Abstract: Positive electrodes for secondary batteries formed with a plurality of substantially aligned flakes within a coating. The flakes can be formed from metal oxide materials and have a number average longest dimension of greater than 60 ?m. A variety of metal oxide or metal phosphate materials may be selected such as a group consisting of LiCoO2, LiMn2O4, Li(M1x1M2x2Co1-x1-x2)O2 where M1 and M2 are selected from among Li, Ni, Mn, Cr, Ti, Mg, or Al, 0?x1?0.5 and 0?x2?0.5, or alternatively, LiM1(1-x)MnxO2 where 0<x<0.8 and M1 represents one or more metal elements. Methods for making positive electrode materials are also provided involving the formation of structures with a desired longest dimension, preferably polycrystalline flakes. A cathode coating containing polycrystalline flakes may be deposited onto a conductive substrate and pressed to a desired final electrode thickness.
