摘要:
Orthoborate salts suitable for use as electrolytes in lithium batteries and methods for making the electrolyte salts are provided. The electrolytic salts have one of the formulae (I). In this formula anionic orthoborate groups are capped with two bidentate chelating groups, Y1 and Y2. Certain preferred chelating groups are dibasic acid residues, most preferably oxalyl, malonyl and succinyl, disulfonic acid residues, sulfoacetic acid residues and halo-substituted alkylenes. The salts are soluble in non-aqueous solvents and polymeric gels and are useful components of lithium batteries in electrochemical devices.
摘要:
A method for the removal, separation, and concentration of alkali metal, alkaline earth metal, Pb and/or Tl cations from a source solution which may contain larger concentrations of other ions which comprises bringing the source solution into contact with a compound comprising an oxygen donor macrocycle-containing ligand covalently bonded through an organic spacer silicon grouping to a solid inorganic support.
