摘要: Abstract Elaboration of materials with nanodomain structures is a new approach for improving the electrochemical properties electrodes lithium ion batteries. In this study, effects structure and particle size distribution on intercalation Li+ in Li4Mn5O12 are examined by applying powder X-ray diffractions, TEM electron paramagnetic resonance spectroscopy (EPR). The composite XRD-pure comprises layered- spinel-like nanodomains. formation structure, as well distribution, effectively controlled two methods synthesis: oxalate acetate precursor techniques. into spinel compositions analysed model cells galvanostatic mode. surface interaction electrolyte solution followed photoelectron (XPS). results obtained reveal that capacity 3 V-range determined extent non-homogeneous Mn4+, while cycling stability result from morphology. between electrode bears impact sizes.
