Abstract
Mesoporous orthorhombic LiMnO2 has been directly fabricated by a one-step flux method in this work. Benefiting from the unique mesoporous structure, the orthorhombic LiMnO2 prepared through calcinating the mixture of flux LiOHH2O and Mn2O3 with various Li/Mn molar ratios shows enhanced lithium storage properties. When used as the cathode for lithium ion battery, the mesoporous orthorhombic LiMnO2 has been found to exhibit a maximum discharge capacity of 191.5 mAh g-1 and a high reversible capacity of 162.6 mAh g-1 (84.9% retention) after 50 cycles at a current density of 0.1 C rate. These results demonstrate its potential application in high performance lithium-ion batteries.Keywords
