Claim:
1. A method of preparing lithium transition metal phosphate, the method comprising: feeding reactants comprising an acidic source material and a basic source material into a reactor, and mixing the reactants at a molecular level in the reactor; generating a crystal nucleus by chemically reacting the reactants in the reactor, wherein a time (T growing the crystal nucleus into a nano-sized crystal to obtain a slurry comprising a lithium transition metal phosphate; and then filtering, washing, drying and/or heating the slurry to prepare a nanoparticle lithium transition metal phosphate, wherein the acidic source material is fed into the reactor through a first source material feeding line and the basic source material is fed into the reactor through a second source material feeding line, wherein the acidic source material comprises lithium, a transition metal, and phosphoric acid, and the basic source material comprises an inorganic base; the acidic source material comprises a transition metal and phosphoric acid, and the basic source material comprises lithium; the acidic source material comprises lithium and phosphoric acid, and the basic source material comprises a transition metal; or the basic source material comprises lithium and a transition metal, and the acidic source material comprises phosphoric acid, wherein the reactor is a high gravity rotating packed bed reactor including:
