3.2.Effects of heating temperature on the electrochemical
properties of LiMn2O4
3.2.1.Cyclic voltammetry behaviour
The electrochemical properties of spinel LiMn2O4 are
strongly affected by the heating process.Figure 7
presents the voltammograms of various LiMn2O4 samples
obtained at the same sprinkler rotation speed of
15 000 rpm but different heating temperatures.The
synthesis temperatures for curves (a)–(d) were 250,
650,700 and 800 \1C,respectively.All curves demonstrate
the electrochemical characteristics of spinel
LiMn2O4.Two couples of redox current peaks located
at about 3.95 V/4.08 V and 4.05 V/4.20 V appear on
each curve.They correspond to a two-step reversible
intercalation reaction,in which lithium ions occupy twodifferent tetragonal 8a sites in spinel LixMn2O4 (x < 1 )
[16,17].The spinel LiMn2O4 could be formed at low
temperature 250 \1C,but its redox current peaks were
relatively low as shown on curve (a) in Figure 7.The
observation reveals that the solid state reaction at
250 \1C was not complete.Among them the submicrosized
LiMn2O4 formed at 700 \1C presents the best
performance as shown on curve (c):well separated two
peaks and with highest peak current.The loss of
electrochemical activity of sample formed at 800 \1C
may be attributed to the structure change.The compound
heated at higher temperature may contain some
tetragonal LiMn2O4,which presents less electrochemical
activity [18].
