Optimization of the Synthesis Procedure of LiMn 2 O 4 Electrodes for Efficient Rechargeable Lithium Cells: Influence of the Crystallite Size and Surface Defects on the Electrochemical Performances of 3 V Li 1+x Mn 2 O 4 and 4V Li 1-x Mn 2 O 4 Electrodes

Various LiMn 2 O 4 electrode materials, having different crystallite sizes ranging from ∼50Å to ∼500Å, have been investigated either in 3V or in 4V Li batteries. In agreement with our ≪electrochemical model≫, we have shown that nanocrystalline samples have much higher capacity, and cyclability than...

Description
Summary:Various LiMn 2 O 4 electrode materials, having different crystallite sizes ranging from ∼50Å to ∼500Å, have been investigated either in 3V or in 4V Li batteries. In agreement with our ≪electrochemical model≫, we have shown that nanocrystalline samples have much higher capacity, and cyclability than their microcrystalline homologue in the 3 V domain uniquely. A reverse trend is observed in the 4 V range, still in agreement with the model.
