“…Notably, lithium salt anions are anchored by functional groups on their polymer skeleton, which facilitate lithium ion transfers. Jeong et al [48] prepared cross-linked single-ion conducting gel polymer electrolytes (CSGE#s) through in situ polymerization using methacrylate graphene oxide (MGO), lithium 1-[3-(methacryloyloxy)propylsulfonyl]-1-(trifluoromethane sulfonyl)imide (LiMTFSI), and PVDF-HPF (Figure 2a). Compared with Celgard with an ordinary LE, CSGE1.0 can inhibit the formation of lithium dendrites well (Figure 2b).…”

Lithium metal batteries (LMBs) are a dazzling star in electrochemical energy storage thanks to their high energy density and low redox potential. However, LMBs have a deadly lithium dendrite problem. Among the various methods for inhibiting lithium dendrites, gel polymer electrolytes (GPEs) possess the advantages of good interfacial compatibility, similar ionic conductivity to liquid electrolytes, and better interfacial tension. In recent years, there have been many reviews of GPEs, but few papers discussed the relationship between GPEs and solid electrolyte interfaces (SEIs). In this review, the mechanisms and advantages of GPEs in inhibiting lithium dendrites are first reviewed. Then, the relationship between GPEs and SEIs is examined. In addition, the effects of GPE preparation methods, plasticizer selections, polymer substrates, and additives on the SEI layer are summarized. Finally, the challenges of using GPEs and SEIs in dendrite suppression are listed and a perspective on GPEs and SEIs is considered.

In situ polymerization technology is expected to empower the next generation high specific energy lithium batteries with high safety and excellent cycling performance. Nevertheless, the large‐scale commercial applications of most reported in situ polymer electrolytes are still full of challenges. Owing to the severe parasitic reactions caused by residual monomers, additional initiators and oligomers, lithium batteries using in situ polymer electrolytes often demonstrate limited specific capacity, poor cycling performance, and insufficient rate capability. However, this issue has not received adequate attention in previous reports. Furthermore, the design and evaluation of in situ polymer electrolytes still lack effective guidance and unified standards. Herein, the development history of in situ polymer electrolytes are systematically reviewed and critically disclose the great challenges. Then, from the aspects of monomers, initiators, separators, manufacturing technologies, safety and cycle life evaluation, unprecedentedly a new paradigm is provided for upgrading the in situ polymerization technology inside lithium batteries. It is hoped the novel paradigm will prompt much more insightful studies, expediting the commercialization of in situ polymerization technology in lithium batteries.
