“…However, notorious dendrite propagation gives rise to large volume expansion, low reversibility and potential safety hazards [ 51 ]. In polymer electrolytes, heterogeneous interface, limited ion transport and low mechanical strength are the primary reasons driving dendrite growth [ 52 ]. Firstly, solid electrolyte interface (SEI) realizes the dynamic passivation of the electrode, which expands the electrochemical window of LMBs to a certain extent [ 53 ].…”

Highlights The current issues and recent advances in polymer/inorganic composite electrolytes are reviewed. The molecular interaction between different components in the composite environment is highlighted for designing high-performance polymer/inorganic composite electrolytes. Inorganic filler properties that affect polymer/inorganic composite electrolyte performance are pointed out. Future research directions for polymer/inorganic composite electrolytes compatible with high-voltage lithium metal batteries are outlined. Abstract Solid-state electrolytes (SSEs) are widely considered the essential components for upcoming rechargeable lithium-ion batteries owing to the potential for great safety and energy density. Among them, polymer solid-state electrolytes (PSEs) are competitive candidates for replacing commercial liquid electrolytes due to their flexibility, shape versatility and easy machinability. Despite the rapid development of PSEs, their practical application still faces obstacles including poor ionic conductivity, narrow electrochemical stable window and inferior mechanical strength. Polymer/inorganic composite electrolytes (PIEs) formed by adding ceramic fillers in PSEs merge the benefits of PSEs and inorganic solid-state electrolytes (ISEs), exhibiting appreciable comprehensive properties due to the abundant interfaces with unique characteristics. Some PIEs are highly compatible with high-voltage cathode and lithium metal anode, which offer desirable access to obtaining lithium metal batteries with high energy density. This review elucidates the current issues and recent advances in PIEs. The performance of PIEs was remarkably influenced by the characteristics of the fillers including type, content, morphology, arrangement and surface groups. We focus on the molecular interaction between different components in the composite environment for designing high-performance PIEs. Finally, the obstacles and opportunities for creating high-performance PIEs are outlined. This review aims to provide some theoretical guidance and direction for the development of PIEs.

“…In recent years, lithium metal batteries (LMBs) with a much higher theoretical capacity have become the object of favor for the next-generation energy storage devices . Unfortunately, direct use of lithium metal anode in LMBs with the traditional liquid electrolytes usually suffers from the drawbacks including the chemical instability and the ramified growth of lithium dendrites, which can easily result in poor cycling stability, short circuit, and even severe safety hazards, greatly limiting the practical use of LMBs. − To address these problems, many strategies have been employed in the past years, such as optimizing the liquid electrolytes by addition of special additives, − constructing artificial protective layers, − engineering three-dimensional host structures for lithium metal anode, , and using solid-state electrolytes (SSEs). − Among these strategies, using SSEs to replace the traditional organic liquid electrolytes has attracted considerable attention for the next-generation solid-state LMBs because of their much more superior chemical and electrochemical stability, higher mechanical strength to suppress the growth of lithium dendrites, and thereby better safety. − …”

Construction of polymer-based electrolytes with excellent mechanical properties and high ionic conductivity is highly desirable for solid-state lithium−metal batteries. Herein, a scalable strategy is suggested to achieve the high strength and high performance polymer-based solid-state electrolyte via filling polyethylene oxide (PEO)/Li-salt (LiTFSI) electrolyte into an interconnected metal−organic framework (MOF) network based on the typical hot-pressing process, in which the MOF network is grown on the polyacrylonitrile (PAN) electrospun fibrous membrane through an automated layer-by-layer (LbL) assembly spraying technique. The MOF network not only promises excellent mechanical properties and high thermal stability but also enhances ionic conductivity due to the resulting interconnected Li + transport paths. In addition, such electrolyte also demonstrates a high Li + transference number (0.68) and a wide electrochemical stability window (5.2 V). As a result, the assembled Li//Li symmetrical cell shows an ultrastable cycling performance even after cycling for 1800 h. Furthermore, its LiFePO 4 //Li full cell exhibits a high capacity of up to 120 mAh g −1 at 1 C and 30 °C and can maintain a rather high capacity retention of 95% after 160 cycles. This study provides some inspirations for the fabrication of high performance polymer-based solid-state electrolytes in a large scale.

Solid-state lithium metal batteries (SSLMB) are regarded as the most promising among lithium batteries to serve the automotive industry with their lighter weight, safety, durability, higher energy density, and faster rate of charge enabling emobility. Regarding battery components, novelty in electrode materials is through improving materials from conventional lithium batteries; however, the fundamental differentiator for SSLMB is the solid-state electrolytes (SSEs). SSE development is reviewed here with three main subcategories taking the stage, viz. ceramic electrolytes, polymer electrolytes, and soft sulfur-based electrolytes, and hybrid solutions derived from the combinations above. Lithium dendritic issues remain as the major bottleneck in the development of lithium metal batteries (LMBs) although SSEs are being utilized in the cells. Based on the existing investigations, this paper presents a comprehensive review on the factors that may cause the formation and propagation of the lithium dendrites in SSEs, the lithium dendrites growth mechanisms, and approaches to mitigate the issues. Herein, the key players are also being reviewed along with their recent progresses in researching and developing a viable technology of solid-state battery (SSB) toward mass-production and commercialization into the market. Perspectives and insights for further exploration in this research area are also presented within this Review.
