Porous Carbon Derived from Metal-Organic Framework as an Anode for Lithium-Ion Batteries with Improved Performance

摘要：

　　A facile two-step method for preparation of porous carbon materials was reported.We used a novel Co-MOF, made by cobalt nitrate and two organic ligands (9-ethylcarbazole-3,6-dicarboxylic acid and 1,3,5-Benzenetricarboxylic acid), as the template to synthesize the porous carbon through high temperature carbonization, which was applied as an anode material for lithium-ion batteries.A reversible capacity was maintained as high as 549 mA h g-1 after 49 cycles at a current density of 100 mA g-1, with coulombic efficiency of over 95%.The prepared porous carbon electrode also exhibited superior cycle stability and rate performance, making it a promising anode material for lithium-ion batteries.
