Abstract
A powder of lithiated manganese oxide has an average particle diameter preferably less than about 250 nm. The particles have a high degree of uniformity and preferably a very narrow particle size distribution. The lithiated manganese oxide can be produce by the reaction of an aerosol where the aerosol comprises both a first metal (lithium) precursor and a second metal (manganese) precursor. Preferably, the reaction involves laser pyrolysis where the reaction is driven by heat absorbed from an intense laser beam.
