“…However, DME-based Li-O 2 /CO 2 cells delivered a very small capacity (<50 mAh·g c –1 ) at −10 °C (Figure S5a). DMSO exhibited low cyclability at 25 °C (Figure S5b) and was unsuitable for low-temperature experiments because of its high melting point (19 °C) . For DMAc, although the first charging plateau was short at 25 °C, it performed at low temperatures owing to the low viscosity and a low melting point.…”

Lithium–oxygen (Li-O2) batteries suffer from undesirable chemical reactions. Side products, such as lithium carbonates (Li2CO3), undergo partial decomposition during charging, and their accumulation leads to poor cyclability. Herein, we show significantly improved cyclability by forming peroxodicarbonate (C2O6 2–) as the soluble discharging product, hence preserving its stability at low temperatures. The Li-O2 cells comprising 10% CO2 gas and tetraglyme electrolyte solution form anhydride-linked C2O6 2–. However, despite the improved stability of C2O6 2– at 0 °C, the low ionic conductivity of tetraglyme results in poor cyclability. In contrast, dimethylacetamide-based cells produce peroxo-linked C2O6 2– and offer over 100 cycles at −10 °C. During cycles, the first charging plateaus belonging to C2O6 2– oxidation appear consistently at 3.75 V (vs Li/Li+). In addition, Li2CO3 is entirely decomposed during the second charging plateau at 4.45 V. Our results show promise for the development of highly rechargeable Li-O2/CO2 batteries.

“…Meanwhile, to increase the carrying efficiency, hybrid carbon fillers with different geometric features have aroused people’s attention. The threadlike carbon nanotube contains a 1-D cannular structure, and graphene with a 2-D flake structure [ 28 , 29 , 30 ]. For example, Pokharel et al [ 30 ] investigated the conductive and mechanical properties of carbon-nanofiller-filled polyurethane from the points of the particle size, aspect ratio, and filler morphology.…”

The current work studied the physical modification effects of non-covalent surfactant on the carbon-particle-filled nanocomposite. The selected surfactant named Triton™ X-100 was able to introduce the steric repelling force between the epoxy matrix and carbon fillers with the help of beneficial functional groups, improving their dispersibility and while maintaining the intrinsic conductivity of carbon particles. Subsequent results further demonstrated that the physically modified carbon nanotubes, together with graphene nanoplates, constructed an effective particulate network within the epoxy matrix, which simultaneously provided mechanical reinforcement and conductive improvement to the hybrid nanocomposite system. For example, the hybrid nanocomposite showed maximum enhancements of ~75.1% and ~82.5% for the quasi-static mode-I critical-stress-intensity factor and dynamic compressive strength, respectively, as compared to the neat epoxy counterpart. Additionally, the fine dispersion of modified fillers as a double-edged sword adversely influenced the electrical conductivity of the hybrid nanocomposite because of the decreased contact probability among particles. Even so, by adjusting the modified filler ratio, the conductivity of the hybrid nanocomposite went up to the maximum level of ~10−1–100 S/cm, endowing itself with excellent electro-thermal behavior.

High-damping rubber composites were prepared by mixing ethylene propylene diene monomer rubber (EPDM) with slide-ring (SR) materials using a two-roll mill, followed by a compression molding technique. SR material has a novel supramolecular structure with unique softness and slidable crosslink junctions. The mechanical strength, thermal stability, compression set property, and damping performance of the composites were investigated. The use of the high damping SR phase dispersed in the EPDM matrix displayed improved physical properties and damping performance compared to those of virgin rubber. As SR content increases in the composites, the damping factor of SR/EPDM blends becomes higher at room temperature. In addition to this, the SR composites showed excellent improvements in the compression set properties. The composites showed a compression set improvement of 35–38% compared to virgin EPDM. These improvements are due to the “pulley effect” of slide-ring materials. Therefore, these materials present a robust platform for making novel elastomer composites for high-performance damping and sealing applications.
