“…The conductivity enhancement in polymer‐SCEs is also believed to be at least in part a result of interface interactions. The interaction between the inorganic particles can suppress the crystallinity of the polymer thus lowering the T g of the polymer as supported by nuclear magnetic resonance (NMR), X‐ray powder diffraction (XRD), and differential scanning calorimetry (DSC) results. A polymer can consist of crystal and/or amorphous parts .…”

The development of solid composite electrolytes or solid composite electrolytes (SCEs) consisting of an ionic conductor and a dielectric matrix offers an elegant strategy to enhance the ionic conductivity of electrolytes by engineering the interface conduction. At the conductor/matrix interface, the ionic conductivity can be enhanced by the enriched charge carrier concentration and/or the changed molecular structure of the ionic conductor. This review deals with the interfacial ion conduction mechanisms of the inorganic particle‐based SCE, polymer‐SCE, and ionic liquid electrolyte‐based SCE (ILE‐SCE). In the first part of this review, an overview is given of the space‐charge theory developed to describe the increased vacancy concentration at the interface of inorganic particle‐based SCE. In the second part, the proposed interface interactions and structural changes associated with interface conduction for the polymer‐SCE and ILE‐SCE are reviewed. For the ILE‐SCE, the preparation methods and interface characterization are discussed together with the proposed conductivity models. The use of mesoporous matrix materials with high internal surface area for ILE‐SCE is reviewed here for the first time.

“…In this regard, the replacement of liquid electrolytes by solid or quasi‐solid polymer electrolytes has been considered a viable method for avoiding the loss of active materials . For this purpose, inorganic electrolytes (e.g., solid oxide electrolytes and solid sulfide electrolytes) are promising candidates, as they can exhibit high conductivities despite being solids . Although good rate performance was provided by the inherent single‐ion conducting characteristics of inorganic electrolytes, the high cost, high volumetric mass density, lack of flexibility, and limited processability of such materials remain fatal drawbacks for the preparation of future batteries with various form factors …”

Advances in lithium battery technologies necessitate improved energy densities, long cycle lives, fast charging, safe operation, and environmentally friendly components. This study concerns lithium–organic batteries comprising bioinspired poly(4‐vinyl catechol) (P4VC) cathode materials and single‐ion conducting polymer nanoparticle electrolytes. The controlled synthesis of P4VC results in a two‐step redox reaction with voltage plateaus at around 3.1 and 3.5 V, as well as a high initial specific capacity of 352 mAh g−1. The use of single‐ion nanoparticle electrolytes enables high electrochemical stabilities up to 5.5 V, a high lithium transference number of 0.99, high ionic conductivities, ranging from 0.2×10−3 to 10−3 S cm−1, and stable storage moduli of >10 MPa at 25–90 °C. Lithium cells can deliver 165 mAh g−1 at 39.7 mA g−1 for 100 cycles and stable specific capacities of >100 mAh g−1 at a high current density of 794 mA g−1 for 500 cycles. As the first successful demonstration of solid‐state single‐ion polymer electrolytes in environmentally benign and cost‐effective lithium–organic batteries, this work establishes a future research avenue for advancing lithium battery technologies.

All-solid-state lithium-sulfur batteries (ASSLSBs) offer a means to enhance the energy density and safety of the state-of-art lithiumion batteries (LIBs), due to their high gravimetric energy density, low cost and environmental benignancy. In this work, the status of the research advances and perspectives on several types of solid electrolytes (SEs) developed for ASSLSBs are reviewed. The promises and challenges of utilizing SEs are discussed taking into account both theoretical calculation and experimental results, in hope of shedding some lights on future design of high energy density, cost competitive, and safe Li-S batteries. Lithium-sulfur (Li-S) batteries have been extensively investigated for lightweight applications (e.g., aircraft, artificial satellite, and unmanned aerial vehicles), and large-scale stationary energy storage, owing to their high gravimetric energy density, low cost, and environmental friendliness.1-3 The deployment of Li-S batteries into commercial market is hampered by several seemingly intrinsic problems resulting from the complex cell chemistry. Firstly, the electronically insulating nature of elemental sulfur (S 8 ) and end-product lithium sulfide (Li 2 S) leads to unstable electrochemical contact within S cathode. [4][5][6][7] Secondly, the soluble intermediates of polysulfide (PS) can diffuse between the cathode and anode (i.e., shuttle effect of PS), generating an active material loss in S cathode and degrading metallic Li anode. [4][5][6][7][8][9] Thirdly, the formation of 'dead' Li and Li dendrites upon cycling could not only decrease the Coulombic efficiency but also raise safety issues. [10][11][12] In recent years, various strategies have been attempted to overcome the above-mentioned problems. Most of the efforts have been devoted to enhance the electrochemical performance of Li-S batteries using well-designed cathode materials. 13 The diffusion of polysulfide species generated during discharge into electrolytes can be significantly suppressed by infusing sulfur into carbon materials in the cathode with an adequately controlled and engineered porosity and pore size, thus increasing the practical capacity and cyclability of Li-S batteries. These rational and creative strategies of cathode design have been covered by a number of recent reviews. 7,14,15 Besides, new binders (e.g., poly(ethylene oxide) (PEO) 16 and carboxymethycellulose (CMC) 17,18 ) have been employed for guarantying the integrity of the morphology and structure of S cathode, and enhancing the adhesion to current collector. The modification of separators (e.g., multiwall carbon nanotubes coated polypropylene 19 and lithiated Nafion 20 ) have been also developed for reducing the migration of polysulfides, thus mitigating the shuttle effect of PS. 21Apart from the strategies mentioned above, another approach, focusing on electrolyte formulation and modification, has been proved to be effective. The performances of Li-S batteries are largely affected by the electrolyte recipes, such as the type and identity of so...
