Summary: Fluorine (F)-heteroatom-functionalized carbon anodes with semi-ionic C-F bonds can significantly increase potassium (K) storage capacity by providing more defect sites for K-ion adsorption. The carbonization temperature plays a crucial role in determining the level of defects. Density functional theory calculations confirm that the presence of semi-ionic C-F bonds enhances K-ion adsorption capability and electronic conductivity, leading to high capacity and rate. Furthermore, the coupling of semi-ionic C-F and pyridinic N bonds further optimizes K adsorption energy and conductivity, resulting in superior capacity and energy density.

Summary: Silicon anodes have been extensively studied as a potential alternative to graphite ones for Li-ion batteries, but their commercial application is limited by poor structural and interfacial stability. Designing robust conductive binder networks is a key strategy to fully exploit the capacity potential of Si-based anodes. This review summarizes existing binders for Si anodes, focusing on three-dimensional and multifunctional polymeric binders with excellent electrical conductivity, flexibility, and adhesion, which are expected to accelerate the practical application of silicon anodes. Suggestions for future development of Si anodic binders are also provided.

Summary: Cu-based cathodes in aqueous batteries have potential advantages but are hindered by serious side reactions caused by the spontaneous formation of Cu2O. In this study, Na2EDTA is introduced to reshape the solvation structure of Cu2+ and modify the electrode/electrolyte interface, reducing the redox potential of Cu2+/Cu2O and inhibiting Cu2O formation. The change in solvation structure also promotes high local concentration and uniform deposition. These findings provide insights for the application of rechargeable Cu-based batteries.

Summary: This study found that the coordination between Li+ and solvents determines the anodic stability of localized high-concentrated electrolytes (LHCEs) on high-voltage cathodes, which can be finely tuned by ambient diluents. Among the possible diluents, 2H,3H-decafluoropentane (HFC) was found to satisfy the principle of weak but sufficient interactions, which enhances Li+ coordination and offers excellent antioxidant chemistry. The study provides guiding principles for improving the cathodic and anodic stability of electrolytes, benefiting the development of LHCEs and inspiring next-generation lithium batteries formulation.

Summary: Currently, critical current density (CCD) is used to evaluate the Li dendrite-suppression capability of solid-state electrolytes (SSEs), but CCD values vary with engineering parameters, leading to a large deviation of CCD values for the same SSE. This study proposes the use of critical interphase overpotential (CIOP) to evaluate the lithium dendrite-suppression capability of SSEs. CIOP is an intrinsic property of the interphase and depends on electronic/ionic conductivity, lithiophobicity, and mechanical strength. By introducing a mix-conductive Li2NH-Mg interlayer between Li6PS5Cl SSE and Li-1.0 wt% La anode, the CIOP is increased from approximately 10 mV (for Li6PS5Cl) to approximately 220 mV. The design of CIOP provides guidance for high-energy and room temperature all-solid-state lithium-metal batteries.

Summary: Research shows that using alternative lithium salts, such as LiBF4, lithium difluoro(oxalato)borate, and LiPF6, in ester/fluoroethylene carbonate electrolytes can enhance low-temperature performance compared to LiPF6 in carbonate-based electrolytes. However, the room-temperature performance of ester-based formulations suffers from capacity fade due to the instability of the solid electrolyte interphase (SEI). Incorporating additives like lithium bis(oxalato)borate, lithium difluorophosphate, and LiTMSP in LiBF4-based ester electrolytes improves room-temperature cycling stability without compromising low-temperature rate performance. The addition of 1% LiTMSP in the LiBF4-based ester electrolyte yields the highest reversible capacity at low temperature and significantly improves room-temperature performance compared to the base ester-based electrolyte, making it comparable to the standard carbonate-based electrolyte.
