“…PEDOT is a polythiophene derivative with high conductivity, excellent chemical stability and flexibility, which can inhibit the shuttle of polysulfides and accelerate the electron transfer speed, further improving the energy density and cycle stability of LSBs [ 70 , 71 , 72 ]. Within separators modified by PEDOT, the electrochemical performance of LSBs can be significantly improved [ 51 , 73 , 74 , 75 ].…”

Lithium–sulfur batteries (LSBs) are considered a promising candidate for next-generation energy storage devices due to the advantages of high theoretical specific capacity, abundant resources and being environmentally friendly. However, the severe shuttle effect of polysulfides causes the low utilization of active substances and rapid capacity fading, thus seriously limiting their practical application. The introduction of conductive polymer-based interlayers between cathodes and separators is considered to be an effective method to solve this problem because they can largely confine, anchor and convert the soluble polysulfides. In this review, the recent progress of conductive polymer-based interlayers used in LSBs is summarized, including free-standing conductive polymer-based interlayers, conductive polymer-based interlayer modified separators and conductive polymer-based interlayer modified sulfur electrodes. Furthermore, some suggestions on rational design and preparation of conductive polymer-based interlayers are put forward to highlight the future development of LSBs.

“…Introducing a PEDOT modified layer onto the separator by some physical/chemical methods, such as coating, extraction filtration, and in situ growth, can also effectively improve the performance of Li-S batteries. [78,[208][209][210] Yi and co-workers [211] adopted a lightweight dualfunctional modified separator coated with carbon black(CB)/PEDOT: PSS, aiming at serving as a co-current collector to remarkably improve the sulfur utilization in Li-S batteries (Figure 16b). The presence of PEDOT: PSS effectively inhibited the LiPS diffusion through the separator and promoted the Li + migration by chemical absorption and cation migration acceleration, so the batteries assembled with this separator exhibited a high specific capacity of 1315 mAh g À1 .…”

Lithium–sulfur (Li–S) batteries have attracted increased interest because of the high theoretical energy density, low cost, and environmental friendliness. Conducting polymers (CPs), as one of the most promising materials used in Li–S batteries, can not only facilitate electron transfer and buffer the large volumetric change of sulfur benefiting from their porous structure and excellent flexibility, but also enable stronger physical/chemical adsorption capacity toward polysulfides (LiPSs) when doped with abundant heteroatoms to promote the sulfur redox kinetics and achieve the high sulfur loading. This review firstly introduces the properties of various CPs including structural CPs (polypyrrole (PPy), polyaniline (PANi), polyethylene dioxothiophene [PEDOT]) and compound CPs (polyethylene oxide (PEO), polyvinyl alcohol (PVA) and poly(acrylic acid) [PAA]), and their application potential in Li–S batteries. Furthermore, the research progress of various CPs in different components (cathode, separator, and interlayer) of Li–S batteries is systematically summarized. Finally, the application perspective of the CPs in Li–S batteries as a potential guidance is comprehensively discussed.

“…The initiator plays an important role in the process of in situ polymerization, which directly affects the properties of the electrolyte. In addition to frequently used Al 3+ [58,59] and H + , [32,35,60] BF 3 , [61,62] Sn 2+ , [63,64] Zr 4+ , [65] and Mg 2+ [66] have been developed as multifunctional initiators that not only initiate the in situ polymerization but also improve the performance of batteries. In a recent work reported by Huang's group, [61] tris(pentafluorophenyl) borane (TB) was proven to have the effect of high-efficient flame retardant via generating fluorine radicals which could trap the reactive radicals of H + and OH − , thus realizing a flame-retardant PE (Figure 6C).…”

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.
