Lithium-ion batteries

Improved lithium-ion batteries in which the cathode comprises particles that include (i) transition metal grains having a grain size no greater than about 50 nanometers; and (ii) lithium-containing grains selected from the group consisting of lithium oxides, lithium sulfides, lithium halides (e.g., chloride, bromides, iodides, or fluorides), and combinations thereof.
