However, the cycle life of Li metal batteries with liquid electrolytes is severely hindered by the high reactivity and non-uniform plating/stripping behaviors of Li metal anodes. The plating/stripping behaviors of Li metal anodes are mainly dictated by the transport mechanism of Li ions in solid electrolyte interphase (SEI), a nanoscale passivation film between the anode and electrolytes. SEI is composed of various inorganic and organic components and has a diversiform structure, which complicates the transport behaviors of Li ions in it and differentiates the Li-ion transport mechanism in SEI from that in common liquid and solid electrolytes. Therefore, understanding the transport mechanism of Li ions in SEI is imperative for rationally regulating SEI components and structure and enabling uniform Li plating/stripping behaviors. In this review, the recent progress in understanding the Li-ion transport mechanism in SEI in Li metal batteries with liquid electrolytes is summarized, including the detailed transport mechanisms of Li ions in SEI, and the methods to investigate and regulate the Li-ion transport mechanism in SEI.

Transforming growth factor-β (TGF-β) and hypoxia are key processes in the development of solid tumors, including the formation of neo-vasculature, dense extracellular matrix (ECM), and immunosuppression. TGF-β inhibition and hypoxia alleviation may be promising approaches to enhance activity of CAR-T cells in solid tumors.

BM/LP<sub>siTGF-β</sub> NPs efficiently eliminates ECM by down-regulation of TGF-β. Additionally, BM/LP<sub>siTGF-β</sub> NPs also produces abundant O<sub>2</sub> and down-regulates HIF-α, leading to normalized vasculature and improved tumor immunosuppression. More importantly, the ECM degradation induced by BM/LP<sub>siTGF-β</sub> NPs forms a self-reinforcing loop, further promoting greater tumor penetration of BM/LP<sub>siTGF-β</sub> NPs and CAR-T cells.
