Abstract
It is significant to discover new environmental friendly, sustainable and renewable electrode materials for lithium-ion batteries. Manganese dicarboxylate [Mn2(pdc)2(H2O)3]n⋅2nH2O (pdc=pyridine-2,3-dicarboxylate) is firstly found to be a high-energy anode material for lithium-ion batteries. It shows a high discharge capacity of 573.7mAhg−1 for the second cycle between a 0.05 and 3.0V voltage limit at a discharge current density of 500mAg−1. The reversible capacity of 457.2mAhg−1 is remained after 100 cycles with a capacity retention being 79.6%. In addition, it is found that Mn 2,5-pyridinedicarboxyle was also stable anode materials with high capacity.
