Summary: Realizing uniform Li+ flow is crucial for achieving even Li deposition in lithium metal batteries (LMBs). In this study, a dynamic ion sieve concept is proposed, which involves designing a buffer layer near the Li anode surface to regulate Li+ spatial arrangement by introducing TMPB into the carbonate electrolyte. The buffer layer induced by TMP+ allows solvated Li+ sufficient time to redistribute and accumulate on the Li anode surface, resulting in a uniform and concentrated Li+ flow. Additionally, TFSI- participates in the formation of an inorganic-rich solid electrolyte interphase (SEI) with Li3N, enhancing the Li+ conductivity of the SEI. As a result, the stable and uniform Li deposition achieved excellent cycling performance in Li||Li symmetric cells for up to 1000 hours at 0.5 mA cm(-2). Furthermore, the Li||NCM622 full cell exhibited excellent cycling stability with a high-capacity retention rate of 66.7% after 300 cycles.

Summary: Tailoring the inorganic components of the CEI and SEI in lithium metal batteries is crucial for improving their cycling performance. By using PFBNBS as an electrolyte additive guided by functional groups, the species and inorganic content of the CEI/SEI are enriched with a gradient distribution. Furthermore, the catalytic effect of the NCM622 cathode on the decomposition of PFBNBS is proposed. This tailored electrolyte enables the formation of an inorganic-rich CEI on NCM622 and an increased inorganic content in the SEI, leading to superior electrochemical performance and inhibiting electrolyte decomposition.

Summary: NaF-rich electrode-electrolyte interphases play a crucial role in the cycling stability of sodium metal batteries. The addition of perfluorobenzene (PFB) promotes the formation of NaF-rich solid electrolyte interphases (SEI). PFB can extract a part of EC with the lowest solvation energy, allowing more PF6- to participate in the solvation layer and form an anion-aggregated solvation sheath, thus facilitating the decomposition of PF6- to produce NaF. The Na||Na symmetric cells with this electrolyte exhibit superior cycling performance and the Na||Na3V2(PO4)(2)O2F batteries achieve high capacity retention after 500 cycles.

Summary: Lithium metal batteries (LMBs) with high-voltage nickel-rich cathode and Li metal anode have the potential for high capacity and power density, but electrolytes that can withstand oxidation on the cathode at high cut-off voltage are urgently needed.

Summary: A strategy for constructing a robust interphase layer using an unsaturated imidazole-based ionic liquid additive ([Vmim1O2][TFSI]) is proposed to stabilize high-voltage Li-rich Li-metal batteries. The ionic liquid with a vinyl group preferentially adsorbs on both the cathode and anode surface, suppressing transition metal ion dissolution and mitigating structural degradation of the electrode. Experimental results show that the Li-metal anode with [Vmim1O2][TFSI]-based electrolyte exhibits stable Li plating/stripping over 750 h, and the full cells with Li1.170Ni0.265Co0.047Mn0.517O2 cathode demonstrate long-term cyclicity with a capacity retention of 87.89% after 350 cycles at 4.8 V.

Summary: Increasing the cut-off voltage of cathodes improves the energy density of Li||LiCoO2 batteries, but also leads to rapid battery degradation due to oxidation and deterioration. However, by using bis-(benzenesulfonyl)imide (BBSI) as an additive, a uniform and highly Li+ conductive cathode electrolyte interphase (CEI) is constructed, which stabilizes the batteries at 4.6 cut-off voltage and exhibits superior cycling and high-rate performance. The CEI, consisting of LiF and conductive Li+ moieties, improves Li+ migration, alleviates cathode degradation, and reduces other secondary degradation factors. Li||LiCoO2 batteries with 1% BBSI-containing electrolyte sustain 81.30% of initial capacity after 300 cycles at 0.5C, and 88.27% of initial capacity even after 500 cycles at 2C/3C.
