“…In addition, P(VDF−TrFE) exhibits more flexibility than commonly used PVDF, which is suitable as a self‐support skeleton combined with sulfide electrolytes to create ultra‐thin and high‐conductivity solid electrolyte membrane. Nan and his colleague constructed a three‐dimensional poly(vinylidene fluoride−cotrifluoroethylene) P(VDF−TrFE) network composed of argyrodite Li 6 PS 5 Cl (LPSCl) by electrospinning‐infiltration‐hot‐pressing method [70] . Interaction of polar P(VDF−TrFE) and LPSCl not only generates high ionic conductivities, but also produce good mechanical and reach the thickness of 30–40 μm.…”

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.

“…Although the sulfide SEs can dissolve in solvents and be infiltrated in sheet‐type cathode (Figure 2d), the small amount of SE and poor contact between SE and CAMs cannot construct a considerable ionic transfer network [54,55] . it should be noted that ASSBs based on flexible and deformable polymer electrolytes can contact with the sheet‐type electrode closely, but ASSBs based on inorganic SEs membrane cannot be suited well with the sheet‐type electrode [56–58] . The surface of inorganic SEs membrane prepared by more than 99 % SEs powder and a very small amount of binder is still composed of powder in the microscopic morphology as shown in Figure 2e, which is quite different from the surface of polymer electrolyte [59,60] .…”

All‐solid‐state batteries (ASSBs) based on inorganic solid electrolytes (SEs) are one of the most promising strategies for next‐generation energy storage systems and electronic devices due to the higher energy density and intrinsic safety. However, the poor solid‐solid contact and restricted chemical/electrochemical stability of inorganic SEs both in cathode and anode SE interfaces cause contact failure and the degeneration of SEs during prolonged charge‐discharge processes. As a result, the increasing interface resistance significantly affects the coulombic efficiency and cycling performance of ASSBs. Herein, we present a fundamental understanding of physical contact and chemical/electrochemical features of ASSB interfaces based on mainstream inorganic SEs and summarize the recent work on interface modification. SE doping, optimizing morphology, introducing interlayer/coating layer, and utilizing compatible electrode materials are the key methods to prevent side reactions, which are discussed separately in cathode/anode‐SE interface. We also highlight the constant extra stack pressure applied during ASSB cycling, which is important to the electrochemical performance. Finally, our perspectives on interface modification for practical high‐performance ASSBs are put forward.

Tailoring Practically Accessible Polymer/Inorganic Composite Electrolytes for All-Solid-State Lithium Metal Batteries: A Review

Highlights The current issues and recent advances in polymer/inorganic composite electrolytes are reviewed. The molecular interaction between different components in the composite environment is highlighted for designing high-performance polymer/inorganic composite electrolytes. Inorganic filler properties that affect polymer/inorganic composite electrolyte performance are pointed out. Future research directions for polymer/inorganic composite electrolytes compatible with high-voltage lithium metal batteries are outlined. Abstract Solid-state electrolytes (SSEs) are widely considered the essential components for upcoming rechargeable lithium-ion batteries owing to the potential for great safety and energy density. Among them, polymer solid-state electrolytes (PSEs) are competitive candidates for replacing commercial liquid electrolytes due to their flexibility, shape versatility and easy machinability. Despite the rapid development of PSEs, their practical application still faces obstacles including poor ionic conductivity, narrow electrochemical stable window and inferior mechanical strength. Polymer/inorganic composite electrolytes (PIEs) formed by adding ceramic fillers in PSEs merge the benefits of PSEs and inorganic solid-state electrolytes (ISEs), exhibiting appreciable comprehensive properties due to the abundant interfaces with unique characteristics. Some PIEs are highly compatible with high-voltage cathode and lithium metal anode, which offer desirable access to obtaining lithium metal batteries with high energy density. This review elucidates the current issues and recent advances in PIEs. The performance of PIEs was remarkably influenced by the characteristics of the fillers including type, content, morphology, arrangement and surface groups. We focus on the molecular interaction between different components in the composite environment for designing high-performance PIEs. Finally, the obstacles and opportunities for creating high-performance PIEs are outlined. This review aims to provide some theoretical guidance and direction for the development of PIEs.
