“…[53] A similar hybrid consisting of CMC and nitrilebutadiene rubber hybrid binder (CMC/NBR) was also reported later. [65,72] It provides sufficient carboxyl moieties for good adhesion to sulfur species and easily undergoes ionic cross-linking when introducing Ga 2+ . Branch-type structures possess more functional groups than linear polymers, which improve the adhesive ability of the binder.…”

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]

“…For example, the insulating character of sulfur (S 8 ) and lithium sulfi de (Li 2 S) impede the full electrochemical utilization of sulfur. [43][44][45][46] Inspired by the previous work where the Naalginate binder was used to stabilize the sulfur electrode, [47][48][49][50] we selected the chitosan binder in our electrode formulations in order to reduce the electrode volume expansion and loss of active material caused by dissolved lithium polysulfi des. [11][12][13][14] Other issues such as low Coulombic effi ciency, high self-discharge, and huge volume change remain unsolved.…”

“…Wang et al [57] added chemically oxidized b-cyclodextrin (b-CD) into water-soluble carbonyl-bcyclodextrin (C-b-CD), and used C-b-CD as the binder for a SPAN-based cathode. Other water-soluble or water-dispersible binders include Na-alginate [58], polyacrylic acid (PAA) [59], poly(acrylamideco-diallyldimethylammonium chloride) (AMAC) [60], styrene-butadiene rubber (SBR)-carboxymethyl cellulose (CMC) [61,62], and PTFE/CMC [63].
