“…On the one hand, SE can offer good mechanical strength and non-flammability, rendering the safety of ASSLBs. On the other hand, Li anode possesses an unparalleled theoretical capacity (3860 mA h g À1 ) and a low redox potential (À3.04 V vs. SHE) [8][9][10][11][12][13], which is significant to the achievement of high energy density for ASSLBs [14][15][16][17].…”

“…Therefore, using PAN, PMMA, PVDF, and other polymers with higher decomposition voltage to combine with ceramic materials can get a better effect. [124] Zhang et al prepared the C/PCEs of LLZTO/PVDF/LiTFSI, which can enlarge the electrochemical window to 4.8 V. [125] Zhu et al adding the MIL-53(Al) as the modifier into the PEO electrolyte, the obtained C/PCEs can work at a high potential of 5.10 V at 120°C. [126] Hu et al synthesize the C/PCEs with thiol-modified silica nanoparticles and poly(ethylene glycol) diacrylate via thiol-acrylate photopolymerization under UV irradiation.…”

“…Better than PEO, the decomposition voltage of the PAN system is generally between 4.3‐ 5.0 V (vs. Li/Li + ), and the electrochemical window of PMMA series gel polymer electrolyte is generally above 4.6 V (vs. Li/Li + ). Therefore, using PAN, PMMA, PVDF, and other polymers with higher decomposition voltage to combine with ceramic materials can get a better effect [124] . Zhang et al.…”

The design and fabrication of solid‐state electrolytes (SSEs) with high ionic conductivity is the most crucial obstacle for all‐solid‐state lithium batteries (ASSLBs). However, though polymer SSEs have the advantages of effective interfacial contact, polymer ASSLBs have not been able to deliver performance comparable to conventional lithium‐ion batteries (LIBs) due to slow ion transport within the polymer framework. In contrast, the high inherent ionic conductivity of ceramic SSEs is limited by the poor electrolyte/electrode interfacial contact. Therefore, the concept of ceramic/polymer composite electrolytes (C/PCEs) was proposed to combine the advantages of these two electrolytes and simultaneously overcome their weaknesses. This work reviews the recent progress in C/PCEs development according to the morphology of the ceramic components in C/PCEs. In this review, we investigate the inherent relationship between the structures of C/PCEs and the performance of the resultant SSEs, and subsequently conclude some general C/PCE design principles for future SSEs.

“…[37] To this end, several previous studies have made attempts through directly casting SPEs onto the electrode surface or their mixed slurry, and fusing electrodes and electrolytes via heating or hot pressing. [36,[38][39][40][41] Although the interfacial adhesion is reinforced, there remains critical challenges. These works used composite powder electrodes of active materials, electrolyte slurry and conductive additives, wherein active materials were wrapped with binders and conductive additives.…”

Solid-state lithium batteries (SSLBs) are promising owing to enhanced safety and high energy density but plagued by the relatively low ionic conductivity of solid-state electrolytes and large electrolyte-electrode interfacial resistance. Herein, we design a poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP)-based polymer-in-salt solid electrolyte (PISSE) with high room-temperature ionic conductivity (1.24 10 À4 S cm À1 ) and construct a model integrated TiO 2 /Li SSLB with 3D fully infiltration of solid electrolyte. With forming aggregated ion clusters, unique ionic channels are generated in the PISSE, providing much faster Li + transport than common polymer electrolytes. The integrated device achieves maximized interfacial contact and electrochemical and mechanical stability, with performance close to liquid electrolyte. A pouch cell made of 2 SSLB units in series shows high voltage plateau (3.7 V) and volumetric energy density comparable to many commercial thin-film batteries.
