Solid-state lithium-sulfur batteries promise high energy density, long-term performance, and enhanced safety, but face challenges with interfacial issues due to poor solid–solid contact. Here, the authors review the benefits and challenges of in situ polymerization, discussing its potential to enhance electrode-electrolyte integration and improve battery performance, and proposing future prospects for multifunctional polymer solid-state electrolytes.
