The New Material Battery Based on Mg/C‐π

Abstract

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.
