“…[158][159][160] The nucleation and growth of Li are uncontrollable during cycling, while the SEI on the Li surface barely prevents the formation of Li dendrites. [161][162][163] Therefore, dendrites still challenge the lifespan and electrochemical performance of ASSBs, even for batteries with high mechanical strength ceramic electrolytes.…”

Compared with conventional liquid batteries, all-solid-state batteries (ASSBs) show great promise for enabling higher safety in electric vehicles without compromising operational durability and range. As a key component of ASSBs, solid-state electrolytes (SSEs) need high ionic conductivity and favorable interfacial compatibility between electrodes and SSEs. In the recent decade, numerous efforts have been devoted to SSE advancement and fruitful achievements have been made, particularly regarding metal anode-oriented SSEs with high energy density. This review focuses on the historical process of SSEs employed in ASSBs. The new understanding and origins for the enhanced ionic conductivity and mechanical properties of SSEs are first summarized. As to the cathode/SSE interface, its decomposition mechanism and modification strategies are analyzed. As to the interfacial issues of SSEs with anodes, the mechanisms of dendrite formation and penetration into the SSEs are discussed in detail. Additionally, assisted by a library of big data sources, contributions are systematically highlighted from different countries, institutions, and corresponding authors to significantly advance SSE progress, and certain insights are provided into the underlying relationships between various items in a collective manner. Finally, current challenges and potential strategies are identified for the future development of SSEs in ASSBs.

“…However, electrochemical properties of pure PVDF‐HFP‐based SPEs cannot meet the requirements. Therefore, many PVDF‐HFP‐based solid composite electrolytes (SCEs) composed of ceramic fillers and lithium salts have been developed, such as PVDF‐HFP/LLZO, 18,19 PVDF‐HFP/LLBZO, 20 PVDF‐HFP/LLZTO, 21 PVDF‐HFP/BN, 22 and so on. Moreover, PVDF‐HFP polymer electrolyte can be further modified by blending, crosslinking and adding other ceramic fillers.…”

Solid polymer electrolytes have the merits of high safety and energy density and lightweight. Therefore, they gradually become the key for commercial applications of solid batteries. In this study, a new type of solid composite electrolyte (SCE) is prepared by adding Li 0.33 La 0.557 TiO 3 (LLTO) nanorods into poly(vinylidene fluoride-co-hexafluoropropylene (PVDF-HFP) matrix. This SCE displays excellent thermal stability and mechanical properties. Moreover, it has been proven to sufficiently suppress the growth of lithium dendrites. When the content of the LLTO nanorods reaches 10 wt%, the SCE delivers a high ionic conductivity of 1.21 × 10 −4 S cm −1 at 25 C and the electrochemical stability window of 4.7 V (vs Li + /Li). The NCM622/SCE/Li solid-state lithiumion battery delivers a discharge specific capacity of 129.1 mAh g −1 at 0.5 C after 100 cycles, and the coulombic efficiency reaches 99%. These results demonstrate that the SCE is expected to become one of the most hopeful candidates for the coming generation of solid-state lithium-ion batteries.

“…Beside, nitride, [ 166 ] carbide [ 167 ] and metal‐organic framework (MOF) [ 168 ] are also employed as inorganic inert fillers for CPE due to their uniform microstructure, large surface area, low electronic conductivity, abundant functional groups on the mesoporous surface, as well as, robust chemical and thermal stability. In combination with lithium conductive polymers, inorganic fillers inhibit the crystallinity of PEO and facilitate the mobility of the ether segments, improving the ionic conductivity.…”

In the development of solid‐state lithium batteries, solid polymer electrolyte (SPE) has drawn extensive concerns for its thermal and chemical stability, low density, and good processability. Especially SPE efficiently suppresses the formation of lithium dendrite and promotes battery safety. However, most of SPE is derived from the matrix with simple functional group, which suffers from low ionic conductivity, reduced mechanical properties after conductivity modification, bad electrochemical stability, and low lithium‐ion transference number. Appling macromolecular design with multiple functional groups to polymer matrix is accepted as a strategy to solve the problems of SPE fundamentally. In this review, macromolecular design based on lithium conducting groups is summarized including copolymerization, network construction, and grafting. Meanwhile, the construction of single‐ion conductor polymer is also focused herein. Moreover, synergistic effects between the designed matrix, lithium salt, and fillers are reviewed with the objective to further improve the performance of SPE. At last, future studies on macromolecular design are proposed in the development of SPE for solid‐state batteries with high energy density and durability.
