“…Additionally, the flammable, corrosive, and thermally unstable nature of liquid electrolytes poses prominent safety issues under high energy density conditions . The use of solid-state electrolytes in place of liquid electrolytes in solid-state batteries can fundamentally address these safety concerns and hold promise for achieving higher energy densities matching high-capacity cathodes and lithium metal anodes. − For this reason, solid-state lithium-Ion batteries have garnered increasing attention and research. , However, solid-state batteries currently face significant challenges with high interfacial impedance, − which represents a crucial barrier to the commercialization of solid-state batteries . This is attributed to the solid–solid contact between the solid electrolyte (SE) and the cathode, leading to increased interfacial impedance due to contact losses from morphological changes over the life.…”

The use of solid electrolytes (SE) in solid-state batteries holds the promise of achieving higher energy densities and enhancing safety. However, current solid-state batteries face significant interface impedance issues, mainly dealing with the effect of the evolution of the solid−solid interface on ion transport. Semi-solid-state batteries (SSB), containing a small amount of liquid electrolyte, serve as appropriate transitional products in the development process of solid-state batteries. More importantly, the clarity of the relevant interface dynamics can provide theoretical guidance for the subsequent all-solid-state batteries. Therefore, this paper investigates SSB through Electrochemical Impedance Spectroscopy (EIS), primarily employing a combination of theoretical modeling, simulation predictions, and experimental analyses to elucidate the complex electrochemical processes within these batteries. Based on detailed exploration of the complex electrochemical processes within SSB, we have discovered additional electrochemical processes beyond Li + penetration through the solid-electrolyte interphase (SEI) film and charge transfer. We attribute the additional electrochemical reaction processes to the resistance present at the SE/SEI interface of SSB on account of numerical analysis and interface characterization. Furthermore, this interface resistance exhibits a trend of initial decrease followed by continuous increase, elucidating the attribution and numerical variations of various impedance components within the EIS. The application of EIS techniques to analyze ion transport processes in SSB serves as a suitable transition toward achieving all-solid-state batteries as well as provides guidance for subsequent interface optimization of solid-state batteries and propels their transition from laboratory experimentation to commercialization.

Lithium‐sulfur (Li‐S) batteries are considered as a most promising rechargeable lithium metal batteries because of their high energy density and low cost. However, the Li‐S batteries mainly suffer the capacity decay issue caused by the shutting effect of lithium polysulfides and the safety issues arising from the Li dendrites formation. This review outlines the current issues of Li‐S batteries. Furthermore, we comprehensively summarized the challenges encountered by Li anode in Li‐S batteries, such as the heterogeneous deposition of the Li anode, the unstable solid electrolyte interface (SEI) layer, and volume expansion. Moreover, research progresses in the stabilization strategies of Li anodes (physical approaches, optimization of electrolyte, surface protection layer, and design of current collector) is discussed in detail. Lastly, the remaining challenges and future research directions of Li metal anode stabilization in Li‐S batteries are also present.

In practical operating conditions, the lithium deposition behavior is often influenced by multiple coupled factors and there is also a lack of comprehensive and long‐term validation for dendrite suppression strategies. Our group previously proposed an intermittent lithiophilic model for high‐performance three‐dimensional (3D) composite lithium metal anode (LMA), however, the electrodeposition behavior was not discussed. To verify this model, this paper presents a modified 3D carbon cloth (CC) backbone by incorporating NiFe2O4/Fe2O3 (NFFO) nanoparticles derived from bimetallic NiFe‐MOFs. Enhanced Li adsorption capacity and lithiophilic modulation were achieved by bimetallic MOFs‐derivatives which prompted faster and more homogeneous Li deposition. The intermittent model was further verified in conjunction with the density functional theory (DFT) calculations and electrodeposition behaviors. As a result, the obtained Li‐CC@NFFO||Li‐CC@NFFO symmetric batteries exhibit prolonged lifespan and low hysteresis voltage even under ultra‐high current and capacity conditions (5 mA cm‐2, 10 mAh cm‐2), what’s more, the full battery coupled with a high mass loading (9 mg cm‐2) of LiFePO4 cathode can be cycled at a high rate of 5C, the capacity retention is up to 95.2% before 700 cycles. This work is of great significance to understand the evolution of lithium dendrites on the 3D intermittent lithiophilic frameworks.
