Title: Synthesis and characterization of LiNiO{sub 2} as a cathode material for pulse power batteries

Abstract

The optimum conditions for preparing LiNiO{sub 2} with good electrochemical performance are presented. Three different methods were investigated: LiOH and NiO at 700 C in air (Batch A), LiOH and NiO between 150 and 750 C in oxygen (Batch B), and LiNO{sub 3} and NiCO{sub 3} between 600 and 750 C in oxygen (Batch C). Batch C exhibited the highest first discharge capacity of about 150 mAh/g between 2.0 and 4.0V with a solid state Li/LiNiO{sub 2} cell containing a PAN-based polymer electrolyte. Solid state carbon/LiNiO{sub 2} cells and two-cell bipolar batteries demonstrated high rate capabilities at room temperature with an ability to sustain pulsed discharge currents as high as 50 mA/cm{sup 2}. About 22,500, 13,000, and 1,000 pulses were obtained at current densities of 10, 20, and 50 mA/cm{sup 2}, respectively, with a 10 ms pulse width followed by a 50 ms interpulse rest period.
