Notes:
The monoclinic LiMn0.9Cr0.1O2 irreversibly transforms to spinel-like structure m-LiMnO2during the electrochemical cycling. Experimental results indicated that the (440) interplanar distance ofLixMn2O4 at the charged state increases as the cycle number increases, while the (440) interplanardistance of LixMn2O4 at the discharged state decreases as the cycle number increases.A model for thetransformation of monoclinic LiMn0.9Cr0.1O2 to the spinel LiMn2O4 is suggested. According to thesuggested model, there may exist two types of s-LixMn2O4 when m-LiMnO2 transforms into s-LixMn2O4.The two types of spinel LixMn2O4 develop the nanodomain
