NCM811-Sulfide Electrolyte Interfacial Degradation Mechanisms and Regulation Strategies in All-Solid-State Lithium Battery.

ABSTRACT: The all-solid-state lithium battery (ASSLB) with LiNi_0.8Co_0.1Mn_0.1O₂ (NCM811) cathode and sulfide solid-state electrolyte (SSE) represents a transformative technology, offering enhanced safety and high energy density through the complete elimination of flammable liquid electrolyte and enabling the lithium metal anode. However, its commercialization is fundamentally limited by complex instabilities at the NCM811/sulfide SSE interface, which trigger coupled mechanical, chemical, and electrochemical degradation. The solid/solid interface creates complex dynamic feedback loops: mechanical stress from anisotropic volume changes accelerates interfacial chemical reactions; chemical degradation progressively alters electrochemical behavior; and continuou
