The invention provides a nano anhydrous iron phosphate and a synthesis method thereof. Compared with the prior art, the method solves the problem of pollution caused by using the traditional method, and provides a new method and a new idea for the synthesis of iron phosphate. The synthesis method for self-generating electricity uses cheap iron as the raw material for preparing iron phosphate material, the costs are reduced, a single phosphate aqueous solution is used as the electrolyte, external ion is not introduced, the process is simplified, and the obtained product is high in purity, and easy for mass production. The synthesis method for self-generating electricity is adopted, the prepared nano-phosphate anhydrous iron is high in purity, the prepared lithium iron phosphate is used in the anodic lithium-ion batteries and can improve the performance of the charging and discharging of the batteries, which increases the charging and discharging capacity of the lithium-ion batteries. 本发明提供了种纳米无水磷酸铁及其合成方法，与现有技术
