Lithium Manganese Oxide LiMn2O4 Spinel Powder For Li-ion Battery Cathode
Lithium Manganese Oxide (LiMn2O4) Spinel Cathode has the chemical formula of LiMn2O4. It has a spinel structure (space group Fd3m). In addition to containing inexpensive materials, the three-dimensional structure of LiMn2O4 lends it self to high rate capability by providing well connected framework for the insertion and de-insertion of Li+ ions during discharge and charge of the battery. In particular, the Li+ ions occupy the tetrahedral sites within the Mn2O4 polyhedral frameworks adjacent to empty octahedral sites. Because of this structural arrangement, lithium ion batteries based on LiMn2O4 cathodes have demonstrated a higher rate-capability compared to materials with two-dimensional frameworks for Li+ diffusion.
