The layered double metal hydroxide can be used as a battery cathode material with the advantages of good stability, easy synthesis and low price. This article mainly studies the electrochemical performance of Ruthenium-containing Fe-Ni layered double metal hydroxide as the cathode material of the battery. The experiment mainly adopts the hydrothermal method to prepare FeNiRu-LDHs, and further calcines them in an argon atmosphere at different temperatures to obtain FeNiRu-LDOs with different Ru concentrations at different temperatures. Through cyclic voltammetry curve and impedance analysis, temperature is used as a variable to determine the electrochemical performance of the material has been tested in groups, and it is found that the 20FeNi-LDO calcined at 450°C showes excellent electrochemical performance. XRD, RAMAN and SEM are further used to study the characterization properties of the sample, and it is found that the shape of Ru20FeNi-LDHs at 450°C is better. Meanwhile, the comprehensive electrochemical performance of Ru20FeNi-LDHs material is best.
