摘要
The electrochemical properties of LiCr 0.1 Mn 1.9 O 4 as a cathode material in five electrolyte solutions , LiPF 6/EC+DEC, LiPF 6/EC+EMC, LiPF 6/EC+DME, LiPF 6/EC+DMC and LiBF 4/ EC+ DMC have been studied. The initial capacity values were very close each to other for the electrolyte solutions examined. However, the capacity fading and self discharge data obtained from the cells with above electrolyte solutions were different in the order of LiPF 6/EC+DME>LiPF 6/EC+EMCLiPF 6/EC+DMC≈LiPF 6/EC+DEC≈LiBF 4/EC+DMC. Decrease of the electrochemical properties was attributed mainly to the electrolyte decompositions on the surface of the electrodes. LiPF 6/EC+DEC, LiPF 6/EC+DMC and LiBF 4/EC+DMC appeared electrolytes well compatible with LiCr 0.1 Mn 1.9 O 4 electrode.
