Carbon in lithium-ion and post-lithium-ion batteries: Recent features

Effect of Post-synthesis Processing on the Electrochemical Performance of Y2W3O12

“…In the case of SANS, the scattering originates from nuclear scattering lengths. The intensity I ( q ) is directly proportional to ΔSLD at an interface, wherein ΔSLD is the difference in the SLD values of different interface components …”

“…The biggest challenge in facilitating a complete migration to these renewable resources is their inherently intermittent nature which in turn requires advanced energy storage systems. Lithium-ion batteries (LIBs), first marketed by Sony in 1991, feature excellent properties such as good rechargeability, light weight, good power density, and high gravimetric and volumetric energy densities. , Since their inception, graphite has been the material of choice for the anode in LIBs. However, it has several limitations such as limited rate capability (especially during the lithiation process), low initial Coulombic efficiency (ICE), high processing costs due to the use of harmful chemicals typically required for its production, and a limited theoretical capacity of 372 mAh/g .…”

Neutron and muon characterisation techniques for battery materials

“…lower than that of Li + motion in LiCoO 2 133 and around half that of Na + motion in Na 0.7 CoO 2 126 . A low activation energy of 120 (13) meV also highlighted the fast ion transport near the second muon site. In this instance, an accurate prediction of the muon site would prove beneficial for a greater understanding of diffusion pathways and to distinguish between the two experimentally determined muon environments.…”

“…However, Li-ion intercalation into the graphite layers has a low diffusion rate associated with it, making the anode material non-ideal for high power applications. 13 Na-ions cannot intercalate into graphite (without the help of co-intercalation solvents), so hard carbons are typically used. 14,15 Hard carbon is a turbostratically disordered analogue of graphite, containing curvature within the layers (Figure 3, third left to right).…”

Impact of LiBOB additive on cycle-performance degradation of lithium mono-chelated borate electrolytes: minimize the crosstalk-derived deterioration

“…To form a protective layer, both ex situ and in situ methods that use graphite with a modified surface before cell assembly has been proposed. 14 For example, oxidation treatment, 15 coating with sodium maleate solution, 16 and the polymerization of acrylate have been applied to the graphite surface to form a film ex situ , 17 successfully suppressing electrolyte decomposition during charging and reducing the irreversible capacity. However, there are issues such as an increase in the number of processes required to assemble the cell compared to the case where an untreated active material is used.…”
