英文摘要	Nanocrystalline Li[Li0.26Ni0.11Mn0.63]O2 were easily prepared by using Ni0.15Mn0.85(OH)(2) and Li2CO3 as precursors and KCI as melt-salt for the high capacity materials of Li-ion storage. The obtained nanopartides showed same morphology of polygonal shape and the particle size distribution increased with increasing sinter temperature. The Li[Li[0.26Ni0.11Mn0.63]O2 electrode sintered at 800 degrees C for 12 h exhibits a reversible capacity of more than 300 mAh g(-1) at 0.1 C rate between 2 V and 4.8V and the capacity retention remains 86% and 90% after 90 cycles at the rate of 0.5 C and 1 C, respectively. These superior electrochemical performances are discussed in detail and ascribed to the low dimension and well-crystallized particles. The low dimension provides a short diffusion path and fast transport channels for the lithium ion insertion/extraction reactions and the well-crystallized structure restrains the elimination of oxide ion vacancies and metal ions rearrangement during charge-discharge cycling.
