Abstract
A preparation method of a composite Prussian blue sodium ion battery positive electrode material belongs to the field of new energy batteries, and specifically comprises the following steps: 1, adding manganese-based Prussian blue into deionized water, and uniformly stirring to obtain a suspension; 2, dropwise adding a transition metal ion salt solution into the turbid liquid, stirring for a period of time, dropwise adding a sodium ferrocyanide solution into a reaction system, stirring for precipitation reaction, aging a reaction product, and centrifugally washing and drying to obtain the composite Prussian blue sodium ion battery positive electrode material; the transition metal element comprises one or a combination of more of Ni, Cu, Co, Zn and Fe. The compounding can inhibit the volume deformation of the manganese-based Prussian blue material in the long-cycle process, and the cycle performance is effectively improved.
