(57) [Summary] Lithium metal oxide particles having an average particle size of about 100 nm or less were prepared. Particularly interesting composite oxides include, for example, lithium cobalt oxide, lithium nickel oxide, lithium titanium oxide and derivatives thereof. The composite oxide of these nanoparticles can be used for electrically active particles in a lithium secondary battery or a lithium ion secondary battery. Particularly interesting secondary batteries include those using lithium titanium oxide for the negative electrode and lithium cobalt manganese oxide for the positive electrode. |
