Abstract

Ni-based coordination polymer derived from 3,3′-diaminobenzidine (Ni-DAB) is reported as a stable potassium battery anode working in the safe voltage window of 0.4–2.0 V versus K+/K. At a low current density of 50 mA g−1, specific discharge capacity of 183 mA h g−1 is reached. Capacity of 158 mA h g−1 is obtained at 1 A g−1, whereas capacity decay is only 0.014% per cycle over 600 cycles, which is among the best cycling stability results reported for electrode materials used in potassium batteries.
