“…18,19,26 The resulting poly-DOL (P-DOL) PEs have demonstrated high ionic conductivity, good Li plating/stripping reversibility, and stable cycling when matched with lowvoltage cathodes of LiFeO 4 (LFP). 18,19,27,28 However, the P-DOL chain decomposes easily at high-voltage which has been confirmed lately (Fig. 1b), exhibiting poor electrochemical performance with high-voltage cathodes (4 V-above class).…”

Solid‐state lithium‐metal batteries constructed by in‐situ solidification of cyclic ether, are considered to be a critical strategy for the next generation of solid‐state batteries with high energy density and safety. However, the poor thermal/electrochemical stability of linear polyethers and severe interfacial reactions limit its further development. Herein, in‐situ ring‐opening hybrid crosslinked polymerization is proposed for organic/inorganic hybrid polymer electrolyte (HCPE) with superior ionic conductivity of 2.22×10−3 S cm−1 at 30°C, ultrahigh Li+ transference number of 0.88, and wide electrochemical stability window of 5.2 V. These allow highly stable lithium stripping/plating cycling for over 1000 h at 1 mA cm−2, which also reveal a well‐defined interfacial stabilization mechanism. Thus HCPE endows assembled solid‐state lithium‐metal batteries with excellent long‐cycle performance over 600 cycles at 2 C (25°C) and superior capacity retention of 92.1%. More importantly, our proposed non‐combustible HCPE opens up a new frontier to promote the practical application of high safety and high energy density solid‐state batteries via in‐situ solidification.This article is protected by copyright.

“…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.
