Summary: By developing an advanced zwitterionic gel polymer electrolyte (GPE) to weaken ion-solvent interactions, the desolvation barriers are lowered and ion transfer kinetics are improved, leading to stable quasi-solid-state sodium ion capacitors. The GPE also forms an inorganic interphase on the anode surface, reducing ion diffusion barriers and improving electrochemical compatibility. The designed GPE enables a hard carbon//activated carbon sodium ion capacitor to achieve 95.3% capacity retention after 9000 cycles, with a high energy density of 140.2 Wh kg(-1).

Summary: In this study, a tris(2,2,2-trifluoroethyl) borate (B(Otfe)3) co-solvent is introduced into the magnesium-aluminum-chloride complex electrolyte to improve the electrolyte solvation sheath and solid electrolyte interphase (SEI) structure. The B(Otfe)3-modified solvation structure increases the concentration of active cation, improving the ionic conductivity and area current density. Meanwhile, the B(Otfe)3-modified solvation ions induce the formation of a more stable SEI, reducing the interfacial transfer impedance. The resulting electrolyte shows excellent electrochemical performance and compatibility with different cathodes.

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: 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: 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.

The CEI, which consists of armored lithium borate and abundant LiF, improves the mechanical stability and Li+ conductivity, leading to excellent cycling performance and capacity retention even at 4.8 V cut-off voltage.

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.

Summary: In this study, l-carnitine (l-CN) is proposed as an efficient additive to stabilize both electrodes and extend the lifespan of aqueous Zn-ion batteries. The simultaneous presence of quaternary ammonium cations, COO- anions, and hydroxyl groups in a trace amount of added l-CN has a significant impact on the behavior of Zn2+ deposition/insertion and water molecule activity. The addition of l-CN leads to ultralong life in the symmetric cell with an 87-fold improvement in cycle life (over 6000 h, 1 mA cm(-2)/1 mA h cm(-2)) for dendrite-free Zn plating/stripping and enables the Zn//V2O5 full cell to achieve 3500 cycles with a high capacity retention.
