“…According to Equation (S1) (Supporting Information), the lithium ion diffusion coefficient is related to the Warburg coefficient, which could be acquired from the fitted line in Figure S10b (Supporting Information). The lithium ion diffusion coefficients of SiO 2 /MXene anode are calculated to be 1.1 × 10 −11 and 1.5 × 10 −11 cm 2 s −1 before cycling and after 200 cycles, respectively, which are higher than those of other representative SiO 2 ‐based anodes reported in literatures . The fast charge transfer at the interface and rapid lithium ion diffusion rate within the anode are attributed to the hybrid of MXene matrix and SiO 2 nanoparticles.…”

To address the non‐negligible volume expansion and the inherent poor electronic conductivity of silica (SiO2) material, microsphere‐like SiO2/MXene hybrid material is designed and successfully synthesized through the combination of the Stöber method and spray drying. The SiO2 nanoparticles are firmly anchored on the laminated MXene by the bonding effect, which boosts the structural stability during the long‐term cycling process. The MXene matrix not only possesses high elasticity to buffer the volume variation of SiO2 nanoparticles, but also promotes the transfer of electrons and lithium ions. Moreover, the microsphere wrapped with ductile MXene film reduces the specific surface area, relieves the side reactions, and enhances the coulombic efficiency. Therefore, superior electrochemical performance including high reversible capacity, outstanding cycle stability, high coulombic efficiency, especially in the first cycle, excellent rate capability as well as high areal capacity are acquired for SiO2/MXene microspheres anode.

“…Thus, the application of the Li‐ion concept through the replacement of the metallic lithium with a stable and non‐reactive anode based on lithium intercalation, [28] conversion, [29] or alloying [30] may actually represent an attractive compromise to safely exploit the multi‐electron conversion process of the Li−S battery [31–36] . In particular, Li‐alloys with Sn [37,38] and Si [39] or their oxides [40–44] exploiting the nanostructured morphology have revealed higher capacity compared to graphite (372 mAh g −1 ), with values ranging from 500 to 1000 mAh g −1 , due to the multiple lithium‐ion exchange per molar unit of metal. Another raising point has been represented by the sustainability of the new energy storage devices, which focused the attention on the necessity of eco‐friendly materials [45,46] .…”

A Stable High‐Capacity Lithium‐Ion Battery Using a Biomass‐Derived Sulfur‐Carbon Cathode and Lithiated Silicon Anode

A full lithium‐ion‐sulfur cell with a remarkable cycle life was achieved by combining an environmentally sustainable biomass‐derived sulfur‐carbon cathode and a pre‐lithiated silicon oxide anode. X‐ray diffraction, Raman spectroscopy, energy dispersive spectroscopy, and thermogravimetry of the cathode evidenced the disordered nature of the carbon matrix in which sulfur was uniformly distributed with a weight content as high as 75 %, while scanning and transmission electron microscopy revealed the micrometric morphology of the composite. The sulfur‐carbon electrode in the lithium half‐cell exhibited a maximum capacity higher than 1200 mAh gS−1, reversible electrochemical process, limited electrode/electrolyte interphase resistance, and a rate capability up to C/2. The material showed a capacity decay of about 40 % with respect to the steady‐state value over 100 cycles, likely due to the reaction with the lithium metal of dissolved polysulfides or impurities including P detected in the carbon precursor. Therefore, the replacement of the lithium metal with a less challenging anode was suggested, and the sulfur‐carbon composite was subsequently investigated in the full lithium‐ion‐sulfur battery employing a Li‐alloying silicon oxide anode. The full‐cell revealed an initial capacity as high as 1200 mAh gS−1, a retention increased to more than 79 % for 100 galvanostatic cycles, and 56 % over 500 cycles. The data reported herein well indicated the reliability of energy storage devices with extended cycle life employing high‐energy, green, and safe electrode materials.
