Combining the strengths of inorganic solid-state electrolytes and solid-state polymer electrolytes, composite solid electrolytes (CSEs) are practically more viable for commercial applications. However, only a few efforts have achieved high-voltage (&gt;4.3 V vs. Li\/Li<sup>+<\/sup>) LMBs with distinguished comprehensive performance, which is mainly attributed to the fact that CSEs with both high ionic conductivity and good compatibility with electrodes are difficult to obtain. Furthermore, the relatively tedious fabrication process, such as the ex-situ solution casting technique accompanied by the use of noxious organic solvents, can hardly meet the practical needs of large-scale commercial production.<\/p>\n<p>                                                                                Recently, Prof. Guanglei Cui developed novel CSE (denoted as P(PDEM-D4)-CSE) comprising a star-shaped siloxane-based electrolyte coupled with LLZTO ceramic filler. P(PDEM-D4)-CSE was prepared through facile in-situ polymerization of the electrolyte precursor solution containing 2,4,6,8-tetramethyl-2,4,6,8-tetravinylcyclotetrasiloxane (D4), poly(ethylene glycol) methyl ether acrylate (PDEM), lithium difluoro(oxalate)borate (LiDFOB), and LLZTO particles. <\/p>\n<p>Among them, D4, as a part of the polymer backbone, can effectively increase the free volume for the segmental motions of polymer chains, thereby enhancing ionic conductivity. PDEM, as a Li<sup>+<\/sup> carrier, provides channels for Li-ion transport. LiDFOB, as the Li source, supplies Li<sup>+<\/sup> and DFOB<sup>\u2212<\/sup> and participates in the construction of the interface film. LLZTO, as an active ceramic filler, not only enhances the segmental motion of the polymer matrix by reducing crystallinity and increasing the free volume of the polymer matrix, which helps construct more channels for ion transport, but also acts as the anionic receptor that promotes the dissociation of Li salts and the increase of free Li-ion concentration.<\/p>\n<p>P(PDEM-D4)-CSE exhibits high ionic conductivities (i.e., 4.0 \u00d7 10<sup>\u22125<\/sup>, 1.68 \u00d7 10<sup>\u22124<\/sup>, and 5.73 \u00d7 10<sup>\u22124<\/sup> S\u00b7cm<sup>\u22121<\/sup> at 30\u00b0C, 60\u00b0C, and 100\u00b0C, respectively). Furthermore, this CSE can induce more uniform, reversible Li plating\/s<a href=\"https:\/\/buradabiliyorum.com\/en\/category\/trip-and-travel\/\" data-internallinksmanager029f6b8e52c=\"10\" title=\"Trip &amp; Travel\" target=\"_blank\" rel=\"noopener\">trip<\/a>ping behaviors, mainly owing to the formation of compatible solid electrolyte interface. As a result, the as-developed CSE enables long-life 4.4 V-class solid-state LMBs based on a LiCoO<sub>2<\/sub> cathode, which deliver 79.7% capacity retention and 99.74% average Coulombic efficiency after 500 cycles at a 0.5 C rate.
