Scalable Synthesis of Comn2o4 Nanorodsand their Operating-Temperature-Dependent Li-Ion Storage Behaviour

Binarytransition metal oxides have attracted increasing attention as potential anode materials for next generation lithium ion batteries.Herein, the highly temperature dependent Li-ion storage behaviours of as-produced CoMn2O4 nanorods are characterized by using cyclic voltammetry and galvanostatic charge/discharge at a wide range of operating temperature. The CoMn2O4 nanorod shows relatively higher capacity and better cyclic stability under the temperature ranged from 10 to 40 oC. Effective solutions are required to further optimize its low-temperature electrochemical activity and high-temperature cyclic stability in the future work so as to satisfy the all-weather application.
