Abstract

The optimum conditions for preparing LiNiO2 with good electrochemical performance are presented. Three different methods were investigated:

• LiOH and NiO at700°C in air(Batch A),

• LiOH and NiO between 150 and 750 °C in oxygen (Batch B), and

• LiNO3 and NiCO3 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/LiNiO2 cell containing a PAN-based polymer electrolyte. Solid state carbon/LiNiO2 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/cm2. About 22 500,13 000, and 1000 pulses were obtained at current densities of 10, 20, and 50 mA/cm2, respectively, with a 10 ms pulse width followed by a 50 ms interpulse rest period.
