Description This prior-art / structural admissibility analysis establishes intrinsic electrolyte–interphase stability as a necessary condition for electrochemical energy storage systems claiming long-term functionality, cycling stability, or industrial deployability. The document is strictly non-constructive and discloses no specific electrolyte compositions, salts, solvents, additives, electrode materials, coatings, separators, fabrication protocols, or operating conditions. Instead, it formalizes invariant boundary conditions under which electrolyte identity and interphase formation must arise from intrinsic chemical compatibility rather than from continuous sacrificial decomposition, additive-driven rebuilding, compensatory degradation, or progressive compositional drift. The condition constrains patentability at the level of enablement/sufficiency, inventive step, and industrial applicability, and applies uniformly across lithium-ion, sodium-ion, solid-state, multivalent, redox-flow, hybrid, and post-lithium electrochemical storage systems.
