“…Such a fairly little potential difference as low as 0.07 V usually represents a minor polarization, indicating a small internal cell resistance. 54 The LiFePO 4 /Li cell with PVDF-Li-LZ SSCEs also exhibits an excellent rate performance. As shown in Fig.…”

“…Similarly, taking above advantage of the MOFs, adding them to conventional polymer electrolytes (PEO/LiTFSI) which significantly improves the ionic conductivity of electrolyte at room temperature [126]. The solid-state polymer electrolyte prepared by the addition of MOF not only improves the ionic conductivity, the stability of the electrochemical window and the lithium-ion migration number [127][128][129], but also effectively resists the piercing of lithium dendrites [130]. MOFs are considered as a promising new electrolyte for all-solid-state batteries.…”

The application of rechargeable lithium batteries involves all aspects of our daily life, such as new energy vehicles, computers, watches and other electronic mobile devices, so it is becoming more and more important in contemporary society. However, commercial liquid rechargeable lithium batteries have safety hazards such as leakage or explosion, all-solid-state lithium rechargeable lithium batteries will become the best alternatives. But the biggest challenge we face at present is the large solid-solid interface contact resistance between the solid electrolyte and the electrode as well as the low ionic conductivity of the solid electrolyte. Due to the large relative molecular mass, polymers usually exhibit solid or gel state with good mechanical strength. The intermolecules are connected by covalent bonds, so that the chemical and physical stability, corrosion resistance, high temperature resistance and fire resistance are good. Many researchers have found that polymers play an important role in improving the performance of all-solid-state lithium rechargeable batteries. This review mainly describes the application of polymers in the fields of electrodes, electrolytes, electrolyte-electrode contact interfaces, and electrode binders in all-solid-state lithium rechargeable batteries, and how to improve battery performance. This review mainly introduces the recent applications of polymers in solid-state lithium battery electrodes, electrolytes, electrode binders, etc., and describes the performance of emerging porous polymer materials and materials based on traditional polymers in solid-state lithium batteries. The comparative analysis shows the application advantages and disadvantages of the emerging porous polymer materials in this field which provides valuable reference information for further development.

“…[23,24] In details, neat MOFs can absorb Li-containing compounds and transport Li þ through nanopores, so as to work as the lithium-ion conductors. [25][26][27] Additionally, the migration of Li þ in the polymer matrixes mainly relies on the motion of the polymeric chains and this happens mostly in amorphous phases. [28,29] By adding MOFs into SCEs, the regular arrangement of polymer chains can also be disordered for decreasing the crystallinity of polymer matrixes, which plays an important role for obtaining a high ionic conductivity.…”

Benefiting from employing solid composite electrolytes (SCEs), all‐solid‐state lithium‐ion batteries (ASSLBs) are recognized to occupy with high energy density and safety. Herein, a polymer‐based SCE membrane (SCE‐66@67) with core–shell structured metal–organic frameworks (MOFs) (UiO‐66‐NH2@67) as the fillers is presented. The SCE has combined the advantages of the two kinds of MOFs and shows a satisfying ionic conductivity (2.09 × 10−4 S cm−1 at 60 °C) and a wide electrochemical stability window of ≈5.0 V. The full cell (Li/SCE‐66@67/LiFePO4) also maintains a high capacity of 120.9 mAh g−1 at 3 C. This research might help to promote the development of future SCEs for ASSLBs.
