Title: Chromium (V) compounds as cathode material in electrochemical power sources

Abstract

A cathode for use in a thermal battery, comprising a chromium (V) compound. The preferred materials for this use are Ca/sub 5/(CrO/sub 4/)/sub 3/Cl, Ca/sub 5/(CrO/sub 4/)OH, and Cr/sub 2/O/sub 5/. The chromium (V) compound can be employed as a cathode material in ambient temperature batteries when blended with a suitably conductive filler, preferably carbon black.

  • A cathode for use in a thermal battery, comprising a chromium (V) compound. The preferred materials for this use are Ca.sub.5 (CrO.sub.4).sub.3 Cl, Ca.sub.5 (CrO.sub.4).sub.3 OH, and Cr.sub.2 O.sub.5. The chromium (V) compound can be employed as a cathode material in ambient temperature batteries when blended with a suitably conductive filler, preferably carbon black.
  • A cathode for use in a thermal battery, comprising a chromium (V) compound. The preferred materials for this use are Ca/sub 5/(CrO/sub 4/)/sub 3/Cp, Ca/sub 5/(CrO/sub 4/)/sub 3/OH, and Cr/sub 2/O/sub 5/. The chromium (V) compound can be employed as a cathode material in ambient temperature batteries when blended with a suitably conductive filler, preferably carbon black.
  • A cathode for use in a lithium electrochemical cell is described comprising a mix of about 40 to 99 weight percent of a mixed metal oxide prepared from V/sub 2/O/sub 5/ and MoO/sub 3/, wherein the mixed metal oxide prepared from V/sub 2/O/sub 5/ and MoO/sub 3/ is selected from the group consisting of V/sub 9/Mo/sub 6/O/sub 40/, a solid solution of V/sub 9/Mo/sub 6/O/sub 40/ with V/sub 2/O/sub 5/, and a solid solution of V/sub 9/Mo/sub 6/O/sub 40/ with MoO/sub 3/, about 0 to 30 weight percent of a conductive diluent and about 1 to 30 weight percent ofmore » an aqueous based binder, wherein the mix is rolled onto a nickel screen and sintered under vacuum at about 280/sup 0/C.« less
  • A cathode for use in a lithium electrochemical cell is described comprising a cathode mix of amorphous materials prepared from the mixed-metal oxide (V/sub 0.7/Mo/sub 0.3/)/sub 2/O/sub 5/ and P/sub 2/O/sub 5/ combined with a mixture of conductive diluent and binder and pressed into electrodes on a nickel screen and sintered under vacuum at about 280/sup 0/C.
  • The invention described herein may be manufactured, used, and licensed by or for the Government for governmental purposes without the payment to us of any royalty thereon. This invention relates in general to a cathode for use in a lithium electrochemical cell and in particular to such a cathode including a cathode mix of amorphous materials from the mixed - metal oxide (V0.7Mo0.3)205 and P/sub 2/O/sub 5/ as the cathode active material. The general object of this invention it to provide an improved cathode for use in a lithium electrochemical cell. A more specific object of the invention is tomore » provide an inexpensive high-energy material with excellent cycle life and rate capabilities for use as the cathode of a lithium electrochemical cell. Another object is to provide a cathode for use in a lithium electrochemical cell that will be capable of discharging the cell to even lower voltages than were obtained with the cathode of S.N. 059,346.« less
