“…An integrated electrolyte/electrode architecture was explored for ASSLSBs in order to improve the interfacial stability between electrode and electrolyte. [ 152 ] A composite bilayer framework composed of a 1D Li 0.33 La 0.557 TiO 3 (LLTO) ceramic nanofiber/PEO composite electrolyte was laminated to a 3D flexible carbon nanofiber/sulfur (CNF/S) cathode (Figure 14d). Introduction of ceramics promoted segmental mobility of the host PEO, while LLTO nanofibers provided abundant fast continuous Li ion conductive pathways.…”

Polymer‐based solid electrolytes (PSEs) have attracted tremendous interests for the next‐generation lithium batteries in terms of high safety and energy density along with good flexibility. Remarkable performances have been demonstrated in PSEs, which endowed PSEs with the potential to replace liquid electrolytes to meet the market demands. In this review, polymer matrices, different polymer architectures, and functional filler materials used in PSEs are discussed to explore the design concepts, methodologies, working mechanisms, and pros and cons of various PSEs. In addition, their recent notable applications in all‐solid‐state lithium ion batteries, lithium–sulfur batteries, suppression of lithium dendrites, and flexible lithium batteries are also introduced. Finally, the challenges and future prospects are sketched to provide strategies to explore novel PSEs for high‐performance all‐solid‐state lithium batteries.

“…However, the poor interfacial contacts with electrodes and the deposition of Li inside some ISEs prevent their real‐world application . In addition, the brittle nature poses challenges in manufacturing, and the mass density and thickness of ISEs are both too high to enable high energy density 6b,7. Conversely, SPEs incorporating polymer matrix and Li salts exhibit advantages such as flexibility, good adhesion to electrodes, low cost, lightweight, and manufacturing scalability, which makes them promising for use in the practical applications such as portable devices and electric vehicles 5a,8.…”

All‐solid‐state batteries are promising candidates for the next‐generation safer batteries. However, a number of obstacles have limited the practical application of all‐solid‐state Li batteries (ASSLBs), such as moderate ionic conductivity at room temperature. Here, unlike most of the previous approaches, superior performances of ASSLBs are achieved by greatly reducing the thickness of the solid‐state electrolyte (SSE), where ionic conductivity is no longer a limiting factor. The ultrathin SSE (7.5 µm) is developed by integrating the low‐cost polyethylene separator with polyethylene oxide (PEO)/Li‐salt (PPL). The ultrathin PPL shortens Li+ diffusion time and distance within the electrolyte, and provides sufficient Li+ conductance for batteries to operate at room temperature. The robust yet flexible polyethylene offers mechanical support for the soft PEO/Li‐salt, effectively preventing short‐circuits even under mechanical deformation. Various ASSLBs with PPL electrolyte show superior electrochemical performance. An initial capacity of 135 mAh g−1 at room temperature and the high‐rate capacity up to 10 C at 60 °C can be achieved in LiFePO4/PPL/Li batteries. The high‐energy‐density sulfur cathode and MoS2 anode employing PPL electrolyte also realize remarkable performance. Moreover, the ASSLB can be assembled by a facile process, which can be easily scaled up to mass production.

“…One of these new pathways is the ability to synthesize and incorporate lithium-ion-conducting solid-state materials within a given polymer matrix. [100][101][102][103] Thus, flexible solid batteries become a reality, even more so with batteries delivering energy densities of up to 281 Wh kg À1 . [100] Nevertheless, to achieve higher energy densities one must produce thinner electrolyte layers, thus compromising the mechanical integrity of the flexible battery or run the battery at elevated temperatures.…”

Herein, three electrolyte families (liquid, polymer, and ceramic) are compared and their future perspectives in research and application are discussed. First, the transport mechanism for each family is presented, as their beneficial and taxing properties stem from the differences in these mechanisms. Following a discussion of each group, their advantages, and limitations, a clear conclusion can be drawn on the need to focus on research on solid electrolytes, which present brighter prospects in terms of significant future advances in lithium‐based battery systems. Yet, in a more realistic perspective based on current work by companies such as Samsung, Solid Power, and QuantumScape, it is our understanding that the hybridization of polymer and solid electrolytes will likely dominate practical electrolyte chemistries, at least in the near future, given that the synergetic properties of the two families are larger than their single parts. Inevitably, solid‐state electrolytes will dominate, mainly in electric vehicles and future lithium battery chemistries.
