摘要：

Nanocomposites of spinel LiMn2O4 and carbon nanotubes (CNTs) were in-situ prepared via a simple hydrothermal method by using MnO2/CNT and LiOH as reaction agent. The obtained composites demonstrated a homogenous dispersing of CNTs and LiMn2O4 nanocrystals, which combined both the advantages of the good crystallinity of LiMn2O4 and the excellent electron conductivity of CNTs. The LiMn2O4/CNT nanocomposites showed a good rate behavior and an excellent cycling retention for lithium ion batteries. A reversible discharge capacity of 115 mAh g(-1) at 1 C discharge rate based on the weight of LiMn2O4 was obtained. The good capacity retention nearly to 100% upon 100 cycles indicated that the LiMn2O4/CNT nanocomposites could act as promising cathode materials for lithium ion batteries. (C) 2011 Elsevier B.V.
