“…Growing research focuses on reducing the crystallinity to maintain the amorphous state of PEO-based SPEs. Many strategies have been tested, such as incorporation of ceramic or inorganic nanoparticles as fillers [20][21][22][23][24], introduction of roomtemperature ionic liquid [25], design of branched or star structures [26,27], synthesis of copolymers [28][29][30] or single-ion conducting electrolytes [31,32], use of new type of Li salts [33] and preparation of cross-linked polymers [34][35][36][37][38][39]. Nevertheless, the results at ambient temperature are still below the requirements for solid-state polymer electrolytes in lithium batteries, i.e.…”

Liqun Sun, et al.. Cross-linking network based on Poly(ethylene oxide): Solid polymer electrolyte for room temperature lithium battery. Journal of Power Sources, Elsevier, 2019, 420, pp. Abstract:In this paper, we develop a facile UV-derived in-situ dual-reaction to prepare a flexible poly(ethylene oxide) (PEO)-based solid polymer electrolyte (SPE), which is applied for ambienttemperature all-solid-state lithium battery. By modifying the amorphous domain of PEO through crosslinking with tetraglyme (TEGDME) and introducing a rigid linear oligomer of tetraethylene glycol dimethacrylate (TEGDMA) into the matrix, a SPE is obtained with high ionic conductivity (2.7 × 10 -4 S cm -1 at 24 °C) and enhanced mechanical strength. The as-prepared SPE shows superior electrochemical properties with decent lithium transference number of 0.56, wide electrochemical stability window above 5 V vs. Li + /Li and low interfacial resistance. By means of galvanostatic cycling studies in Li//Li symmetrical and LiFePO 4 //Li cells, we further demonstrate that the SPE exhibits excellent cycling performance with minimization of lithium dendrite formation.

“…Research has demonstrated that crosslinking can induce improvements in dimensional stability and increase dynamic storage modulus of polymer electrolytes [103]. Moreover, increases in the amorphous phase can be obtained in polymers through crosslinking, providing polymers with rubber-like characteristics [63,104,105]. Because of these benefits, numerous crosslinked polymers have been investigated for Li batteries, including polyether polymers [64,106], acrylate polymers [107] and polyurethane polymers [108].…”

In recent years, lithium batteries using conventional organic liquid electrolytes have been found to possess a series of safety concerns. Because of this, solid polymer electrolytes, benefiting from shape versatility, flexibility, low-weight and low processing costs, are being investigated as promising candidates to replace currently available organic liquid electrolytes in lithium batteries. However, the inferior ion diffusion and poor mechanical performance of these promising solid polymer electrolytes remain a challenge. To resolve these challenges and improve overall comprehensive performance, polymers are being coordinated with other components, including liquid electrolytes, polymers and inorganic fillers, to form polymer-based composite electrolytes. In this review, recent advancements in polymer-based composite electrolytes including polymer/ liquid hybrid electrolytes, polymer/polymer coordinating electrolytes and polymer/inorganic composite electrolytes are reviewed; exploring the benefits, synergistic mechanisms, design methods, and developments and outlooks for each individual composite strategy. This review will also provide discussions aimed toward presenting perspectives for the strategic design of polymer-based composite electrolytes as well as building a foundation for the future research and development of high-performance solid polymer electrolytes.

Due to high energy density, low cost, and nontoxicity, lithium-sulfur (Li-S) batteries are considered as the most promising candidate to satisfy the requirement from the accelerated development of electric vehicles. However, Li-S batteries are subjected to lithium polysulfides (LiPSs) shuttling due to their high dissolution in liquid electrolyte, resulting in low columbic efficiency and poor cycling performance. Moreover, the Li metal as an indispensable anode of Li-S batteries shows serious safety issues derived from the lithium dendrite formation. The replacement of liquid electrolytes with solid-state electrolytes (SSEs) has been recognized as a fundamental approach to effectively address above problems. In this review, the progress on applying various classes of SSEs including gel, solid-state polymer, ceramic, and composite electrolytes to solve the issues of Li-S batteries is summarized. The specific capacity of Li-S batteries is effectively improved due to the suppression of LiPSs shuttling by SSEs, while the rate and cycling performance remain relatively poor owing to the limited ionic conductivity and high interfacial resistance. Designing smart electrode/electrolyte integrated architectures, enabling the high ionic transportation pathway and compatible electrode/electrolyte interface, may be an effective way to achieve high performance solid-state Li-S batteries. and strategies have been attempted to address the above main issues of Li-S batteries, including using sulfur host materials, [4] unique separators [5] and interlayer, [6] composite of electrolyte, [7] novel binders, [8] etc. However, these approaches can only solve problems to a certain extent. Some review papers have concluded and commented on above potential solutions. [9] Recently, solid-state electrolytes (SSEs) including gel, solid-state polymer, ceramic, and composite electrolytes are attracting increasing interest for application in Li-S batteries to fundamentally solve the issues of Li-S batteries caused by liquid electrolyte. Furthermore, nonflammable solid electrolytes would improve the safety performance of Li-S batteries remarkably. In the past few years, more and more research work focused on applying SSEs in Li-S batteries to solve the LiPSs dissolution. [10] Some review papers about Li-S batteries have also emphasized the significance of SSEs. However, until now, there are few review papers specially summarizing the progress and prospect of the solid-state Li-S batteries.This review aims to provide an overview of SSEs for addressing the major drawbacks of Li-S batteries, including the electrochemical reaction process of S cathode and its corresponding problems as well as traditional solutions, the recent research progress of solid-state Li-S batteries using gel, solidstate polymer, ceramic, and composite electrolytes, and strategies for overcoming the deficiencies of solid-state electrolytes such as low room-temperature ionic conductivity and high Solid-State Electrolytes interfacial resistance. In addtition, the mechanism a...
