Abstract: A battery electrolyte solution contains from 0.001 to 20% by weight of certain phosphorus-sulfur compounds. The phosphorus-sulfur compound performs effectively as a solid-electrolyte interphase (SEI) forming material. The phosphorus-sulfur compound has little adverse impact on the electrical properties of the battery, and in some cases actually improves battery performance. Batteries containing the electrolyte solution form robust and stable SEIs even when charged at high rates during initial formation cycles.

Abstract: Hybrid polyester-polyether polyols are prepared by polymerizing an alkylene oxide in the presence of a carboxylate initiator. The polymerization is catalyzed with a mixture of double metal cyanide catalyst complex and certain magnesium, group 3-group 15 metal or lanthanide series metal compounds. The presence of the magnesium, Group 3-Group 15 metal or lanthanide series metal (MG3-15LA) compound makes for consistently rapid activation of the double metal cyanide catalyst complex, even in the presence of carboxylate initiator compounds. This leads to greater productivity and reduced manufacturing costs due to shorter cycle times and less waste of raw materials due to the failure of the catalyst to become activated. Once the catalyst is activated, it often polymerizes the alkylene oxide at a faster rate that the DMC catalyst by itself.
