    Version: 2026-04-01, minor update: 2026-05-14, for paid subscribers
  • Technology Assessment: BASF positions as a materials supplier rather than a cell maker – a role demanding flexibility across diverse customer cell architectures. The chapter examines how the bilayer electrolyte approach balances oxidative and reductive stability demands, whether cross-compatible interface materials support architecture-agnostic integration, and how the patent portfolio’s scope compares with public positioning.
    Product Development Pathway
    (5 R&D Concepts)
    Bilayer electrolyte architecture pairing a glassy lithium aluminum oxychloride catholyte selected for oxidative stability with a sulfide argyrodite separator handling reductive-side functions, leveraging each electrolyte class’s mechanical and electrochemical strengths. Cation-substituted chlorine-rich argyrodite sulfide electrolyte achieving enhanced ionic conductivity through simultaneous vacancy creation and halide sublattice tuning. Further concepts address high-nickel cathode surface stabilization through gradient doping and island coating, dual ion-and-electron conduction pathways at the cathode/sulfide interface, and self-terminating anode passivation for lithium metal compatibility across multiple electrolyte families.
    Potential Synergies to Deliver Well-Rounded Cells for Application
    Cross-compatible electrolyte, cathode, and anode interface materials converging on a flexible supply portfolio – enabling customers to integrate complementary components across sulfide, halide, and hybrid cell architectures for balanced product launch viability.
