It is important to discover new, cheap and environmental friendly coordination polymer electrode materials for lithium-ion batteries. Zinc 2,6-pyridilinedicarboxylate particles show better cycling stability and higher discharge capacity than 2,5-pyridilinedicarboxylate micro-platelets when they are firstly tested as anode materials for lithium-ion batteries. The former can steadily cycle at current densities of 750, 1000 and 2000 mA g(-1). It is also stable in multiple insertion/extraction processes at current densities of 750, 1500, 2000, 2500, 3000, and 750 mA g(-1), and the capacity retention is 77.9% after 60 cycles. While the latter is apt to show good cycling performance at smaller discharge current density. (C) 2016 Elsevier Inc. All rights reserved.
