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: Electrolyte engineering-controlled interfacial chemistries are crucial for stable lithium-metal batteries. In this study, the introduction of the active difluoroethylene carbonate (DFEC) co-solvent leads to the formation of a local high concentrated electrolyte (LHCE), which enhances interfacial chemistries. The DFEC serves as both additive and diluent, reinforcing the anion-solvation-derived interfacial layers and improving the cycle stability of the Li||LiCoO2 full cell and pouch cells.

Summary: Ni-rich layered transition metal oxides are the best cathode materials for fast charging of Li-ion batteries. Strategies to improve the rate capability of Li-ion cells include breaking down the spherical secondary structure of NCM811 and reconstructing the native surface layer to reduce interfacial resistance. Adding an appropriate amount of H2C2O4 into the slurry is shown to dramatically reduce interfacial resistance between the cathode and electrolyte.

Summary: In this study, impedance spectroscopy was used to investigate the effect of concentration on the lithium-ion transference number and compare two electrolytes, LiFSI in SL and LiTFSI in G4. The results showed that the transference number of Li+ in the SL system was significantly higher and increased with concentration, while the G4 system showed the opposite trend. This difference can be attributed to the formation of a liquid structure in the SL system, which facilitates cation-hopping diffusion, while the G4 system is dominated by solvation cages.

Summary: The effects of fluoroethylene carbonate (FEC) electrolyte additive on the reactivity of charged sodium ion electrode/electrolyte at elevated temperatures were investigated. It was found that the addition of FEC can extend the cell lifetime without significantly affecting the reactivity of sodium-ion electrode. However, FEC has an obvious effect on the reactivity between hard carbon and electrolytes.

Summary: Despite extensive research efforts, fundamental scientific questions still obscure the commercial prospects of aqueous rechargeable zinc metal batteries (RZMBs), especially regarding the properties and behaviors of the electrode-electrolyte interphase. In this review, a comprehensive overview is provided on the formation mechanisms and characteristics of the solid electrolyte interphase (SEI) and cathode electrolyte interphase (CEI) in aqueous RZMBs. State-of-the-art techniques for characterizing the SEI/CEI are summarized to reveal the correlation between the interphases' functionalities and electrochemical performances. Future research directions exploring the evolution of aqueous SEI/CEI with pH and temperature, as well as studying SEI/CEI for high-energy-density and long-lifetime RZMBs, are proposed.
