“…PEO-based polymer electrolyte, on the other hand, has an issue with a dramatic fall in ionic conductivity at room temperature due to PEO crystallisation, even if it has a good ionic conductivity at temperatures above 60 °C. A variety of research groups reported using various methods to boost conductivity, such as adding inorganic fillers [5][6][7], gel electrolyte [8] and grafted polymers [9,10].…”

A terpolymer, poly(ethylene oxide-co-propylene oxide-co-allyl glycidyl ether) (P(EO/PO/AGE)), was reacted with linear mono-functional hydride-terminated polydimethylsiloxane (PDMS-SiH) to obtain PDMS-grafted-polyether (PDMS-g-P(EO/PO/AGE)) by hydrosilylation. Three polyelectrolytes were prepared based on PDMS-g-P(EO/PO/AGE). Best result was obtained when 8wt% of PDMS was introduced onto polyether. Cyclic voltammetry measurement of the PDMS-g-P(EO/PO/AGE polyelectrolytes showed improvement of oxidative stability.

“…By adding a certain substance to form a composite phase, and then controlling the proportion and distribution of the composite phase, new molecular structures and ion transport channels can be generated, which can improve the electrochemical performance of the SSEs (Zhang et al, 2018;Yu and Manthiram, 2021). So researchers have a great research interest in this new type of composite PSSEs (CPSSEs) (Bao et al, 2018;Li et al, 2020;Feng et al, 2021). Among many polymer systems, PEO-based is considered to be the most commonly used polymer substrate.…”

As a high-efficiency energy storage and conversion device, lithium-ion batteries have high energy density, and have received widespread attention due to their good cycle performance and high reliability. However, currently commercial lithium batteries usually use organic solutions containing various lithium salts as liquid electrolytes. In practical applications, liquid electrolytes have many shortcomings and shortcomings, such as poor chemical stability, flammability, and explosion. Therefore, the liquid electrolyte has a great safety hazard. The use of solid electrolyte ensures the safety of lithium-ion batteries, and has the advantages of high energy density, good cycle performance, long life, and wide electrochemical window, making the battery safer and more durable, with higher energy density and simple battery Structural design. Solid electrolytes mainly include inorganic solid electrolytes and organic polymer solid electrolytes. Although both inorganic solid electrolytes and polymer solid electrolytes have their own advantages, as far as the existing research work is concerned, whether it is an inorganic system or a polymer system, a single-system solid electrolyte can never achieve the full performance of an ideal solid electrolyte. The composite solid electrolyte composed of active or passive inorganic filler and polymer matrix is considered as a promising candidate electrolyte for all-solid-state lithium batteries. Among many polymer systems, PEO-based is considered to be the most ideal polymer substrate. In this review article, we first introduced the structure, properties, and preparation methods of PEO-based polymer electrolytes. Furthermore, the researches related to the modification of PEO-based polymer solid electrolytes in recent years are summarized. The contribution of polymer structural modification and the introduction of additives to the ionic conductivity, electrochemical stability and mechanical properties of PEO-based solid electrolytes is described. Examples of different composite solid electrolyte design concepts were extensively discussed, such as inorganic inert nanoparticles/PEO, oxide/PEO, and sulfide/PEO. Finally, the future development direction of composite solid electrolytes was prospected.

“…[ 38,39 ] However, the low oxidation potential of PEO (0–3.13 V) limits its practical application to solid‐state batteries. [ 38,40–43 ] Compared with PEO, polyacrylonitrile (PAN) has good thermal stability and mechanical properties. [ 44 ] In addition, the oxidation‐resistant PAN can accompany well with high‐potential cathode materials.…”

such as leakage, corrosion, swelling, and flammability. [3,4] Therefore, developing non-flammable solid electrolytes to replace traditional organic electrolytes has become the focus of this field. [1,2,5] Meanwhile, lithium metal, with the lowest potential (−3.04 V vs standard hydrogen electrode) and high theoretical capacity (3860 mA h g −1 ), has the potential as anodes for solid-state batteries and greatly improves the energy density. [6][7][8] Solid electrolytes, regarded as the most important core of solid-state batteries, could be roughly divided into three categories: inorganic solid electrolytes (ISEs), solid polymer electrolytes (SPEs), and composite polymer electrolytes (CPEs). [5,[9][10][11] ISEs exhibit high ionic conductivity and a wide electrochemical stability window, while their rigidity restricts close contact with electrodes, which leads to interface problems between ISEs and electrodes. [12][13][14] SPEs, based on Li + immigration in polymers, have considerable advantages over ISEs, such as low cost, easy preparation, high flexibility, and especially good ability to form closer contact with electrodes. However, the ionic conductivity of SPEs is quite low at room temperature. [11,15] Meanwhile, the low ionic transference number of SPEs (< 0.4) is supposed to be the positive incentive of dendrite growth. [16][17][18] At present, researchers improve the ionic conductivity mostly by increasing the proportion of amorphous regions, such as cross-linking, forming copolymers, and adding plasticizers. [19][20][21][22] As ISEs and SPEs mentioned above have different advantages and disadvantages, CPEs could combine the superior properties of inorganic ceramics and polymer matrixes, and not only improve the mechanical properties and ionic conductivity at room temperature over SPEs, but also enhance the interface contact over ISEs. [23][24][25][26][27][28] Therefore, CPEs have been attracting more research interest.CPEs are solid conductors consisting of inorganic fillers dispersed in solid polymer hosts. Inorganic fillers could be generally divided into two kinds, non-lithium conductors (such as TiO 2 and SiO 2 ) and lithium-ion conductors (such as garnet-type Li 7 La 3 Zr 2 O 12 (LLZO), perovskite-type Li 3x La 2/3-x TiO 3 (LLTO), NASICON-type Li 1+x Al x Ti 2-x (PO 4 ) 3 (LATP), and sulfide Li 10 GeP 2 S 12 (LGPS)). [27,[29][30][31][32][33][34][35][36][37] Generally, compared with nonlithium-ion conductors, lithium-ion conductors could provide more lithium-ion transmission channels and thus improve the ionic conductivity. [11,24] Among them, LLZO, LLTO, LATP, and LGPS are four representative well-studied solid electrolytes.
