Notes:
Amorphous fine powder in the Li2O-Al2O3-TiO2-P2O5 (LATP) system were prepared directly from amixture of Li2O, Al2O3, TiO2, and P2O5 as starting materials using a mechanical milling technique atroom temperature. LATP glass-ceramics were obtained by heat treatment of the mechanochemicallyprepared amorphous powder over the crystallization temperature. X-ray diffraction peaks due toLiTi2(PO4)3 and AlPO4 crystals for LATP glass-ceramics were observed. Thus, high lithium ionconducting LATP glass-ceramics solid electrolytes were prepared successfully from themechanochemically prepared amorphous powder. The LATP glass-ceramic fine particles wereinvestigated as coating materials of LiCoO2 cathode in lithium ion batteries. The LATPglass-ceramics coated LiCoO2 electrode materials exhibited a good charge-discharge performance forcharging up to a high voltage (4.5 V vs. Li/Li+)
