Spinel-to-CaFe2O4-type structural transformation in LiMn2O4 under high pressure.
A new form of LiMn2O4 is reported. The structure is the CaFe2O4-type and 6% denser than the spinel. The structure transformation was achieved by heating at 6 GPa. Analysis of the neutron diffraction pattern confirmed an average of the structure; the unit cell was orthorhombic at a = 8.8336(5) angstroms, b = 2.83387(18) angstroms, and c = 10.6535(7) angstroms (Pnma). Electron diffraction pattern...
متن کاملUltrathin spinel LiMn2O4 nanowires as high power cathode materials for Li-ion batteries.
Ultrathin LiMn(2)O(4) nanowires with cubic spinel structure were synthesized by using a solvothermal reaction to produce α-MnO(2) nanowire followed by solid-state lithiation. LiMn(2)O(4) nanowires have diameters less than 10 nm and lengths of several micrometers. Galvanostatic battery testing showed that LiMn(2)O(4) nanowires deliver 100 and 78 mAh/g at very high rate (60C and 150C, respectivel...

متن کاملSpinel LiMn2O4 nanorods as lithium ion battery cathodes.
Spinel LiMn2O4 is a low-cost, environmentally friendly, and highly abundant material for Li-ion battery cathodes. Here, we report the hydrothermal synthesis of single-crystalline beta-MnO2 nanorods and their chemical conversion into free-standing single-crystalline LiMn2O4 nanorods using a simple solid-state reaction. The LiMn2O4 nanorods have an average diameter of 130 nm and length of 1.2 mic...
