Summary: The electrolyte additive, succinic anhydride (SA), serves as a synergistic filming additive with fluoroethylene carbonate (FEC) to significantly improve the lifespan and stability of dual-additive Na/Na0.6Li0.15Ni0.15Mn0.55Cu0.15O2 (NLNMC) batteries. The addition of SA leads to a more uniform and stable interphase layer on the cycled NLNMC material, containing more oxygen-rich organic species and less NaF. Additionally, SA also influences the interphase layer in the sodium anode part, as shown by electrochemical impedance spectroscopy and energy dispersive spectrometer results.

Summary: Research has shown that the use of all-fluorinated electrolytes can greatly enhance the reversibility and cyclability of room-temperature sodium-sulfur batteries. This is achieved by the formation of a cathode electrolyte interphase rich in NaF and Na3N, which eliminates the shuttle of polysulfides. Additionally, the all-fluorinated electrolyte stabilizes the Na anode through a tailored solvation structure.

Summary: In this study, two isomers were mixed in different proportions and used as the organic anode material for sodium-ion batteries (SIBs). The mixed material showed distinct morphology and electrochemical properties compared to the single-component materials. The mixed material exhibited higher initial Coulombic Efficiency (ICE) and better capacity retention after cycles due to its superior morphology, which increased the contact area with the electrolyte and ensured close contact with the conductive carbon. This work provides new insights into the development of organic electrode materials for future SIBs.

Summary: Semiconductors have been optimized in thickness to enhance their surface-enhanced Raman scattering (SERS) activity in noble metal/semiconductor SERS substrates. However, the influence of the strong surface plasmon resonance (SPR) effect from the noble metals has made it difficult to fully understand the charge transfer (CT) resonance mechanism caused by the change of the semiconductor thickness. This study systematically evaluates the CT mechanism by developing systems with precisely controlled TiO2 thicknesses, and demonstrates that a TiO2 thickness of 40 nm exhibits the highest SERS activity.

Summary: The pursuit of high gravimetric specific energy often overlooks the importance of volumetric energy density in batteries. This paper proposes an anode-free Mg2Mo6S8-MgS/Cu battery, which utilizes MgS as a premagnesiation additive to replenish Mg loss through electrolyte corrosion. Both Mg2Mo6S8 and MgS act as active materials to provide high capacities. The anode-free Mg2Mo6S8-MgS/Cu battery delivers a high reversible capacity of 190 mAh g(-1) with a capacity retention of 92% after 100 cycles, resulting in a competitive energy density of 420 Wh L-1. This study highlights the great potential of Mg batteries in achieving high volumetric energy densities.
