Resumo

The paper presents a new low-temperature method for the synthesis of highly dispersed powders of double phosphates LiCoPO₄ and LiNiPO₄ using low-waste technology. It has been shown that the morphology and particle size of the obtained materials depend on the type of initial precursors. The obtained compounds are characterized by elemental, XRD, SEM, cyclic volammetry, cyclic chronopotentiometry analyses. A new approach to the synthesis of submicron powders of lithium double phosphates and transition metal (nickel, cobalt) is more effective compared to current methods.
