“…[65] Triacrylonitrile diacrylate crosslinked polyacrylonitrile polyethyleneimine (PANÀ PEI) was used as a nanofiber membrane to prepare a solid electrolyte membrane by electrospinning (Figure 3b). [52] The nitrile from PAN undergoes amidation reactions compounded with PEI, as well as the PEI also provides an acidic site in the solvent. This unique crosslinking structure not only makes use of the branch PEI of the flexible skeleton but also helps to improve the mechanical properties of the fiber membrane.…”

Solid‐state polymer electrolytes (SPEs) for all‐solid‐state batteries (ASSBs) have received considerable attention owing to excellent processability, good flexibility, high safety levels, and superior thermal stability. However, the practical application of SPEs is currently restricted by their low ionic conductivity, narrow electrochemical oxidation window, and poor long‐term stability of lithium (Li) metal. These challenges are mainly related to the polymer molecular structures, the dynamic of the polymer electrolyte, and the polymer compound stability at the electrode‐electrolyte interface. In this review, we provide recent strategies and discuss strategies of interest for applications to high‐energy‐density ASSB, particularly the molecular design, ion‐transport dynamic mechanisms of solid polymer electrolytes, and organic‐inorganic composite. Based on recent work, perspectives on future research directions are discussed for developing solid polymer electrolytes.

“…Calendaring not only increased the contact area between SPE and lithium anode but also formed a highly ionic conductive interface containing LiF and Li 3 N, which was beneficial to reduce the interface resistance and alleviate the formation of lithium dendrites. Similarly, cellulose nanofibers, lithiated organic nanofiber films, PVDF-HFP/PAN blend films, PVDF-HFP/PAN/PVDF-HFP electrospun sandwich films, and cross-linked PAN-PEI nanofiber films have also been reported as supporting skeletons, which significantly improved the overall performance of SPEs. What is more interesting is that Yang et al prepared Cu 2+ -modified one-dimensional nanocellulose, which realized the independent transport of Li + along the cellulose direction, and the Li + transport mechanism was similar to the diffusion mechanism of inorganic electrolytes, getting rid of the limitation that Li + transport in polymer electrolytes depended on the movement of chain segments …”

Lithium metal is regarded as the most potential anode material for improving the energy density of batteries due to its high specific capacity and low electrode potential. However, the practical application of lithium-metal anodes (LMAs) still faces severe challenges such as uncontrollable dendrites growth and large volume expansion. The development of functional nanomaterials has brought opportunities for the revival of LMAs. Among them, nanofibrous materials show great application potential for LMAs protection due to their distinct functional and structural features. Here, the latest research progress in nanofibrous materials for LMAs is systematically outlined. First, the problems existing in the practical application of LMAs are analyzed. Then, prospective strategies and recent research progress toward stable LMAs based on nanofibrous materials are summarized from the aspects of artificial protective layers, three-dimensional frameworks, separators, and solid-state electrolytes. Finally, the future development of nanofibrous materials for the protection of lithium-metal batteries is summarized and prospected. This review establishes a close connection between nanofibrous materials and LMA modification and provides insight for the development of high-safety lithium-metal batteries.

“…The SSPEs exhibited considerable potential for solving these problems. [49] However, widely reported PEO-based SSPEs cannot satisfy the increasing requirements for ion transfer in commercial applications. Poly(tetrahydrofuran) with various compositions (denoted as xPTHF) was designed and employed as an SSPE for LIBs by Bao et al (Figure 14a,b).…”

Lithium‐based batteries (LBBs) have virtually dominated the energy storage market for electronic products and electric vehicles. In these batteries, the critical roles of polymers cannot be ignored. In this article, state‐of‐the‐art developments and perspectives for improving the safety and stability of LBBs using polymers are summarized. These materials are particularly used as separator decorations, solid‐state electrolytes, binders, and fire retardants. Polymers exhibit excellent performance as binders for Si anodes because of their long chains and high adhesion ability. This review focuses on the application of polymers to Li–S batteries based on their fundamental electrochemistry and the challenges arising from the dissolution of polysulfides. In addition, the dendrite growth inhibition ability and mechanism of polymeric artificial solid electrolyte interphase film and solid‐state electrolytes are described. The performance of polymer as fire retardant and the mechanism for solid‐state polymer electrolytes are elaborated. Finally, the perspectives on the potential of polymers for LBBs and energy storage because of their outstanding plasticity and chemical controllability are presented.
