Patent number: 11695156Abstract: Lithium tetrafluoro(malonato)phosphate compounds are useful as additives in lithium ion battery applications. The compounds are represented by Formula (I): MPF4[—O(C?O)—(CX?X?)—(C?O)O—]; wherein M is Li or Na; each X? and X? independently is selected from the group consisting of H, alkyl, fluoro-substituted alkyl, and F; or wherein the X? and X? together are —CR2—(CR?2)m—CR?2—; each R, R? and R? independently is selected from the group consisting of H methyl, trifluoromethyl, and F; and in is 0 or 1. These compounds can be prepared in high purity and a high yield by reaction of a metal hexafluorophosphate with a bis-silyl malonate compound. A similar oxalato compound, lithium tetrafluoro(oxalato)phosphate), can be made in the same manner, but using a bis-silyl oxalate in place of the bis-silyl malonate. Advantageously, the compounds can be formed, in situ, in a LiPF6-containing electrolyte solution.Type: GrantFiled: October 19, 2020Date of Patent: July 4, 2023Assignee: UCHICAGO ARGONNE, LLCInventors: Chen Liao, Ilya A.

Patent number: 8722415Abstract: This invention provides methods of using modified magnetic microspheres to extract target ions from a sample in order to detect their presence in a microfluidic environment. In one or more embodiments, the microspheres are modified with molecules on the surface that allow the target ions in the sample to form complexes with specific ligand molecules on the microsphere surface. In one or more embodiments, the microspheres are modified with molecules that sequester the target ions from the sample, but specific ligand molecules in solution subsequently re-extract the target ions from the microspheres into the solution, where the complexes form independent of the microsphere surface. Once the complexes form, they are exposed to an excitation wavelength light source suitable for exciting the target ion to emit a luminescent signal pattern. Detection of the luminescent signal pattern allows for determination of the presence of the target ions in the sample.Type: GrantFiled: March 2, 2011Date of Patent: May 13, 2014Assignee: U.S. Department of EnergyInventors: Ilya A.
