“…到目前为止, 尽管诸多研究已经证实原位聚合是制备兼具高离子电导率和优异界面相容性固态聚合物电解质的十分有效的方法, 但目前大多数研究仍然聚焦在自由基聚合原位固态化技术方面 [16] . 一般来讲, 自由基聚合通常会引入额外引发剂如偶氮二异丁腈(AIBN)等, AIBN 会与锂金属发生副反应进而对锂负极产生不利影响进而恶化电池性能 [17] ; 与此同时, 自由基聚合普遍需要高温等较为苛刻的外界条件, 难以在温和的外部条件下实现制备 [18] . 相对比而言, 离子聚合原位固态化构建聚合物电解质则只需要温和的反应条件(如室温), 且引发剂可以是锂盐或锂金属等而无需引入额外引发剂, 从而有效避免引入杂质与电极发生副反应等诸多不利影响 [19][20] 1 Performance of solid polymer electrolytes prepared via in-situ cationic polymerization for high-safety lithium batteries 参考文献阳离子聚合构建的固态聚合物电解质的成分组成电化学性能充放电电压区间和测试温度电池性能 (包含对比样) [22] 实验样: DOL＋2 mol/L LiTFSI＋0.…”

Lithium-ion batteries, widely used in many aspects of the national economy such as electric vehicles, mobile intelligent devices and large-scale energy storage, have gradually entered special applications area including deep sea, deep space, deep ground and individual combat equipment. However, lithium batteries using traditional carbonate liquid electrolytes often suffer from potential safety risk such as electrolyte leakage, flammability and explosion, so it is urgent to develop a new generation of high-safety solid electrolytes. Among them, solid polymer electrolytes have attracted great attention because of their superior mechanical flexibility and compatibility with the main production processes of lithium battery. In terms of preparation process, solid polymer electrolytes prepared via solution-casting often easily lead to high interfacial resistance and then deteriorate the battery performance. In contrast, liquid organic precursors used in in-situ polymerization strategy can sufficiently penetrate the positive and negative electrodes to guarantee superior interfacial compatibility and efficient ionic conduction. At present, most of in-situ polymerization strategies are based on free radical thermal polymerization with additional initiators and the need for harsh conditions such as high temperature. Ion polymerization can use lithium salt or lithium metal as an initiator at room temperature, thereby effectively avoiding the introduction of impurities. Up to now, researchers have made considerable research progress in the construction of solid polymer electrolytes by ion-initiated

“…Besides, the widely reported lithium salts, LiTFSI and LiFSI, at present have been only used as additives in the commercial electrolyte because of their high cost. In contrast, GPEs could constraint the large amount of liquid commercial electrolyte into their polymer networks to provide lithium ion transport and good interfacial contact with electrode 15–17 …”

“…In contrast, GPEs could constraint the large amount of liquid commercial electrolyte into their polymer networks to provide lithium ion transport and good interfacial contact with electrode. [15][16][17] High σ and lithium ion transfer number, electrochemical stability, tough mechanical properties, and stable interfacial properties toward lithium metal anode are the main concerns for designing GPEs structures. As widely acknowledged, the ethylene oxide unit is a typical structure studied for the lithium ion transport by inter/intra molecular polymer chain.…”

Synthesizing high‐performance of gel polymer electrolytes (GPEs) with simple methods and common materials has long been a crucial concern for lithium‐ion batteries. Here, the poor mechanical properties of polyethylene oxide (PEO) based GPEs were overcome by introducing strong hydrogen bond between PEO and polyacrylic acid (PAA). Easy‐available PEO/PAA membranes were prepared though hot processing approach without use of organic solvent during all processes. The mechanical properties and crystalline of dry composites could be tuned by the addition content of PAA. After quick absorbing electrolyte in 30 min, the tensile strength and elongation at break of the GPEs composites are ranged from 0.07 to 0.63 MPa, and 525% to 722%. Moreover, the lithium‐ion conductivity and transference number with 30 wt% addition of PAA reach up to 1.66 and 0.58 mS/cm, respectively. After 500 cycling at 0.5 C, the discharge specific capacity and the capacity retention rate are still up to 134.1 mAh/g and 88.7%, respectively. This research proves the great possibility of applying environmentally friendly method, low cost, and high electrochemical performances of PEO/PAA based GPEs in the lithium batteries.

“…Several studies have investigated the ionic conduction of polymer electrolytes [16][17][18] to develop multifunctional energy-producing composites, such as structural batteries. In particular, researchers have utilized poly(ethylene glycol) (PEG)-based materials [19][20][21] and have demonstrated their high conductivity. Several authors [22][23][24] have studied ionic impurities in organic materials, particularly in LCs, using Iwamoto's hopping model [25] to describe their conductivity behavior.…”

The study investigated the effect of the molecular weight of three difunctional poly(propylene glycol) diacrylates on the temperature-dependent ionic conductivity of these monomers and their blends with an eutectic nematic liquid crystal mixture (E7). The results revealed two distinct regions. At low temperatures, ionic conduction can be described by the Vogel–Tamman–Fulcher (VTF) equation, while at high temperatures, the conductivity data follow the prediction of the Arrhenius model. The Arrhenius and VTF parameters and their corresponding activation energies were determined using the least squares method. In addition, a conductivity analysis based on an ionic hopping model is proposed. Estimates of ion concentrations and diffusion constants were calculated. It was found that both the ionic concentration and the diffusion constant decrease with the increase in the molecular weight of the monomers. The static dielectric permittivity decreases in the following order: TPGDA, PPGDA540, and PPGDA900. This can be explained by the higher dipole moment of TPGDA, which is caused by an enhanced volume density of carbonyl groups.
