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: In this study, the interface stability of sodium ion batteries (SIBs) is improved by suppressing the continuous growth of the solid-electrolyte interphase (SEI) from the perspective of mitigating electron leakage. Two types of SEI layers with different growth behaviors were created through the additive strategy, and their physicochemical features and electronic properties were extensively investigated. Experimental and calculational analyses demonstrated that the suppressed growth SEI layer exhibits both low electron driving force and high electron insulation ability, mitigating electron leakage and enhancing electrochemical performance.

Summary: The growth mode of solid electrolyte interphase (SEI) on carbonaceous anodes in Li-ion batteries is studied using classical nucleation theories and in situ atomic force microscopy imaging. The formation of inorganic SEI follows a mixed 2D/3D growth model that is highly dependent on overpotential, while organic SEI strictly follows a 2D instantaneous nucleation and growth model regardless of overpotential. Insights obtained from these studies have the potential to tailor desired interphases at the nanoscale for future electrochemical devices.

Summary: A 10-nm polydopamine coating on the residue-removed garnet surface is shown to stabilize the modified garnet filler and prevent the generation of alkaline residues, allowing PVDF to remain intact. Metal-nitrogen bonding between the La atoms of garnet and the amino groups of polydopamine promotes stronger adsorption of Li ions, enabling an efficient ion-percolation network for Li-ion conduction through the garnet-polydopamine interface. The composite electrolyte demonstrates an effective room-temperature Li+ conductivity of 1.52 x 10(-4) S cm(-1) and a high cutoff voltage of up to 4.7 V versus Li+/Li to support stable operation of all-solid-state Li-LiCoO2 batteries.
