“…Lithium metal generally exhibits a higher surface area, providing more sites for lithium ions to interact with the electrolyte and engage in electrochemical reactions. In contrast, the presence of lithium ions within the Gr structure reduces the effective surface area and restricts the available active sites, resulting in a lower capacity for Li‐Gr [50] …”

“…In contrast, the presence of lithium ions within the Gr structure reduces the effective surface area and restricts the available active sites, resulting in a lower capacity for Li-Gr. [50] Moreover, when comparing the Li-G and Li-Gr anodes at the same rate (Figure 5b), it is evident that the Li-G anode exhibits a capacity of only 750 mAh g À 1 , which is significantly lower than that of the Li-Gr anode. The capacity of Li-Gr/G falls in between the two.…”

Lithium‐sulfur (Li‐S) batteries are a promising candidate technology for high‐energy rechargeable batteries due to their advantages of abundant materials and inherently high energy. However, the practical applications of Li‐S batteries are challenged by several obstacles, including the low sulfur utilization and poor lifespan, which are partly attributed to the shuttle of lithium polysulfides and lithium dendrite growth during cycling.[1] The shuttling of polysulfide ions between the electrodes in a Li‐S battery is a major technical issue triggering the self‐discharge and limiting the cycle life.[2] A stable lithium anode is essential for maintaining the good cycle stability of Li‐S batteries in practical applications.[3] To address these lithium related issues, various carbon materials, including graphite and graphene, have been investigated as suitable lithium hosts to use as anode materials for Li‐S batteries.[4] In this study, prelithiated graphite and graphene‐based anode materials are obtained by galvanostatic charging method to improve the performance of Li‐S batteries and compare the electrochemical properties especially in terms of capacity retention and rate capability. According to the results, graphene showed better performance due to its high lithium storage capacity and fast lithium‐ion diffusion rate. Inductively Coupled Plasma Emission Spectrometer (ICP‐OES) results showed that the Li+ content of the graphite, graphite/graphene, and graphene electrodes measured as 26.5, 33.2, and 45.6 wt%, respectively after the lithiation process. 1 Ah pouch cell was assembled with prelithiated graphene anode showing an energy density of about 400 Wh kg−1 in the first cycle and protected its specific capacity of 60 % after 100 cycles in a liquid‐based Li‐S battery system.

“…Because of those limitations, graphene is only examined as a hybrid or nanocomposite compound or in modified form. However, it is well known that graphene could be also used as a conductive carrier and connect the active materials because of its highly good mechanical properties, thus preventing the destruction of electrode structure [ 40 ]. The three-dimensional (3D) conductive network (formed by graphene) may improve the electron and ion movement within the electrode materials [ 41 ].…”

Over the past decades, the application of new hybrid materials in energy storage systems has seen significant development. The efforts have been made to improve electrochemical performance, cyclic stability, and cell life. To achieve this, attempts have been made to modify existing electrode materials. This was achieved by using nano-scale materials. A reduction of size enabled an obtainment of changes of conductivity, efficient energy storage and/or conversion (better kinetics), emergence of superparamagnetism, and the enhancement of optical properties, resulting in better electrochemical performance. The design of hybrid heterostructures enabled taking full advantage of each component, synergistic effect, and interaction between components, resulting in better cycle stability and conductivity. Nowadays, nanocomposite has ended up one of the foremost prevalent materials with potential applications in batteries, flexible cells, fuel cells, photovoltaic cells, and photocatalysis. The main goal of this review is to highlight a new progress of different hybrid materials, nanocomposites (also polymeric) used in lithium-ion (LIBs) and sodium-ion (NIBs) cells, solar cells, supercapacitors, and fuel cells and their electrochemical performance.

“…However, because of its excellent mechanical properties, graphene can also be used as a conductive carrier and to connect active materials, preventing the destruction of electrode structures [63]. Graphene-based three-dimensional (3D) conductive networks may improve electron and ion movement within electrode materials [64]. Several studies have reported the use of reduced graphene oxide (rGO) as a hybrid component with other metal oxides; for example, an NiO/SnO 2 /rGO composite has been employed as an anode for Na-ion and Li-ion batteries, which showed a specific capacity as high as 800 mAh g −1 at a current density of 1000 mA g −1 , even after 400 cycles [65].…”

The global demand for energy is constantly rising, and thus far, remarkable efforts have been put into developing high-performance energy storage devices using nanoscale designs and hybrid approaches. Hybrid nanostructured materials composed of transition metal oxides/hydroxides, metal chalcogenides, metal carbides, metal–organic frameworks, carbonaceous compounds and polymer-based porous materials have been used as electrodes for designing energy storage systems such as batteries, supercapacitors (SCs), and so on. Different kinds of hybrid materials have been shown to be ideal electrode materials for the development of efficient energy storage devices, due to their porous structures, high surface area, high electrical conductivity, charge accommodation capacity, and tunable electronic structures. These hybrid materials can be synthesized following various synthetic strategies, including intercalative hybridization, core–shell architecture, surface anchoring, and defect control, among others. In this study, we discuss applications of the various advanced hybrid nanostructured materials to design efficient batteries and SC-based energy storage systems. Moreover, we focus on their features, limitations, and real-time resolutions.
