Various LiMn2O4 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 havemuch 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
