Summary: To construct high-energy-density silicon-based Li-ion batteries, it is crucial to optimize and build a robust solid electrolyte interphase (SEI) to overcome the severe side reactions caused by volume changes in silicon (Si) anodes. This study combines electrolyte design and surface modification to create a phenyl trifluoromethanesulfonimide (PTFSI) interfacial layer on the Si surface, with additive functions. The resulting customized PTFSI interfacial layer modulates the solvation/desolvation reaction mechanism at the electrode interface, forming an artificial SEI structure composed of oligomers and inorganic salts. This structure exhibits fast ionic conductivity, reduces electrolyte consumption, and maintains the integrity of the electrode structure, leading to significantly improved rate capability and cycling performance of the optimized Si@PTFSI anode.

Summary: By forming an artificial solid electrolyte interphase (ASEI) on the surface of ferrosilicon/carbon (FeSi/C) anode through a designed nucleophilic reaction of polysulfides with vinylene carbonate (VC) and fluoroethylene carbonate (FEC) molecules, it effectively prevents electrolyte infiltration and decomposition while enabling Li+ transport, thus stabilizing the FeSi/C anode interface. The ASEI-modified FeSi/C anode exhibits a large reversible capacity, excellent cycling stability, and greatly elevated cycling coulombic efficiency, potentially serving as a high-capacity anode of LIBs.

Summary: A new protocol was developed to compare battery life by using a constant potential and monitoring the current needed to maintain the potential. The results showed that EC and LiPF6 led to higher current and poorer passivation, while EMC had no effect on passivation. The mole fractions of the components also affected the composition of the solid-electrolyte interphase (SEI). Higher LiPF6 content resulted in increased LiF and current, but did not enhance passivation on the silicon surface. Comparing different compounds, it was found that EC did not generate a passivating SEI, while other compounds showed varying levels of passivation.

Summary: A key challenge in lithium-ion batteries is the instability of electrolytes against anode materials, with the solid-electrolyte interphase (SEI) providing stability at the cost of capacity consumption. Artificial SEIs offer more flexibility to tune properties such as chemical composition and impedance, but must ensure sufficient transport properties for Li-ions and stability.

Summary: Mechanical instabilities of the solid electrolyte interphase (SEI) layer can lead to battery degradation. The large deformations imposed by rubbery-based electrodes during lithiation and delithiation can cause interphase mechanical instabilities. By considering the theory of nonlinear elasticity and conducting simulations, the critical electrode radius for the instability to occur can be determined. Incorporating the heterogeneity hypothesis of a bilayer SEI improves the model and warns of the errors that can occur by neglecting the microstructure of the shell layer.

Summary: This study evaluates the effect of covalently attached molecular coating hydrophobicity on the surface of the silicon nanoparticle active anode material for Li-ion batteries, finding that hydrophilic PEO coatings can electrochemically isolate Si NPs at a thickness of around 2.5 nm, with little effect on minimizing electrochemical side reactions.

Summary: SERS is ideal for providing bacterial-specific molecular fingerprints, but generating reproducible spectra in complex structures like bacteria remains challenging. The study shows that the environment of bacteria affects the origin of SERS spectra, with densely packed bacteria exhibiting characteristic signatures related to secretion or cell structures, and isolated bacteria showing spectral variabilities. The variabilities do not prevent discrimination of different E. coli strains based on SERS signatures.

Summary: LiNixCoyMn1-x-yO2 (NCM) is a critical cathode material for lithium-ion batteries in electric vehicles. The aging of cathode/electrolyte interfaces leads to capacity degradation and long-term cycle instability. A novel neural network model called ACGNet is developed to predict electrochemical stability windows of crystals, allowing for high-throughput screening of coating materials. LiPO3 is identified as a promising coating material with high oxidation voltage and low cost, which significantly improves the cycle stability of NCM batteries. This study demonstrates the accuracy and potential of machine learning in battery materials.

Summary: In this study, a bifunctional electrode host design consisting of carbon nanofibers implanted ordered porous Co-decorated Al2O3 supported on carbon nanotube film (CNTF) was proposed to address the shuttling effect of lithium polysulfides (LiPSs) and dendrite formation of metal lithium anode in lithium-sulfur (Li-S) batteries. The electrode exhibited excellent conductivity, efficient confinement of LiPSs, and catalytic conversion performance, resulting in high initial capacity and good capacity retention during cycling. As an anode, the electrode showed excellent Li+ diffusion performance and uniform lithium growth behavior, achieving a dendrite-free lithium electrode. The flexible pack cell assembled from these electrodes delivered a specific capacity of 972 mAh g(-1) with good capacity retention.
