Binders play a critical role in stabilizing the sulfur cathode of Li-S and Na-S batteries. Over the past decade, the design of binder molecules has gone through tremendous evolution from primarily maintaining the structural integrity of the electrode against volume change to rationally immobilizing polysulfide intermediate and facilitating electron/ion transport in the charge and discharge process. This article reviews the development of binder for Li-S and Na-S batteries from the perspective of molecular design, and comprehensively discusses the correlation between the functions of the binder molecules and the cell performance. It also points out the future challenge and the potential solutions to address them. Figure 2. Timeline of the development of binders in terms of specific functions in Li-S and Na-S batteries. The binder in Li-S batteries has experienced a remarkable evolution in terms of functions, from fundamental structural and mechanical stabilizer (linear, hybrid, [30] dendrimer, [31] and crossedlinked binder [32,33] ) to versatile functions of polysulfide immobilization (polymer with functional groups [34][35][36] or cation groups [37] ) and facilitation of electron transport on the basis of conductive polymer. [38,39] It opens up the research of multifunctional binder. The analogous development route in the binder is found in Na-S batteries. [40,41] Reproduced with permission. [30]

“…Due to their high conductivity and high aspect ratio, the graphene-based composites and 2D carbon sheets materials have been widely used as electrode materials for supercapacitors. [65] However, graphene easily restacks due to the π-bond interaction to form lamellar microstructure on the current collectors during the electrode fabrication process. [66] The restacking of the graphene sheets limits the electron and mass transport at the electrode interface, reducing the utilization of electrode materials and leading to the poor electrochemical performance of supercapacitors.…”

Supercapacitors, as a type of energy storage system, bridge the power/energy gap between conventional capacitors and batteries due to attractive properties such as high power density, long cycle lifespan, and large temperature range. However, the low energy density of supercapacitors compared to lithium‐ion batteries has hindered their general application. In general, the electrochemical performance of supercapacitors is closely related to the structure of their electrode materials, electrolytes, and device design. The main materials used in electrochemical double‐layer capacitors (EDLCs) are carbon materials with various architectures. This is due to their high surface area, good electric conductivity, and intrinsic stability. In this review, recently reported carbon‐based nanostructured electrode materials with 0D, 1D, 2D, and 3D structures are systematically reviewed. The effect of nanostructuring on the properties of supercapacitors including specific capacitance, rate capability, and cycle stability is explored, the details of which may serve as a guide to electrode design for the next generation of EDLCs.
