Nanostructured LiMn2O4 prepared by a glycine-nitrate process for lithium-ion batteries
نویسندگان
چکیده
Porous nanostructured spinel LiMn2O4 has been successfully synthesized using a glycine-nitrate combustion process. The average primary particle size of the as-synthesized powders was about 10 nm, but increased to about 100 nm with improved crystallinity after calcination at 800 jC for 2 h. Yet, the calcined powders were still highly porous and displayed reversible capacity of about 112 mA h g 1 at a discharge rate of 49.0 AA cm 2 (C/5 rate). At a high discharge rate of 2.44 mA cm 2 (10C rate), the obtainable reversible capacity was 57 mA h g . D 2004 Elsevier B.V. All rights reserved.

متن کاملCycling behaviour of barium doped LiMn2O4 cathode materials for Li ion secondary batteries
In order to improve the cycling performance of LiMn2O4, the spinel phase LiMn2–xBaxO4 (x = 0.01, 0.02 and 0.05) compounds were fabricated by the glycine-nitrate method. The structures of the products were investigated by X-ray diffraction. Electrochemical studies were carried out using the Li|LiMn2O4 and Li|LiMn2–xBaxO4 cells. The capacity loss of Li|LiMn2O4 cell is about 15% after 30 cycles, w...
متن کاملInitial Discharge Capacity of Manganese Cobaltite as Anode Material for Lithium Ion Batteries
Nanostructured manganese cobalt oxide spinel (MnCo2O4) are prepared by co-precipitation method and calcined at 650 and 750°C. Morphological studies show that by increasing the calcination temperature from 650 to 750°C, morphology of the particles changes from quasi-plate to polyhedral. The MnCo2O4 calcined at 650°C could deliver an initial discharge capacity of 1438 mAh g-1 under current densit...
