“…[70] The detail chemistry of organic (or inorganic) liquid electrolytes and solid state electrolytes as well as additives have been discussed in review articles [35,[71][72][73][74][75][76][77][78][79] and they refer to four major types of nonaqueous electrolytes such as organic liquids with Li salts, gel polymer electrolytes, solid electrolytes and ionic liquids. [72] Solid electrolytes have obvious advantages and disadvantages: they have excellent chemical and physical stability but low ionic conductivity, limited contact area with nanostructured electrode materials and suffer from interfacial stress due to volume changes of the electrodes during cycling.…”

“…With this concept, two different types electrolytes could complement each other; for example, achieving better physical and chemical stability with good ionic conductivity. [73] On the other hand, ionic liquids, especially room temperature ionic liquids (RTIL) are structurally composed of anions and cations, which interact with each other due to Coulombic forces. Because of strong Coulombic forces, they typically exhibit high viscosity, high anodic stability and low vapor pressure resulting in lack of flammability.…”

Light metals have been widely used as electrode materials for batteries owing to their low standard redox potential, their low equivalent weight, large specific capacity, and great abundance. Both primary and secondary cells including light metals as electrode material have influenced all aspects of our lives, e.g., electrically operated toys, power tools, and portable electronics such as cell phones, smart pads, and laptop computers. Among all battery systems, rechargeable lithium (Li) ion cells have been used most widely in recent years owing to their high specific power, high energy density, and ambient temperature operation. However, Li‐ion cells are facing difficult challenges in satisfying the emerging market for advanced applications demanding high‐performance rechargeable batteries for applications such as electric vehicles, high‐performance portable electronics, and large‐scale electrical energy storage systems. Unfortunately, current Li‐ion cells cannot satisfy demands such as low cost, much improved safety, larger energy density, faster charge/discharge rates, and longer service life, so intensive effort is necessary to develop the next generation of cells. In this article, the limitations of current Li‐ion cells and various advanced materials for each component of the Li‐ion cell, in addition to other promising candidates for cells beyond Li ion, such as the Li/S cell and Na‐ and Mg‐based rechargeable cells, and metal/air cells are discussed.

“…For instance, extensive research has been done to improve the electrical conductivity of the cathode and to trap the sulfur and polysulfides in a carbon matrix. For example, carbon matrices (i.e., porous carbons [6], carbon nanotubes [7], hollow carbon [8], carbon fibers [9], ordered mesoporous carbon [10], hierarchical porous carbon [11] and graphene nanosheets (GNS) [12] have been investigated to improve electrochemical performance by increasing the utilization of the sulfur cathode. Among these carbon materials, GNS can open new possibilities because of their high electrical conductivity, superior mechanical flexibility, high chemical and thermal stability, high surface functionality, and large surface area [13][14][15][16][17][18][19].…”

Due to their morphology, electrochemical stability, and function as a conducting carbon matrix, graphene nanosheets (GNS) have been studied for their potential roles in improving the performance of sulfur cathodes. In this study, a GNS/sulfur (GNS/S) composite was prepared using the infiltration method with organic solvent. The structure, morphology and crystallinity of the composites were examined using scanning electron microscopy, transmission electron microscopy, and X-ray diffraction. The electrochemical properties were also characterized using cyclic voltammetry (CV). The CV data revealed that the GNS/S composites exhibited enhanced specific-current density and ~10% higher capacity, in comparison with the S-containing, activated-carbon samples. The composite electrode also showed better cycling performance for multiple charge/discharge cycles. The improvement in the capacity and cycling stability of the GNS/S composite electrode is probably related to the fact that the graphene in the composite improves conductivity and that the graphene is well dispersed in the composites.

“…To overcome this, polymer electrolytes were introduced that plays an essential role in rechargeable lithium ion batteries. Hence, the control of the miscibility and stability between the liquid electrolytes and the host polymer itself has become one of the prominent factors for polymer electrolytes [3]. Indeed, microporous structure of the host polymer matrix is one of the convenient tools for ionic transport and enhances ionic conduction [4].…”

Composite microporous membranes based on Poly (vinylidene fluoride-co-hexafluoro propylene) P(VdF-co-HFP)-CeO 2 were prepared by phase inversion and preferential polymer dissolution process. It was then immersed in 1M LiClO 4 -EC/DMC (v/v = 1 : 1) electrolyte solution to obtain their corresponding composite microporous membrane electrolytes. For comparison, composite membrane electrolytes were also prepared by conventional phase inversion method. The surface morphology of composite membranes obtained by both methods was examined by FE-SEM analysis, and their thermal behaviour was investigated by DSC analysis. It was observed that the preferential polymer dissolution composite membrane electrolytes (PDCMEs) had better properties, such as higher porosity, electrolyte uptake (216 wt%), ionic conductivity (3.84 mS·cm −1 ) and good electrochemical stability (4.9 V), than the phase inversion composite membrane electrolytes (PICMEs). As a result, a cell fabricated with PDCME in between mesocarbon microbead (MCMB) anode and LiCoO 2 cathode had better cycling performance than a cell fabricated with PICME.
