Special Issue Information

Dear Colleagues,

Two-dimensional (2D) materials (e.g., graphene, MXene, transition metal dichalcogenide (TMD) nanosheets) have been recognized as a unique category of materials which not only perform metal-like superior physicochemical properties (e.g., electrical, mechanical, chemical) but also exhibit advantages such as good processability, low density, high flexibility as soft materials do (e.g., polymer, hydrogel). This uniqueness enables the promising application of 2D materials in electronic systems to embed enhanced functionalities along with significantly improved mechanical flexibilities, which are demanded by traditional “hard” electronics with restricted application scenarios.

On the other hand, with the introduction of 2D materials into traditional material systems, various candidates and fabrication approaches have been involved. The conventional trial-and-error principle could be extremely time- and resource-consuming considering the huge parameter space involved (e.g., type, property, concentration, integration approach). Meanwhile, the data processing and analysis of certain electronic systems (e.g., full body tracking, biosensing, health monitoring) create heavy workload as well due to the huge amount of data collected and noise signals involved at the same time.

The current Special Issue focuses on (1) next-generation 2D materials integrated smart electronics with diverse functionalities and applications in fields including health monitoring, motion tracking, electronic skin, soft robotics, and more; (2) efficient approaches to accelerate the materials exploration/fabrication and data processing for 2D materials integrated electronics with the help of artificial intelligence and big data.

In this article, we present the performance of Copper (Cu)/Graphene Nano Sheets (GNS) and C—π (Graphite, GNS, and Nitrogen-doped Graphene Nano Sheets (N—GNS)) as a new battery electrode prototype. The objectives of this research are to develop a number of prototypes of the battery electrode, namely Cu/GNS//Electrolyte//C—π, and to evaluate their respective performances. The GNS, N—GNS, and primary battery electrode prototypes (Cu/GNS/Electrolyte/C—π) were synthesized by using a modified Hummers method; the N-doped sheet was obtained by doping nitrogen at room temperature and the impregnation or the composite techniques, respectively. Commercial primary battery electrodes were also used as a reference in this research. The Graphite, GNS, N—GNS, commercial primary batteries electrode, and battery electrode prototypes were analyzed using an XRD, SEM-EDX, and electrical multimeter, respectively. The research data show that the Cu particles are well deposited on the GNS and N—GNS (XRD and SEM—EDX data). The presence of the Cu metal and electrolytes (NH4Cl and MnO2) materials can increase the electrical conductivities (335.6 S cm−1) and power density versus the energy density (4640.47 W kg−1 and 2557.55 Wh kg−1) of the Cu/GNS//Electrolyte//N—GNS compared to the commercial battery (electrical conductivity (902.2 S cm−1) and power density versus the energy density (76 W kg−1 and 43.95 W kg−1). Based on all of the research data, it may be concluded that Cu/GNS//Electrolyte//N—GNS can be used as a new battery electrode prototype with better performances and electrical activities.
