“…Figure 3b shows the electrochemical stability window (ESW) of composite solid electrolyte tested by linear sweep voltammetry (LSV). From previous studies, 18,24 it can be found that the polymerized PDOL has a higher antioxidant decomposition ability than pure liquid DOL, so its ESW value is increased. And after the addition of g-C 3 N 4 particles, its ESW is further increased because g-C 3 N 4 particles have extremely high chemical stability, so that the prepared composite film can match the requirements of high voltage positive electrodes.…”

“…Therefore, the use of solid electrolyte has become a trend to solve the above problems. [8][9][10] Compared with the common polymers (PVDF, 11 PEO 12 ) and sulfide electrolyte, 13 pomegranate type solid electrolyte (LLZO), 14 NASICON type Li + ionic conductor (LAGP, LATP), 15 polymer and ceramic composite solid electrolyte, 16 etc, the poly(1,3dioxolane) (PDOL) formed by the polymerization of conventional liquid 1,3-dioxolane (DOL) with LiPF 6 , not only has higher ionic conductivity, 17,18 but also has better interface compatibility with lithium anode, 19,20 which can effectively inhibit the growth of lithium dendrites, thereby protecting the lithium anode and improving the cycle stability of the battery. [21][22][23] And this polymer electrolyte can be combined with inorganic fillers to improve the ionic conductivity of solid electrolyte, such as adding yttrium stabilized zirconia (YSZ), 24 Li 1.5 Al 0.5 Ge 1.5 (PO 4 ) 3 (LAGP) 25 or graphene oxide material (GO), 26,27 etc.…”

The poor interfacial compatibility between solid electrolyte and lithium metal anode is one of the main obstacles to the development of solid lithium metal battery. Herein, the poly (1,3-dioxolane) (PDOL) polymer is combined with g-C3N4 powders to form a flexible and dense composite solid electrolyte film, which not only possesses high ionic conductivity of 3.7 × 10−4 S·cm−1, high ion migration number up to 0.86, and wide electrochemical stability window of 5.0 V, but also is helpful for inhibiting the growth of lithium dendrites to improve the interfacial stability of the lithium anode and close contact with cathode. The prepared S/g-C3N4-PDOL/Li battery exhibits good rate and cycle performances with a capacity of 550 mAh g−1 at 1 C, and 1150 mAh g−1 at 0.1 C with a capacity retention rate of 83% after 100 cycles. The dense Li3N layer generated by the reaction between g-C3N4 and Li gives g-C3N4/PDOL composite electrolyte a high inhibition ability of lithium dendrites. This composite solid electrolyte film with an interface modification function has good practical application prospects in lithium-sulfur batteries.

“…1,2-dimethoxyethane (DME) has been extensively used as a plasticizer for PDOL electrolytes and has shown favorable balance performance [ 58 , 59 , 63 , 67 , 77 , 85 , 121 ]. Maoxiang Jing [ 122 ] investigated in detail the effect of DME addition on PDOL polymerization conversion and found that with increasing DME content, the polymerization conversion of DOL decreased. The Arrhenius equation was employed by the author to fit and compute the activation energy at varying ratios, based on the ion conductivity measurements at different temperatures.…”

Polymer solid-state lithium batteries (SSLB) are regarded as a promising energy storage technology to meet growing demand due to their high energy density and safety. Ion conductivity, interface stability and battery assembly process are still the main challenges to hurdle the commercialization of SSLB. As the main component of SSLB, poly(1,3-dioxolane) (PDOL)-based solid polymer electrolytes polymerized in-situ are becoming a promising candidate solid electrolyte, for their high ion conductivity at room temperature, good battery electrochemical performances, and simple assembly process. This review analyzes opportunities and challenges of PDOL electrolytes toward practical application for polymer SSLB. The focuses include exploring the polymerization mechanism of DOL, the performance of PDOL composite electrolytes, and the application of PDOL. Furthermore, we provide a perspective on future research directions that need to be emphasized for commercialization of PDOL-based electrolytes in SSLB. The exploration of these schemes facilitates a comprehensive and profound understanding of PDOL-based polymer electrolyte and provides new research ideas to boost them toward practical application in solid-state batteries.

“…The utilization of GPE in both S|Li and LiFePO 4 |Li batteries delivered excellent cycling performance for 1000 and 700 cycles, respectively (Figure 2C). In addition to DME, [33][34][35][36] carbonates such as ethylene carbonate (EC), [37] fluoroethylene carbonate (FEC), [38][39][40] and methyl ethyl carbonate [41] have also been studied as cosolvents for DOL in PDOL-based GPEs. Compared with ether solvents, carbonates possess stable thermodynamic properties, high dielectric constant, and low volatility which enable high safety and better anode reversibility.…”

The application of lithium-based batteries is challenged by the safety issues of leakage and flammability of liquid electrolytes. Polymer electrolytes (PEs) can address issues to promote the practical use of lithium metal batteries.However, the traditional preparation of PEs such as the solution-casting method requires a complicated preparation process, especially resulting in side solvents evaporation issues. The large thickness of traditional PEs reduces the energy density of the battery and increases the transport bottlenecks of lithium-ion. Meanwhile, it is difficult to fill the voids of electrodes to achieve good contact between electrolyte and electrode. In situ polymerization appears as a facile method to prepare PEs possessing excellent interfacial compatibility with electrodes. Thus, thin and uniform electrolytes can be obtained. The interfacial impedance can be reduced, and the lithium-ion transport throughput at the interface can be increased. The typical in situ polymerization process is to implant a precursor solution containing monomers into the cell and then in situ solidify the precursor under specific initiating conditions, and has been widely applied for the preparation of PEs and battery assembly. In this review, we focus on the preparation and application of in situ polymerization method in gel polymer electrolytes, solid polymer electrolytes, and composite polymer electrolytes, in which different kinds of monomers and reactions for in situ polymerization are discussed. In addition, the various compositions and structures of inorganic fillers, and their effects on the electrochemical properties are summarized. Finally, challenges and perspectives for the practical application of in situ polymerization methods in solidstate lithium-based batteries are reviewed.
