Abstract
In one aspect of the invention, a method of synthesizing a lithium metal phosphate composite usable for a lithium secondary battery includes the steps of forming a nanometer-size precursor comprising lithium source and metal phosphate nanoparticles having each nanoparticle at least partially coated a layer of carbon precursor, spray drying the nanometer-size precursor at a first desired temperature to form micron-size particles packed with the lithium metal phosphate precursor nanoparticles, and sintering the micron-size particles at a second desired temperature under an inert and/or reduction atmosphere to form a micron-size lithium metal phosphate composite.
