The newly synthesized organic 2,2'-bipyridine-5,5'-potassium dicarboxylate shows a high specific capacity in potassium-ion batteries, surpassing most reported K-storage anode materials.
A novel organic 2,2'-bipyridine-5,5'-potassium dicarboxylate (K2C12H6N2O4) was designed and synthesized as an anode material in potassium-ion batteries. Multiple active sites and large pi-conjugated plane molecular structure promote K(2)C(12)H(6)N(2)O(4 )to exhibit a high specific capacity of 840 mAh g(-1) at 20 mA g(-1), which exceed most of the reported K-storage anode materials.
