An integrated highly stable anode enabled by carbon nanotube-reinforced all-carbon binder for enhanced performance in lithium-ion battery

Determination of Hansen Solubility Parameter and In Situ Visualization of Dispersion Stability of Solution-Processed Antimonene

“…During the charging and discharging process, Sb undergoes tremendous volume expansion due to the alloying of Li + with Sb, as a result of which pulverization of electrodes occurs, hampering the stability of the Sb anode . In literature, CNT has been used to address the volume expansion issues of various anode materials. − In this context, to improve the battery performances of Sb-based LIBs, f-CNT has been integrated with antimonene, and the battery performance of the composite has been evaluated in the half-cell configuration. The formation of the composite is confirmed by employing various characterization techniques.…”

Improving the Sodium Storage Performance of Porous Carbon Derived From Covalent Organic Frameworks Through N, S Co-Doping

“…First, the initial three curves of the NSC-600 electrode at the scan rate of 0.2 mV s −1 from 0.005 to 3.0 V are depicted in Figure 3A. The irreversible cathodic peak at around 0.88 V presented in the first cathodic scan, which is disappeared in the subsequent scans, should be ascribed to the decomposition of electrolyte to passivate the surface as well as the generation of solid electrolyte interface (SEI) (Eshetu et al, 2019;Cheng et al, 2021;Fan et al, 2021). In addition, another broad cathodic peak in the low voltage from 0.71 V to 0.005 V should be ascribed to the intercalation of Na + into the carbonaceous skeleton (Kumar et al, 2016).…”

Preparation of a Flexible Reduced Graphene Oxide-Si Composite Film and Its Application in High-Performance Lithium Ion Batteries

“…The rGO@Si NPs composite films were prepared from a GO aqueous dispersion. A modified version of the Hummers process was used to produce the GO aqueous dispersion (10 mg mL −1 ) [37]. The high specific surface area of the GO sheets in the dispersion made it a suitable surfactant to disperse the nanostructured Si NPs.…”

“…Although its capacity is slightly lower than that of some Si/C composites, our design has the following advantages: First of all, compared with the traditional Si/C composite electrode material, our material does not need to add any binder, because its self-supporting structure means that the material does not need to adhere to the current collector during use, which simplifies the preparation process, reduces the manufacturing cost, and provides favorable conditions for future commercialization [36]. Secondly, due to the conductivity of the self-supporting structural material, our material does not need to use a current collector, thereby reducing the volume and weight of the battery and further improving the energy density [37]. Third, compared with the current commercial lithiumion batteries, the composite structure in this paper has high flexibility, can withstand certain bending stress without cracking, and can adapt to different shapes [38].…”
