Summary: Silicon thin-film is a promising anode material for lithium-ion batteries due to its high cycle stability and initial coulombic efficiency. However, the low areal capacity and tendency for layer misalignment and separation limit its practicality. By studying silicon films with a thickness of 700 nm, researchers found that the volume of silicon does not recover after delithiation, causing significant swelling. The non-uniform film substrate helps to maintain a relatively stable structure. Despite these challenges, the specific capacity retention of the silicon film electrode after 100 cycles is 64.35%.

Summary: Silicon nitride-based electrodes (SiNx) have been proposed as candidates for high-capacity transparent anode electrodes, but their low electrical conductivity limits their application in thin film batteries. To overcome this, we introduced uniformly dispersed Ag nanoparticles in SiNx thin film to enhance electrochemical properties without affecting transmittance. The addition of Ag increased the capacity of the thin-film battery and allowed for higher C rates, while maintaining optical transmittance over 60% in the visible range.

Summary: In this study, sodium diphenyl ketone (Na-DK) was used to presodiate the hard carbon (HC) anode for sodium-ion batteries, improving its initial Coulombic efficiency and stability. Na-DK achieved dual-function presodiation by compensating the irreversible sodium uptake at oxygen-containing functional groups and reacting with carbon defects in HC. The resulting sodium induced a robust sodium fluoride (NaF)-rich solid electrolyte interphase (SEI) on HC, promoting interfacial reaction kinetics and stable sodium insertion and extraction. This work demonstrated high capacity retention of approximately 100% and 82.4% after 6800 cycles for presodiated HC (pHC) and full cells with Na3V2(PO4)3 cathodes, respectively. It provides valuable insights into chemical presodiation and offers a new strategy for highly stable sodium-ion batteries.

Summary: This study attempts a solvation-regulated strategy in tetraethylene glycol dimethyl ether (G4) based electrolyte to achieve stable lithium anodes in Li-O-2 batteries. By incorporating trifluoroacetate anions (TFA(-)) with strong Li+ affinity into the lithium bis(fluorosulfonyl)imide (LiTFSI)/G4 electrolyte, the Li+-G4 interaction is attenuated and anion-dominant solvates are formed. The bisalt electrolyte with 0.5 M LiTFA and 0.5 M LiTFSI mitigates G4 decomposition and induces an inorganic-rich solid electrolyte interphase (SEI), leading to improved Li+ diffusion and extended lifespan in Li-O-2 batteries.

Summary: This study demonstrates that regulating the chelating power and coordination structure can significantly enhance the high-voltage stability of ether-based electrolytes and the lifespan of lithium metal batteries. The use of 1,3-dimethoxypropane (DMP) and 1,3-diethoxypropane (DEP) as solvents in the electrolytes instead of the traditional 1,2-dimethoxyethane (DME) results in the formation of weak Li solvates, contributing to improved reversibility and high-voltage stability in lithium metal batteries. The fabricated high-voltage Li||LiNi0.8Co0.1Mn0.1O2 lithium metal batteries using 2.30 M Lithiumbisfluorosulfonimide (LiFSI)/DMP electrolyte show excellent capacity retention over 90% after 184 cycles, even under lean electrolyte and low anode to cathode ratio conditions.

Summary: In this study, the facet selectivity of commonly used Cu current collector for Li metal electrodeposition was investigated using density functional theory (DFT) and ab initio molecular dynamics (AIMD) simulations. Nine Li-Cu interfaces composed of low-index crystal facets were evaluated for stability based on descriptors such as adsorption energy, lattice mismatch, formation energy, and diffusion constant of lithium atoms. The results indicate that Cu(100) and Cu(110) surfaces are preferential for the growth of Li(100) in Li crystal facets (100), (111), and (100), while Cu(111) surface prefers forming Li(110). It is suggested that Cu(110) may be superior to Cu(100) and Cu(111) for Li deposition, providing a useful guideline for improving the efficiency of Li deposition by controlling the morphology of the current collector.
