💡 Novelty & Significance:
This work introduces dual-functional microcapsules that integrate fire suppression into solid polymer electrolytes. Upon heating, they release a fire-extinguishing agent and form a protective char layer, while maintaining high ionic conductivity (0.64 mS cm⁻¹) and a 4.6 V stability window. This offers a viable strategy for safer lithium metal batteries with thermally triggered fire suppression.
