摘要：

A lithium-organic coordination compound based on an aromatic carbonyl derivative, [Li-2(C14H6O4)], was synthesized by the dehydration of [Li-2(C14H6O4)center dot H2O], and used as a novel lithium-inserted material for lithium ion batteries. The synthesized material has initial discharge capacity of 126 and 115 mAh/g at current densities of 22 and 111 mAh/g, corresponding to the columbic efficiency of 99.2% and 983% at the first cycle, and its capacity fading is only 5% and 13% after 50 cycles, respectively, showing that this compound is a promising candidate as lithium-inserted material for lithium ion batteries.
