All-solid-state batteries have attracted widespread attention due to their potential for high specific energy and safety, but they struggle to operate stably under low pressure. Here, the authors reveal that fluorine atoms can spontaneously form stable bulk and interfacial structures through rapid diffusion kinetics, thereby improving the ability of all-solid-state batteries to operate stably under low pressure.
