High capacity positive electrodes for secondary Mg-ion batteries
Abstract
<p>Composites of layered structured Birnessite-MnO <sub>2</sub> and tunnel structured Hollandite-MnO <sub>2</sub> in presence of acetylene black were synthesized as positive electrode materials for rechargeable Mg-ion batteries. Reversible insertion/extraction of Mg-ion in the host structures was examined in the potential range of -1.8 to 1.0 V vs. Ag/Ag <sup>+</sup>. Results indicated that Mg-ion exchanged Birnessite/acetylene black composite showed the highest discharge capacity (109 mAh g <sup>-1</sup>) at 1st discharge, when compared to other microstructures of Birnessite. Meanwhile, the composite comprising of 65 wt% Hol-MnO <sub>2</sub> and 35 wt% acetylene black showed very high insertion of Mg-ion (0.87 Mg/Mn) corresponding to discharge capacity of 475 mAh g <sup>-1</sup> when tested at 60°C in galvanostatic mode. The layered and tunneled framework of the MnO <sub>2</sub> was retained with minor displacive adjustments even after substantial Mg-ion insertion/extraction after several cycles. However, large specific capacity loss was observed after 20 cycles in all of the microstructures probably due to Mg-ion trapping in the host lattice. Furthermore, the effect of the cation (K <sup>+</sup>) present in the tunnel of Hollandite on Mg-ion diffusion was analyzed as well and it was concluded that tunnel cation could impede the movement of Mg-ion in host structure.</p>
