Influence of different precipitants on the properties of CuMn2O4 anode materials for Lithium-ion batteries
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.
期刊介绍：
Ionics is publishing original results in the fields of science and technology of ionic motion. This includes theoretical, experimental and practical work on electrolytes, electrode, ionic/electronic interfaces, ionic transport aspects of corrosion, galvanic cells, e.g. for thermodynamic and kinetic studies, batteries, fuel cells, sensors and electrochromics. Fast solid ionic conductors are presently providing new opportunities in view of several advantages, in addition to conventional liquid electrolytes.
