“…[46e] Although the enhanced ionic conductivity was obtained, the Li + migration process within these copolymers with multiple functional groups remains unclear. To address this problem, molecular dynamic (MD) simulations and density functional theory (DFT) calculations have been used to explore the Li + migration mechanism in copolymers consisting of poly (ethylene glycol) methyl ether methacrylate (PEGMA) and vinylene carbonate (VC) by Zhao et al [47] Their results indicate that the VC group with ethylene carbonate (EC) units can release more free Li + owing to the weak interaction, which cooperates with PEGMA that possesses ethyoxyl (EO) groups to form a continuous Li + migration path (Figure 2c), resulting in excellent ionic conductivity and desirable Li + transference number. These results indicate that new polymer-based SEs with excellent overall performance and high ionic conductivity near/under ambient temperatures [46c] can be obtained by crosslinking polymerization and co-polymerization routes to achieve combined advantages of individual functional groups.…”

“…[ 48a,53c,58,64c,150 ] Therefore, only the main electrochemical performance are reported, while other properties, such as safety and energy density, are usually difficult to identify. Additionally, within the vast majority of reported high‐voltage ASSLBs, far more Li metal anodes are used than the actual amount required, which is not desirable in terms of energy density. The thickness of SEs is generally relatively high (>25 µm), [ 47,65a,82a,91 ] which is conducive to effectively inhibiting the growth of Li dendrites but is not beneficial to the overall energy density of ASSLBs. Therefore, the thickness of SEs should be carefully controlled to achieve a balance between obtaining an overall high energy density and effectively suppressing Li dendrites.…”

All-solid-state lithium batteries (ASSLBs) with nonflammable solid electrolytes (SEs) deliver greatly enhanced safety characteristics. Furthermore, ASSLBs composed of cathodes with high working voltages, such as LiCoO 2 , LiNi x Co y Mn z O 2 (x + y + z = 1, NCM), LiNi x Co y Al z O 2 (x + y + z = 1, NCA), LiMn x Fe y PO 4 (x + y = 1, LMFP), and LiNi 0.5 Mn 1.5 O 4 (LNMO), and a lithium metal anode can achieve comparable or better performance compared with that of LLBs in terms of energy density. Therefore, high-voltage ASSLBs have been regarded as the most promising next-generation batteries. Although significant progress has been achieved in high-voltage ASSLBs research, their development still faces multiple challenges. To facilitate further effective and target-oriented research on highvoltage ASSLBs, a summary of recent research progress is urgently needed. In this review, recent research progress in high-voltage ASSLBs is summarized from the perspectives of SEs modification, interfacial challenges and their corresponding solutions for cathodes, and high-voltage composite cathode design for practical applications. Finally, the authors' perspectives on the state of current ASSLBs research, aiming to propose possible research directions for the future development of high-voltage ASSLBs.

“…In addition, the brittleness of the inorganic particles themselves makes even small fluctuations may lead to the destruction of their structures, which greatly hinder the commercialization of all-solid-state batteries [ 15 ]. In comparison, SPE exhibits excellent interface stability with the electrode and good processability due to the flexibility of the polymer [ 16 , 17 ]. In the most widely studied polyethylene oxide (PEO) polymer electrolyte, lithium ions can be transported along the PEO molecular chain through the complexation-decomplexation with the ether oxygen bond [ 18 , 19 ].…”

All-solid-state electrolytes have received extensive attention due to their excellent safety and good electrochemical performance. However, due to the harsh conditions of the preparation process, the commercial production of all-solid-state electrolytes remains a challenge. The outbreak of the novel coronavirus pneumonia (COVID-19) has caused great inconvenience to people, while also allowing soft, lightweight and mass-producible non-woven fabrics in masks come into sight. Here, a polymer/polymer solid composite electrolyte is obtained by introducing the polyamide 6 (PA6) microfiber non-woven fabric into PEO polymer through the hot-pressing method. The addition of the PA6 non-woven fabric with lithium-philic properties can not only reduce the crystallinity of the polymer, but also provide more functional transmission sites and then promote the migration of lithium ions at the molecular level. Moreover, due to the sufficient mechanical strength and flexibility of the PA6 non-woven fabric, the composite electrolyte shows excellent inhibition ability of lithium dendrite growth and high electrochemical stability. The novel design concept of introducing low-cost and large-scale production of non-woven fabrics into all-solid-state composite electrolytes to develop high-performance lithium metal batteries is attractive, and can also be broadened to the combination of different types of polymers to meet the needs of various batteries.

Comprehensive SummaryWith the rapid development of solid‐state batteries, solid‐state polymer electrolytes (SPEs) have attracted widespread attention due to their excellent environmental friendliness, designability, and forming film ability. However, due to the limited conductive path of polymers, lithium‐ion diffusion kinetics are limited, and low ion conductivity is a huge challenge for SPEs in practical applications. This work provides a polyethylene oxide (PEO) based polymer electrolyte, which has multiple paths of ion diffusion caused by organic polymer framework of poly(hexaazatrinaphthalene) (PHATN). The unique porous channel, the specific surface characteristics, the coordination of ‐C=N‐ groups in PHATN with Li+, combined with the mobility of PEO segments, make the SPEs have a good ability to conduct Li+. Interestingly, the PHATN‐PEO/lithium bis(trifluoromethanesulfonyl) imide (LiTFSI) composite electrolytes exhibit excellent electrochemical properties. At room temperature, the conductivity of PHATN‐PEO electrolyte can reach 1.03 × 10–4 S·cm–1, which is greatly improved compared with 3.9 × 10–6 S·cm–1 of PEO. Delightedly, the lithium‐ion transference number of PHATN‐PEO electrolyte achieves 0.61, and the electrochemical window increases to 4.82 V. The LFP/1%PH‐PEO/Li solid‐state batteries show good electrochemical cycles. This work reveals an efficient stratagem for the design of polymer solid‐state electrolytes.
