N-rich inorganic solid electrolyte interphase (SEI), effectively suppressing parasitic reactions and dendrite growth. As a result, the Li||P-MPN||Li symmetric cell exhibits stable cycling for over 2300 h, and full cells paired with diverse cathodes (including NCM811, LCO, and LFP) exhibit outstanding cycling stability under high cathode loading and even at -20°C. This work establishes a molecular design strategy for in situ polyurea electrolytes and deepens the understanding of solvation/interphase regulation in high-performance and safe lithium metal batteries.
