Resumo

<p>Copper-manganese spinel containing anodes were synthesized by a facile sol-gel method and evaluated in lithium-ion battery applications for the first time. The synergistic effects between copper-manganese and the aqueous binder (sodium carboxymethyl cellulose) provided a high specific capacity and excellent cycling performance. It was found that the specific capacity of the copper-manganese spinel remained at 608 mAh g<sup>−1</sup> after 100 cycles at a current density of 200 mA g<sup>−1</sup>. Furthermore, a relatively high reversible capacity of 278 mAh g<sup>−1</sup> could be obtained at a current density of 2000 mA g<sup>−1</sup>, indicating a good rate capability. These studies suggest that copper-manganese spinel is a promising material for lithium-ion battery applications due to a combination of good electrochemical performance and low cost.</p>
