“…The newly exposed LM surface was then sputtered with LiF to passivate the Ga-In-Sn sites of LM (these sites may catalyze the decomposition of liquid electrolyte if not isolated or passivated). [58,59] Thanks to the good flowability of LM, the obtained HSE film was continuous, dense, and uniform, which is ideal as a protecting layer for Li-metal anodes. Such a sandwich structure could simultaneously realize high ion transport, electron shut-off, and mechanical strength, which could not be achieved by each component of the sandwich.…”

Integrating solid‐state electrolyte (SSE) into Li‐metal anodes has demonstrated great promise to unleash the high energy density of rechargeable Li‐metal batteries. However, fabricating a highly cyclable SSE/Li‐metal anode remains a major challenge because the densification of the SSE is usually incompatible with the reactive Li metal. Here, a liquid‐metal‐derived hybrid solid electrolyte (HSE) is proposed, and a facile transfer technology to construct an artificial HSE on the Li metal is reported. By tuning the wettability of the transfer substrates, electron‐ and ion‐conductive liquid metal is sandwiched between electron‐insulating and ion‐conductive LiF and oxides to form the HSE. The transfer technology renders the HSE continuous, dense, and uniform. The HSE, having high ion transport, electron shut‐off, and mechanical strength, makes the composite anode deliver excellent cyclability for over 4000 h at 0.5 mA cm−2 and 1 mAh cm−2 in a symmetrical cell. When pairing with LiFePO4 and sulfur cathodes, the HSE‐coated Li metal dramatically enhances the performance of full cells. Therefore, this work demonstrates that tuning the interfacial wetting properties provides an alternate approach to build a robust solid electrolyte, which enables highly efficient Li‐metal anodes.

“…Generally, slight electrolyte decomposition implies the generation of a thin ether-derived SEI and high ICE. Given that the SEI may be influenced by the surface state of electrodes, 214 the morphology, composition and distribution of the ultra-thin SEI on the surface of distinct electrodes have been described in detail. A thin and ionic conductive SEI is also beneficial to enhance the rate capability due to the short diffusion length for sodium ions.…”

“…[ 148 ] The surface adsorption behavior is closely correlated to the microstructure and composition (such as oxygen groups showing specific affinity with some ions) of the active materials, also indicating the electrode‐dependent SEI formation mechanism. [ 227 ] However, these evidences only demonstrate the presence of correlations between microstructure of carbon and the SEI formation. The underlying influence mechanism of these microstructure factors for controlling SEI formation is still unclear.…”

Over the past decades, ground‐breaking techniques and transformative progress have been achieved on exploring alternative battery candidates beyond lithium‐ion batteries, among which sodium‐/potassium‐ion batteries (SIBs/PIBs) are receiving rapidly increased attention. Great efforts have been devoted to developing verified anode materials. Carbon materials take the leading position because of their abundance, low‐cost, environmental friendless, and commercial potential. While it is easy to understand which specific carbon material exhibits outstanding performance, the understanding of electrochemical reaction mechanisms, the structure–performance relation, and the interfacial properties of carbon anodes are rather difficult. It is urgently required to comprehensively summarize and further compare these fundamental issues, but it is still insufficient. This review concentrates on recent progress of carbon materials for SIBs and PIBs, and at the beginning summarizes the fabrication and characterization of different carbon allotropes, then fundamentally compares the ion storage mechanisms and interfacial chemistries. Furthermore, the relationship between the mechanism‐oriented and interface‐correlated performance and material optimization strategies is established. Finally, critical challenges and future developments of carbon anodes for the practical realization of SIBs/PIBs are proposed. This review gives a comprehensive summary and perspective from mechanisms to material design, offering a reliable guidance of carbon materials for SIBs and PIBs.
