The synthesis of lithium ion battery cathode material by low heat solid state reaction with ionic liquid [bmim] BF_4 as template is investigated. In the experiments, ionic liquid [bmim] BF_4 is synthesized at first. Then, the lithium ion battery anode material is prepared with direction of orthogonal experiment design. Technology of data mining is introduced to get the optimal synthesis conditions. The product obtained with the optimal synthesis conditions are characterized with XRD, TG-DTA, IR and TEM, and the product is crystals of LiNi_(0.5)Mn_(0.25)Co_(0.25)O_2 in good crystallization and about 70nm in size.
