Modeling and synthesis of carbon-coated LiMnPO4 cathode material: Experimental investigation and optimization using response surface methodology

Nanostructured LiMnPO4 cathode materials for lithium-ion batteries (LIBs) have been successfully prepared by a modified solvothermal method under controlled conditions. Polyethylene glycol (PEG-10000) was used as solvent to optimize the particle size/mor­phology and carbon conductive matrix. In order investigate effect of synthesis parameters such concentration PEG-10000, reaction time temperature on phase purity, Response surface methodology carried out find variations in purity results across composition. The all checked using HighScore software comparing matched lines score ones reference data. As result, it has found that pure phospho-olivine material can be syn­thesized following optimum conditions: PEG = 0.1 mol l-1, 180 min, 250 °C. as-prepared opti­mum conditions delivered an initial discharge capacity 128.8 mAh g-1 at 0.05 C?rate. present work provides insights suggestions optimizing this material, which considered next promising candidate high-energy batteries.
