“…Different kinds of organic and inorganic components have been used in inorganic/organic composite electrolytes to explore possibilities of enhancing ionic conductivity, broadening voltage window, and improving electrode/ electrolyte interfacial compatibility. 18,[208][209][210][211][212][213][214] However, the flexible batteries with composite electrolytes under commercially required tests are rather limited, since the materials, structure, and configuration design still cannot withstand significant deformation, especially taking energy density and safety into considerations.…”

Smart energy storage has revolutionized portable electronics and electrical vehicles. The current smart energy storage devices have penetrated into flexible electronic markets at an unprecedented rate. Flexible batteries are key power sources to enable vast flexible devices, which put forward additional requirements, such as bendable, twistable, stretchable, and ultrathin, to adapt mechanical deformation under the working conditions. This review summarizes the recent advances in construction and configuration of flexible batteries and discusses the general metrics to benchmark various flexible batteries with different materials and chemistries. Moreover, we present advanced prototype flexible batteries developed by some companies to afford general envision of the technological status. Lastly, the critical points are summarized in the development of flexible batteries and remaining challenges are also presented for the future design of flexible batteries in practical perspectives.

“…This mechanism generally exists in various systems, such as LLZO-PVDF-LiTFSI, [140] LLZTO-PPC-LiTFSI, [141] TiO 2 -PEO-LiClO 4 , [142] LLZO-PVDF-LiClO 4 . [143,144] Another great benefit of the addition of ceramic modifiers is the improvement of electrolyte stability and the ability to prevent Li dendrite growth, [145] which are manifested in the increase of polymer decomposition voltage [146,147] and the decrease of current density at the electrolyte/anode interface. Almost all studies mention improvements in these aspects, although some did not suggest that the addition of ceramic modifiers was beneficial for the reduction of polymer crystallinity and the improvement of lithium-ion conductivity .…”

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.

“…[ 23–25 ] In this case, mechanical properties of SPEs are usually enhanced by in‐situ cross‐linking or combining with inorganic ceramics. [ 26–31 ] In‐situ cross‐linking method not only enhances the mechanical properties of 3D network structure SPEs but also simplifies the fabrication process and reduces the interfacial resistance. [ 26–27 ] Furthermore, to inhibit lithium dendrite growth, numerous kinds of fillers are introduced to improve the mechanical modulus and ionic conductivity of SPEs.…”

Solid-state polymer electrolytes (SPEs) with flexibility, easy processability, and low cost have been regarded as promising alternatives for conventional liquid electrolytes in next-generation high-safety lithium metal batteries. However, SPEs generally suffer poor strength to block Li dendrite growth during the charge/discharge process, which severely limits their wide practical applications. Here, a rational design of 3D cross-linked network asymmetric SPE modified with a metal-organic framework (MOF) layer on one side is proposed and prepared through an in-situ polymerization process. In such unique asymmetric SPEs, the nanoscale MOF layer acts as a shield that effectively suppresses the growth of Li dendrites and regulates the uniform Li + transport, and the polymer electrolyte can be scattered in the whole cell to endow the smooth transmission of Li +. As a result, the asymmetric SPE exhibits high ionic conductivity, wide electrochemical window, high thermal stability and safety, which endows the Li/Li symmetrical cell with outstanding cyclic stability (operate well over 800 h at a current density of 0.1 mA cm −2 for the capacity of 0.1 mAh cm −2).
