“…[48] Furthermore, the particle size change of NSM electrode is smaller than that of SnO 2 electrode, implying that the porous structure and multilevel buffering play an important role to reversible Li + storage process. [49] To further interpret the electrochemical evolution of host material during the initial cycle, the in-situ XRD patterns are collected along with the charge-discharge curve at a current density of 100 mA g −1 . As illustrated in Figure 6c, the strong characteristic peak located at 45.8°are attributed to Be (110) of metal boron used as the window of the in-situ sample pool.…”

Heterostructures with interfacial effects have exhibited great potential for improving the electrochemical kinetics of electrode materials. However, the application of heterostructures is hampered by complicated synthesis parameters and numerous single components. Herein, a multiple‐templating synthesis strategy is proposed to improve the interfacial effect of heterojunction composites, mitigate volume variation upon lithiation/de‐lithiation, and increase interfacial compatibility with poly‐oxyethylene‐based (PEO‐based) electrolytes. Benefiting from the structural and compositional superiorities, the novel NiS/SnO2/MOF (NSM) electrode achieves superior electrochemical performance with exceptional specific capacity, outstanding rate capability and ultralong cyclability. As a result of the compatibility between organic components and the porous properties of metal organic frameworks (MOFs), the NSM electrode exhibits greater interfacial compatibility with PEO‐based solid‐state electrolytes. This work not only describes a meticulous protocol for heterostructured high‐performance electrode materials, but also provides a new insight to enhance the connectivity between the interfaces of solid‐state batteries.

“…In situ synchrotron radiation (SR) techniques, such as X-ray absorption spectroscopy [ 22 ], X-ray reflectivity [ 23 ], X-ray diffraction [ 24 ], and small angle X-ray scattering (SAXS) [ 25 , 26 ], have been used to study real-time structural changes in electrode materials of lithium-ion batteries. In situ electrochemical-SR combined techniques can be used to obtain information on structural changes, such as crystal transformation, changes in oxidation state, solid electrolyte interface (SEI) characterization, and lithium dendrite growth mechanisms during lithium-ion embedding/de-embedding [ 23 , 24 , 25 ]. For instance, the SR XRD technique investigates that the CuO/GO anode material displays a noticeable shift of the CuO(-511) Bragg peak to a higher angle due to Li + doping in the CuO lattice during the first cycle.…”

As a candidate anode material for Li-ion batteries, Bi-based materials have attracted extensive attention from researchers due to their high specific capacity, environmental friendliness, and simple synthesis methods. However, Bi-based anode materials are prone to causing large volume changes during charging and discharging processes, and the effect of these changes on lithium storage performance is still unclear. This work introduces that Bi/C nanocomposites are prepared by the Bi-based MOF precursor calcination method, and that the Bi/C nanocomposite maintains a high specific capacity (931.6 mAh g−1) with good multiplicative performance after 100 cycles at a current density of 100 mA g−1. The structural evolution of Bi/C anode material during the first cycle of charging and discharging is investigated using in situ synchrotron radiation SAXS. The SAXS results indicate that the multistage scatterers of Bi/C composite, used as an anode material during the first lithiation, can be classified into mesopores, interspaces, and Bi nanoparticles. The different nanostructure evolutions of three types of Bi nanoparticles were observed. It is believed that this result will help to further understand the complex reaction mechanism of Bi-based anode materials in Li-ion batteries.

This study has investigated the effect of carbon coating on the electrochemical performance of SnO2 Nanowires (NWs) as an electrode along with a bis (trifluoromethane) sulfonimide lithium (LiTFSI)-based electrolyte in a lithium-ion battery (LIB). The vapor-liquid-solid (VLS) approach has been used to grow SnO2 NWs on the stainless steel mesh current collector. The obtained results have demonstrated that the utilization of the LiTFSI-based electrolyte improved the battery performance with the SnO2 NWs electrode over the LiPF6-based electrolyte. This may be due to the formation of a stable and thin solid electrolyte interphase (SEI) layer. Since bare SnO2 NWs exhibit inferior cycling stability due to their high volumetric expansion and poor conductivity, incorporating carbon coating could improve performance. Although the initial discharge specific capacity obtained for the carbon-coated SnO2 NWs (SnO2 NWs@C) electrode (1328.4 mAh g-1) was in the order of the first discharge capacity for the SnO2 NWs, the SnO2 NWs@C electrode possessed capacity retention with 6 times improvement as compared to the pristine SnO2 NWs after 120 cycles. The coulombic efficiency of 99% has been achieved for the SnO2 NWs@C electrode over 120 cycles. Field Emission Scanning Electron Microscopy (FESEM) images revealed that the carbon coating could keep the overall structure of the electrode upon cycling. It has been evidenced that the SnO2 NWs@C electrode with LiTFSI-based electrolyte has an excellent potential to implement in high-performance LIBs.
