“…Meanwhile, PEO shows high viscosity, poor filmforming ability as well as narrow electrochemical window, which further hinder the LLZO-based/PEO SCEs for large scale application in real batteries. To explore LLZO-based/polymer SCEs with better properties, other novel types of polymers, such as poly(propylene carbonate) (PPC) [125][126][127][128] , poly(vinylidene fluoride) (PVDF) [129][130][131][132] , poly(vinylidene fluoride-hexafluoropropylene) (PVDF-HFP) [133][134][135][136][137] , poly(ethylene carbonate) (PEC) [138] , polyacrylonitrile (PAN) [139] , poly(methyl methacrylate) (PMMA) [140] , cross-linked polyethyleneglycol [141] , poly(ethylene glycol) diacrylate (PEGDA) [142] and mixed polymers [143][144][145] have been developed as the substrate for constructing novel LLZObased/polymer SCEs. Table 4 summarizes the intrinsic properties of the typical LLZO-based/novel polymer SCEs and the electrochemical performances of ASSLBs assembled by these novel SCEs.…”

“…The high voltage cells with an HSE of s@LLZAO-PEGDA with LiNi 1/3 Mn 1/3 Co 1/3 O 2 exhibited a stable capacity of 110 mAh/g after 250 cycles at a current density of 0.5 C at room temperature and with a high capacity retention of 97%. The excellent capacity retention was due to the good ionic conductivity of 3.9 × 10 −4 S/cm and large transference number of 0.61 for the prepared hybrid electrolytes (Yan et al, 2020).…”

Lithium-ion batteries (LIBs) have attracted worldwide research interest due to their high energy density and long cycle life. Solid-state LIBs improve the safety of conventional liquid-based LIBs by replacing the flammable organic electrolytes with a solid electrolyte. Among the various types of solid electrolytes, hybrid solid electrolytes (HSEs) demonstrate great promise to achieve high ionic conductivity, reduced interfacial resistance between the electrolyte and electrodes, mechanical robustness, and excellent processability due to the combined advantages of both polymer and inorganic electrolyte. This article summarizes recent developments in HSEs for LIBs. Approaches for the preparation of hybrid electrolytes and current understanding of iontransport mechanisms are discussed. The main challenges including unsatisfactory ionic conductivity and perspectives of HSEs for LIBs are highlighted for future development. The present review provides insights into HSE development to allow a more efficient and target-oriented future endeavor on achieving high-performance solid-state LIBs.

“…[242] Moreover, chemical crosslinking is an effective strategy to prepare network structural materials. For example, Yan et al [243] decorated acrylate functional groups on the surface of 1D Li 6.28 La 3 Al 0.24 Zr 2 O 12 (LLAZO). Then, the modified LLAZO was covalently cross-linked with the PEGDA matrix via thermalinitiated polymerization.…”

self-discharge rates. [1-3] LIBs permeate nearly every aspect of human life. They are widely used in portable electronics (e.g., smartphones, smart-watches, and laptops), transportation (e.g., electric and hybrid vehicles), and biomedical applications (e.g., cardiac pacemakers and cochlear implants). In light of these achievements, J.B. Goodenough, M.S. Whittingham, and A. Yoshino won the 2019 Nobel prize in chemistry. [4] Despite the considerable success of conventional LIBs, their operational regime is typically around room temperature (RT). Operating at low (<0 °C) or high (>60 °C) temperatures usually deteriorate the performance and leads to safety risks. [5] We should also note that commercial LIBs are highly hazardous as they can ignite and explode in case of an accident, overheating, and overcharging, requiring more stringent safety standards, e.g., wide temperature operability and nonflammability. For example, electric vehicles require battery systems that can deliver a stable performance while maintaining a high energy density even in extreme climates, such as cold mountainous areas, where the temperatures can be as low as −40 °C, and hot deserts, where equipment exposed to sunlight can reach temperatures exceeding 70 °C. [6] Moreover, task-specific applications call for reliable energy storage solutions at extreme temperatures, including subsurface exploration (such as for mineral, oil, and gas), aerospace engineering, safety and rescue, and sterilizable medical devices. [2] Conventional LIBs are composed of a positive electrode or cathode (e.g., LiFePO 4 (LFP), LiNi x Mn y Co z O 2 (x + y + z = 1, NMC) and LiCoO 2 (LCO)), an electrolyte (including solvents, Li salts, and additives), a separator (typically a polyolefin membrane), and a negative electrode or anode (e.g., graphite and Li 4 Ti 5 O 12 (LTO)). Generally, the electrode materials are nonflammable and thermal stable (>300 °C). While the polyolefin membrane will melt/shrink over 120 °C, the commercial separators composited with ceramic nanoparticle (e.g., SiO 2 and Al 2 O 3) have been developed to reduce thermal shrinkage when exposed to overheating. [7,8] Therefore, the major challenge of commercial LIBs at extreme operating temperatures comes to the electrolyte. Carbonates are commonly used as solvents for conventional LIB electrolytes. However, these compounds are Li-ion batteries (LIBs) are the energy storage systems of choice for portable electronics and electric vehicles. Due to the growing deployment of energy storage solutions, LIBs are increasingly required to function safely and steadily over a broad range of operational conditions. However, the conventional electrolytes used in LIBs will malfunction when the temperatures fall below zero or elevate above 60 °C. Further, conventional electrolytes are toxic and flammable, leading to severe safety risks, especially in the case of an accident or overheating. Therefore, an ever-growing body of research has been dedicated to the development of electrolytes characterized by high ionic conduct...
