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 mu, but increased to about 100 run with improved crystallinity after calcination at 800 degreesC 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 muA 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 (C) 2004 Elsevier B.V. All rights reserved.
