“…This may also shed some light on increasing the conductivities of solid polymer electrolytes (SPEs) in ambient temperature region by utilizing super-delocalized anions, as it has proved that extending the conjugate structure of negative charge distribution in imide anions is an effective strategy to enhance the conductivity of SPEs [63,64].…”

“…As a consequence, the electrostatic interaction between the cations and the anion-containing substance becomes relatively weak, resulting in high mobility of lithium ions in the electrolyte material. Indeed, the reported values of ion transference numbers derived from electrochemical measurements for single ion conducting electrolyte materials, such as lithiated Nafion [28,32,33], lithium tartaric acid borate [11], LiPAAOB [9], Li[PSTFSI-co-MPEGA] [21] and P(STFSILi)-b-PEO-b-P(STFSILi) [8], are substantially higher than the values of dual-ion based electrolytes [3e6]. Recently, we have also reported successful syntheses of a series of single ion conducting polymeric electrolytes based on the sp 3 configuration of boron [34e36] and bis(sulfonyl)imide [37e40].…”

“…When blended with PEO (molecular weight, M w = 5 × 10 6 ), there existed a high ionic conductivity of 10 −4 S cm −1 at 60 °C but only 7.6 × 10 −6 S cm −1 at 25 °C. [70] LIBs equipped with this single lithium-ion conducting GPEs are meaningful towards related applications operated at relatively high temperatures. However, the strong dependence of the performance on high temperature also severely limited their applications in portable and wearable electronics and electric vehicles which commonly work at near ambient temperatures.…”

storage devices with adjustable shapes and high flexibility, which is promising for the burgeoning portable and wearable electronics. [7][8][9] Furthermore, the flexibility and elasticity of GPEs are also prone to tolerate the volume change of electrode materials and the dendrites of lithium metal during charge and discharge processes. [10][11][12][13] As a consequence, GPEs have become one of the most desirable alternatives among various electrolytes for the electrochemical energy storage devices, and significant progress has been made in lithium-ion batteries (LIBs), supercapacitors (SCs), lithium-oxygen (Li-O 2 ) batteries as well as the other kinds of electrochemical energy storage devices, such as sodium-ion batteries, lithium-sulfur batteries, fuel cells, and zinc-air batteries. [14][15][16] In order to meet the requirements of wearable devices for flexibility and deformability, more special GPEs with tough, [17] stretchable, [18] and compressible [19] functionalities have been also developed.Typically, a polymeric framework is adopted in GPEs as host material, providing high mechanical integrity. Several criteria for a good polymer host lie in: [20][21][22] (i) fast segmental motion of polymer chain; (ii) special groups promoting the dissolution of salts; (iii) low glass transition temperature (T g ); (iv) high molecular weight; (v) wide electrochemical window; (vi) high degradation temperature. Within the framework, the salts in the GPEs serve as the sources of the charge carriers, which are generally required to have large anions and low dissociation energy for easier dissociating-induced free/mobile ions. According to the types of electrolytes, there are four categories of GPEs based on proton, [23] alkaline, [24] conducting salts, and ionic liquids (ILs). [25] The criteria for an appropriate electrolyte include: [26][27][28] (i) good dissociation without forming ion pairs or ion aggregation; (ii) high thermal, chemical, and electrochemical stability; (iii) high ionic conductivity. In order to dissolve both the polymer hosts and electrolytic salts, the organic/ aqueous solvents are introduced to provide the medium for ionic conduction. A good solvent should simultaneously have high dielectric constant (ɛ > 15), donor number for more dissociation of ion and chemical and electrochemical stability. Organic solvents normally include ethylene carbonate (EC), propylene carbonate (PC), diethyl carbonate (DEC), dimethyl carbonate (DMC), dimethyl formamide (DMF), dimethyl sulphoxide, ethyl methyl carbonate, and tetrahydrofuran.To prepare a high-performance GPE, it is essential to select the species of host polymer, solvent, and electrolytic salt, and then blend them by solution or melt processes, such as casting With the booming development of flexible and wearable electronics, their safety issues and operation stabilities have attracted worldwide attentions. Compared with traditional liquid electrolytes, gel polymer electrolytes (GPEs) are preferred due to their higher safety and adaptability to the design of ...
