摘要: Abstract A low-temperature, hydrothermal process for the synthesis of high-quality intercalation oxide LiMnO 2 has been developed. Mn 3 O 4 as a precursor was prepared by oxidation Mn(OH) bubbling at 80 °C. The fine single crystalline particle oxide, , hydrothermally treated with various LiOH concentrations 170 mechanism phase evolution studied using X-ray diffraction (XRD) and transmission electron microscopy (TEM). Rietveld analysis revealed that well-ordered orthorhombic having zigzag layer structure ( Pmnm ) readily formed reaction. product is electrochemically active shows relatively high capacity upon cycling.
