David M. Pasquariello 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).

  • Systems and methods for catalyst reactivation
    Patent number: 6419880
    Abstract: The invention includes systems and methods which allow reactivation of supported noble metal catalysts. The method involves heating the catalyst in the presence of a gaseous hydrocarbon in the absence of oxidizing agents. Systems of the invention provide for in situ reactivation of catalytic material.
    Type: Grant

  • Chemical overcharge protection of lithium and lithium-ion secondary batteries
    Patent number: 5858573
    Abstract: This invention features the use of redox reagents, dissolved in non-aqueous electrolytes, to provide overcharge protection for cells having lithium metal or lithium-ion negative electrodes (anodes). In particular, the invention features the use of a class of compounds consisting of thianthrene and its derivatives as redox shuttle reagents to provide overcharge protection. Specific examples of this invention are thianthrene and 2,7-diacetyl thianthrene. One example of a rechargeable battery in which 2,7-diacetyl thianthrene is used has carbon negative electrode (anode) and spinet LiMn.sub.2 O.sub.4 positive electrode (cathode).

  • Solid polymer electrolytes to alleviate voltage delay of lithiium cells
    Patent number: 5332631
    Abstract: An electrochemical cell, comprising a lithium anode, a cathode, and a liquid electrolyte of lithium tetrachloroaluminate dissolved in thionyl chloride, has a coating of a Li ion conductive solid polymer electrolyte on the anode. An example of the solid polymer electrolyte is a Li salt complex of poly[bis(methoxyethoxyethoxy)phosphazene].

  • Cathode-active materials for secondary batteries
    Patent number: 4934922
    Abstract: A secondary, rechargeable, battery comprising as a cathode-active material, a transition metal oxysulfide having the formula:M.sub.y.sup.1 M.sub.l.sup.2.sub.--Y O.sub.x S.sub.n--xwhereinM.sup.1 and M.sup.2 are transition metals, y is higher than zero but not higher than 1, x is higher than zero and less than 1, and n is half the sum of the oxidation states of the transition metals M.sup.1 and M.sup.2, preferably molybdenum oxysulfide; an anode active material; and an electrolyte. Also disclosed is a method of making such a transition metal oxysulfide by mixing at least one transition metal oxide and at least one transition metal sulfide in aqueous ammonia, removing the ammonia and then decomposing the residue at elevated temperature under non-oxidizing conditions.

  • Overcharge protection of secondary, non-aqueous batteries
    Patent number: 4857423
    Abstract: The invention features the use of redox reagents, dissolved in non-aqueous electrolytes, to provide overcharge protection for cells having alkali metal negative electrodes (anodes). In particular, the invention features the use of organometallic compounds, known as metallocenes, as redox shuttle reagents to provide overcharge protection. Specific examples of this invention are bis(cyclopentadienyl)iron, known as ferrocene; bis(n-butyl-cyclopentadienyl)iron, known as butylferrocene; bis(cyclopentadienyl)nickel, known as nickelocene; and bis(cyclopentadienyl)cobalt, known as cobaltocene. An example of a rechargeable battery in which these redox reagents are used as an Li negative electrode and a TiS.sub.2 positive electrode.
