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

The CuMn 2 O 4 anode materials were synthesized using a chemical coprecipitation method with different precipitants, specifically (NH 4 ) 2 C 2 O 4 and NH 4 HCO 3 . The impact of these precipitants on the structure, morphology, and electrochemical properties of CuMn 2 O 4 was investigated. Comparati...

Description
Summary:The CuMn 2 O 4 anode materials were synthesized using a chemical coprecipitation method with different precipitants, specifically (NH 4 ) 2 C 2 O 4 and NH 4 HCO 3 . The impact of these precipitants on the structure, morphology, and electrochemical properties of CuMn 2 O 4 was investigated. Comparative analysis revealed that CuMn 2 O 4 samples prepared with NH 4 HCO 3 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.
