  • Research on the deposition and characterization of amorphous lithium electrolyte and vanadium oxide thin films was undertaken with the goal of developing a thin-film rechargeable lithium battery. Most of this effort has focused on the electrolyte film, with less but increasing attention given to the cathode. Recent studies on these films and rechargeable thin-film lithium cells will be reviewed in this paper.

  • The electrochemical stability and capacitance in H{sub 2}SO{sub 4}, KOH, and propylene carbonate of single phase polycrystalline {gamma}-Mo{sub 2}N and {delta}-MoN thin film electrodes deposited at 350 and 700 C, respectively, at a rate of 0.5 {micro}m/min on Ti substrates have been determined. The films were prepared by chemical vapor deposition at 100 torr using Mo(CO){sub 6} and NH{sub 3} flowing at 1.5 standard liters per minute (slm). Cyclic voltammetry referenced to a standard Ag/AgCl electrode indicated that both phases possessed a more positive voltage stability limit in H{sub 2}SO{sub 4} than KOH. Films of {gamma}-Mo{sub 2}N had voltage stabilitymore » ranges of {minus}0.3 to 0.6 V and {minus}1.3 to {minus}0.3 V in 4.4 M H{sub 2}SO{sub 4} and 7.6 M KOH, respectively. Films of {delta}-MoN possessed voltage stability ranges of {minus}0.3 to 0.7 V and {minus}1.3 to {minus}0.3 V in the same respective electrolytes. Both phases had a voltage stability of approximately one volt in the propylene carbonate electrolyte. These results were used to design and fabricate a hybrid capacitor composed of a Ta/Ta{sub 2}O{sub 5} anode and a {delta}-MoN cathode contained in an electrolyte of 4.4 M H{sub 2}SO{sub 4}. The hybrid device had an operating voltage range between 0 and 50 V, a temperature range of {minus}55 to +90 C, a capacitance of {approx}5.0 mF and an energy density of {approx}1.32 J/cm{sup 3}. This device is now in pre-production at Evans Capacitor Corporation.« less
