Herein, the effect of the size of Mg clusters on graphene nano sheets (GNS) and N-GNS (C-π) is investigated. The dependence of the electric conductivities of C-π on the electrolytes was also explored. This work aims to clarify the size effect of Mg clusters on Mg/C-π and to study the effect of addition of electrolytes to C-π materials on their electrical conductivities and chemical interaction between Mg on GNS and N-GNS, respectively. GNS and N-GNS are synthesized by modified Hummers and N-dopant method at room temperature, respectively. Characterization of each material is carried out using X-ray diffraction (XRD), scanning electron microscope–energy dispersive X-ray (SEM–EDX), and multimeter. The results show that the Mg cluster are well deposited on GNS and N-GNS and the addition of Mg metal and electrolyte materials can increase the electrical conductivities of Mg/GNS (69.9301 μS cm⁻¹) and Mg/N-GNS (96.1538 μS cm⁻¹), comparing to graphite (26.7 μS cm⁻¹) and anode of commercial battery (26.0 μS cm⁻¹). The addition of electrolyte can also increase the reduction power of Mg metal particles and the electron mobility of Mg/GNS and Mg/N-GNS materials. Interestingly, the electrolyte could reduce the size of Mg clusters and modulate the mobility of electrons. Data conclude that Mg/GNS and Mg/N-GNS can be produced into battery electrodes with better electrical conductivity.

基于Mg/C-π的新材料电池

在此，研究了 Mg 团簇的尺寸对石墨烯纳米片 (GNS) 和 N-GNS (C- π ) 的影响。还探讨了 C- π 的电导率对电解质的依赖性。本工作旨在阐明 Mg 团簇对 Mg / C- π的尺寸效应，并研究添加电解质对 C- π 的影响分别对 GNS 和 N-GNS 上的 Mg 之间的电导率和化学相互作用进行了研究。GNS 和 N-GNS 分别在室温下通过改进的 Hummers 和 N-dopant 方法合成。使用 X 射线衍射 (XRD)、扫描电子显微镜 - 能量色散 X 射线 (SEM - EDX) 和万用表对每种材料进行表征。结果表明，Mg 团簇在 GNS 和 N-GNS 上沉积良好，添加 Mg 金属和电解质材料可以提高 Mg / GNS (69.9301 μS cm ^-1 ) 和 Mg / N-GNS (96.1538 μS) 的电导率cm ^-1 )，与石墨 (26.7 μS cm ^-1 ) 和商业电池的阳极 (26.0 μS cm ^-1）。电解液的加入还可以提高Mg金属颗粒的还原能力和Mg/GNS和Mg/N-GNS材料的电子迁移率。有趣的是，电解质可以减小 Mg 簇的尺寸并调节电子的迁移率。数据表明，Mg/GNS 和 Mg/N-GNS 可以制成具有更好导电性的电池电极。
