Summary: Lithium-sulfur (Li-S) batteries are highly promising high-energy-density secondary batteries due to their ultrahigh energy density and low cost. A dual-functional electrolyte additive, lithium selenide (Li2Se), is proposed to address the challenges faced by Li-SPAN batteries, including sluggish sulfur kinetics and uncontrollable Li deposition. Li2Se improves kinetics by attacking polysulfides and forms a stable selenide-containing organic-inorganic hybrid solid electrolyte interphase (SEI) to enhance Li deposition. The Li2Se-assisted Li-SPAN battery exhibits high discharge capacities, enhanced rate performance, and outstanding cycling stability.

Summary: In this work, localized high concentration electrolytes (LHCEs) based on tetramethylene sulfone (TMS) were designed. TMS-based LHCEs can achieve excellent compatibility with high energy density lithium-ion batteries (LIBs) when combined with a proper additive. The unique solvation structure of LHCEs facilitates the formation of highly effective solid electrolyte interphase (SEI) and suppresses the degradation of positive electrode materials in LIBs. The superior interphasial properties of LHCEs are the key to realizing the long lifespan of high energy density LIBs.

Summary: Electrolyte engineering plays a crucial role in the development of high-performance lithium metal batteries. In this study, two cosolvents with significantly different reduction potentials, methyl bis(fluorosulfonyl)imide (MFSI) and 3,3,4,4-tetrafluorotetrahydrofuran (TFF), were synthesized and added to LiFSI-DME electrolytes. The LiFSI/TFF-DME electrolyte showed an average Li Coulombic efficiency (CE) of 99.41% over 200 cycles, while the average Li CEs for the MFSI-based electrolyte were only 98.62%. Furthermore, the TFF-based electrolytes exhibited more reversible performance than the state-of-the-art fluorinated 1,4-dimethoxylbutane electrolyte in various battery configurations.

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: 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.

Summary: Long-term mitigation of dendrite growth is achieved by an advanced alloy surface with optimized interfacial kinetics regulated by the electrolyte solution. The reinforced displacement reaction driven by the potential gap between Ag+ and Zn promotes fast formation of a dendrite-free Li deposition with high diffusion rates in both lateral and longitudinal directions. The synergy between the alloy surface and the electrolyte solvation structure is critical for retaining the functionality of the alloy surface and improving the cycling performances of the Li-metal batteries.

Summary: Solid-state lithium-air batteries (SSLABs) have attracted significant research interest as promising energy storage systems with ultra-high theoretical energy density. However, their practical capacity and cyclic performance have not yet met application requirements due to their relatively short development history. This review provides a comprehensive overview of recent scientific progress and challenges in SSLABs, focusing on solid electrolytes, air cathodes, and interface issues. Strategies such as electrolyte modification, composite cathodes, interface engineering, and the addition of catalysts have been reviewed and discussed as effective approaches to address issues related to low ionic conductivity, high interfacial impedance, sluggish kinetics, and poor cycling stability. The prospects of SSLABs and their implications for the development of solid-state lithium-air batteries and other metal-air batteries are also discussed.
