Solid-State / Solid-Liquid Electrolyte Li-Ion Battery Innovation & Patent Review

  • Company Chapter – Ilika – United Kingdom

    Version: 2026-06-26, for paid subscribers
  • Technology Assessment: Ilika advances two distinct solid-state platforms in parallel – large-format cells for electric vehicles and defence, and thin-film microbatteries for medical implants. The chapter examines how a low-temperature garnet densification approach positions against conventional ceramic processing, how near-term microbattery commercialization complements longer-term automotive development, and how public positioning aligns with what the patent portfolio reveals about priorities.
    Product Development Pathway
    (8 R&D Concepts)
    Low-temperature garnet co-sintering anchors the large-format route, addressing the risk that ceramic densification would destroy an electrode's metal collectors and carbon additives; a current-collecting mesh built into the sintered electrode then removes that inactive mass. Further concepts cover thick-electrode transport, the microbattery route's thin-film stack, and interface protection during deposition.
    Potential Synergies to Deliver Well-Rounded Cells for Application
    A single low-temperature sintering window lets the built-in mesh collector, thick-electrode transport network, and garnet separator form in one co-sintered body – targeting high areal capacity with low inactive mass.
