Composite electrodes (similar to 9 pm in thickness) composed of 5V-class electrode of LiNi(0.5)Mr(1.5)O(4) (LNM) and high Li+ conductive crystalline-glass solid electrolyte (LATP, Ohara Inc.) were prepared at room temperature by aerosol deposition (AD) on platinum sheets. The resultant LNM-LATP composite electrodes were combined with LiPON and Li, and 5V-class bulk-type all-solid-state rechargeable lithium batteries (SSBs) were prepared. The crystallnity of the LNM in the LNM-LATP composite electrode was improved by annealing. Both thermo-gravimetry-mass spectroscopy analysis and XRD analysis clarified that the side reactions between the LNM and the LATP occurred over 500 degrees C with oxygen release. From these results, annealing temperature of the LNM-LATP composite electrode system was optimized at 500 degrees C due to the improved crystallinity of the LNM with avoiding the side-reactions. The SSBs with the composite electrodes (9 pm in thickness, 40 vol% of the LNM) annealed at 500 degrees C delivered 100 mAh g(-1) at 10 mu A cm(-2) at 100 degrees C. Degradation of the discharge capacity with the repetition of the charge-discharge reactions was observed, which will originate from large volume change of the LNM (similar to 6.5%) during the reactions.
