Influence of different precipitants on the properties of CuMn2O4 anode materials for Lithium-ion batteries

Abstract

The CuMn₂O₄ anode materials were synthesized using a chemical coprecipitation method with different precipitants, specifically (NH₄)₂C₂O₄ and NH₄HCO₃. The impact of these precipitants on the structure, morphology, and electrochemical properties of CuMn₂O₄ was investigated. Comparative analysis revealed that CuMn₂O₄ samples prepared with NH₄HCO₃ exhibited a spherical structure, the smallest particle size, and superior electrochemical performance. Notably, at a current density of 100 mA·g⁻¹, the discharge specific capacity reached 1104.2 mAh·g⁻¹, with a capacity retention of 204.7 mAh·g⁻¹ after 200 cycles.
