Abstract

We report the synthesis of porous CoMoO4 nanorods and their applications in lithium oxygen (Li–O2) and lithium ion (Li-ion) batteries. The unique porous structures of CoMoO4 nanorods can promote the permeation of electrolyte and benefit the transport of lithium ion. When employed as the cathode catalyst for a Li–O2 battery, CoMoO4 nanorods deliver an improved discharge capacity (4680 mA h g−1), lower charge potential and better cycle stability (41 cycles at 500 mA h g−1 capacity limit) compared with the bare carbon. When employed as an anode in Li-ion batteries, CoMoO4 nanorods can retain a capacity of 603 mA h g−1 after 300 cycles (400 mA g−1) and exhibit excellent rate capability.
