Patents by Inventor Hung Sui Lee

Hung Sui Lee has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20120183866
    Abstract: The present invention relates to electrochemical storage devices containing a non-aqueous lithium based electrolyte with high ionic conductivity, low impedance, and high thermal stability. More particularly, this invention relates to the design, synthesis and application of novel fluorinated arylboron oxalate based compounds which act as anion receptors and/or additives for non-aqueous batteries. When used as an anion receptor for non-aqueous battery electrolytes, the fluorinated arylboron oxalate enhances conductivity, lithium ion transference number and Solid Electrolyte Interface (SEI) formation capability during the formation cycling.

  • Patent number: 6352798
    Abstract: Novel fluorinated boronate-based compounds which act as anion receptors in non-aqueous battery electrolytes are provided. When added to non-aqueous battery electrolytes, the fluorinated boronate-based compounds of the invention enhance ionic conductivity and cation transference number of non-aqueous electrolytes. The fluorinated boronate-based anion receptors include different fluorinated alkyl and aryl groups.
    Type: Grant

  • Patent number: 6120941
    Abstract: A new family of aza-ether based compounds including linear, multi-branched and aza-crown ethers is provided. When added to non-aqueous battery electrolytes, the new family of aza-ether based compounds acts as neutral receptors to complex the anion moiety of the electrolyte salt thereby increasing the conductivity and the transference number of LI.sup.+ ion in alkali metal batteries.

  • Patent number: 5538812
    Abstract: The present invention relates to metal ion salts which can be used in electrolytes for producing electrochemical devices, including both primary and secondary batteries, photoelectrochemical cells and electrochromic displays. The salts have a low energy of dissociation and may be dissolved in a suitable polymer to produce a polymer solid electrolyte or in a polar aprotic liquid solvent to produce a liquid electrolyte. The anion of the salts may be covalently attached to polymer backbones to produce polymer solid electrolytes with exclusive cation conductivity.
