Solid-state / Semi-solid Li-ion Battery Innovation & Patent Review

  • Ilika – United Kingdom (Version: 2026-06-26)



    This chapter reviews the solid-state and semi-solid-state lithium-ion battery patent portfolio of Ilika, a UK developer pursuing two distinct platforms: large-format cells for electric-vehicle and defence applications, and thin-film microbatteries for medical-implant and IoT applications. The full review covers:

    • Technology Assessment – latest identified benchmarking data, unique capabilities, the central leap-of-faith hypotheses, timeline feasibility, scale-up risk factors, and the congruency between public statements and the patent portfolio, analyzed separately for each of the two platforms.
    • Commercial & go-to-market angle – the asset-light licensing model, contract-manufacturing partnership, customer-evaluation pipeline, and programme milestones.
    • General Patent Portfolio Characteristics – the family-level breakdown by development level and the principal patenting focus areas.
    • Key Product Development Concepts – the distinct technical concepts identified for each platform, each mapped to its supporting patent families with direct EPO and Google Patents access links.
    • AI-based Patent Summaries – structured per-family summaries in an accompanying spreadsheet.
  • Document size: ≈7,000 words, 20 images, 1 adjacent Excel file (list of patent families with AI-based summaries)
