Patent number: 8574773
    Abstract: A battery electrolyte solution contains from 0.01 to 80% by weight of an aromatic phosphorus compound. The aromatic phosphorus compound provides increased thermal stability for the electrolyte, helping to reduce thermal degradation, thermal runaway reactions and the possibility of burning. The aromatic phosphorus compound has little adverse impact on the electrical properties of the battery, and in some cases actually improves battery performance.

  • Patent number: 4808282
    Abstract: Included is an invention, which in one aspect, is a process for preparing a product of an alkaline earth metal compound having at least one BVB-heteromoeity and by-product of an alkali metal substance comprising operating an electrochemical cell, said cell having(1) a sacrificial alkaline earth metal anode,(2) a liquid electrolyte, which contains a solvent that is generally inert and a solute that has at least a residual alkali metal moiety and an incorporatable BVB-heteromoiety therein, and(3) an alkali metal substance segregative cathode, under conditions whereby said product and by-product are prepared. Provided, among other products, are alkaline earth metal organoborates. For example, magnesium triethylpyrrolylborate can be prepared by employing a magnesium anode, a solution of lithium triethylpyrrolylborate in tetrahydrofuran and a cupric oxide and carbon containing cathode.
