Summary: Graphite in potassium-ion batteries shows a faster capacity fade compared to lithium-ion batteries, possibly due to the reactivity of the potassium metal counter electrode or the instability of the solid electrolyte interphase. Previous studies have focused on different electrolyte formulations or charge states of graphite electrodes in potassium half cells. This study compares the surface layers in both charged and discharged states of lithium and potassium half cells, revealing significant differences in SEI composition.

Summary: The physical crosslinking of polymeric binders through coordination chemistry improves the electrochemical performance of silicon-based negative electrodes by stabilizing the electrode and the solid electrolyte interphase (SEI) layer. Scanning electron microscopy coupled with energy dispersive X-ray spectroscopy reveals the homogeneous coordination of carboxylated binder with Zn cations and its layering on the silicon surface. The SEI formed after the first cycle is denser with Zn-coordinated binder and preferentially observed on binder-depleted zones. This results in a lower SEI impedance, a higher first cycle coulombic efficiency, and a 40% improvement of capacity retention after 50 cycles for highly loaded electrodes of over 6 mAh cm(-2).

Summary: The introduction of the unsaturated monomer acrylamide (AM) as an electrolyte additive in water-in-salt electrolyte (WiSE) reduces viscosity and improves ionic conductivity, allowing for in situ electropolymerization into polyacrylamide during charging. This electropolymer forms effective protection layers at both anode and cathode surfaces, leading to high specific capacity, long-term cycling stability, and high rate capability in full cells.

Summary: In this study, the growth mechanism and ionic transport properties of SEIs on Li/Na electrodes were systematically investigated, revealing the liquid/solid composite nature and porosity of SEIs, with SEIs on Na electrodes shown to be more porous than those on Li electrodes. Time-dependent activation energy of SEIs was evaluated using EIS, emphasizing the nonpassivating nature of SEIs on alkali metal batteries.

Summary: This study offers an in situ electrochemistry-driven approach to create a bifunctional interphase by implanting diethylenetriaminepenta(methylene-phosphonic acid) (DTPMP) on the surface of graphite particles. The DTPMP-derived interphase not only enhances the antioxidative stability of electrolytes but also facilitates the desolvation of PF6- anions, leading to the protection of the graphitic structure and enabling fast-charge and ultralong cycling performance in dual-ion batteries (DIBs).

Summary: In this study, we investigate the relationship between the content of solid electrolytes and irreversible capacity in composite electrodes. We analyze the variations of chemical composition and morphology in the solid electrolyte interphase (SEI) layer on the electrodes using electrochemical strain microscopy (ESM) and X-ray photoelectron spectroscopy (XPS). The results show that the solid electrolyte content affects the thickness of the SEI layer and the chemical distributions of Li and F ions, which in turn affect the Coulombic efficiency.

Summary: The novel electrolyte additive p-toluenesulfonyl fluoride (pTSF) has been found to improve the cycling performance of Ni-rich cathode lithium batteries by constructing protective interphase films, reducing interphasial impedance, and preventing metal ion dissolution. This finding is beneficial for the practical application of high energy density lithium batteries.
