To meet the growing demand in energy, great efforts have been devoted to improving the performances of energy–storages. Graphene, a remarkable two-dimensional (2D) material, holds immense potential for improving energy–storage performance owing to its exceptional properties, such as a large-specific surface area, remarkable thermal conductivity, excellent mechanical strength, and high-electronic mobility. This review provides a comprehensive summary of recent research advancements in the application of graphene for energy–storage. Initially, the fundamental properties of graphene are introduced. Subsequently, the latest developments in graphene-based energy–storage, encompassing lithium-ion batteries, sodium-ion batteries, supercapacitors, potassium-ion batteries and aluminum-ion batteries, are summarized. Finally, the challenges associated with graphene-based energy–storage applications are discussed, and the development prospects for this field are outlined.

“…Further, the creation of a conducting medium with active material permits a maximum number of lithium ions between the nanoarchitectonic matrix, which altogether brings a better electrochemical performance. 38 This report comprises the synthesis of core−shell manganese ferrites (CSMF) via a simple but effective sonoelectrochemical method, and it was incorporated into the self-assembled reduced graphene matrix (CSMF/rGO) to form a hybrid nanoarchitectonic layered structure. The prepared CSMF/rGO nanocomposite was used as an anode in the Li-ion cell to study the improvements in specific capacitance at different current densities, quick stable SEI layer formation, and high-rate performance for longer cycles.…”

With the considerations of attaining high-capacity anode material for longer cycles at a high charge−discharge rate, in this work, a facile core−shell manganese ferrite/reduced graphene oxide (CSMF/rGO) was fabricated in situ through a rapid two-step ultrasonication method. For that, the CSMF was synthesized by adopting a simple but effective electrochemical method with ultrasound assistance. The prepared three-dimensional network of CSMF was incorporated into the self-assembled graphene matrix by in situultrasonication to form a hybrid nanoarchitectonic composite (CSMF/rGO). The coupled effect of redox reactions and ultrasonic cavitation for the formation of CSMF/rGO were discussed. The self-assembled hybrid nanoarchitectonic structure has the beneficial features of tight-packing configuration, which resolves the volume expansion−contraction nature of magnetite and simultaneously provides improvement for the movement of lithium ions and electrons during charge−discharge cycles. As a result, the CSMF/rGO electrode delivers a high initial discharge capacity of 1512 mAh g −1 at 0.2 A g −1 current density and provides a better reversible capacity of 492 mAh g −1 at a high-current density of 2.0 A g −1 after 500 cycles with high Coulombic efficiency (>99%). The results of this report would be helpful to design a CSMF/rGO hybrid electrode as a new-gen anode for the utilization of lithium-ion batteries under an economic and rapid synthesis method.

The best choice today for a realistic method of increasing the energy density of a metal-ion battery is to find novel, effective electrode materials. In this paper, we present a theoretical investigation of the properties of two-dimensional B3C5 and N3C5 bilayer systems as potential anode materials for lithium-ion batteries. The simulation results show that N3C5 bilayer is not suitable for anode material due to its thermal instability. On the other hand B3C5 is stable, has good electrical conductivity, and is intrinsically metallic before and after lithium intercalation. The low diffusion barrier (0.27 eV) of Li atoms shows a good charge and discharge rate for B3C5 bilayer. Moreover, the high theoretical specific capacity (579.57 mAh/g) connected with moderate volume expansion effect during charge/discharge processes indicates that B3C5 is a promising anode material for Li-ion batteries.
