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

  • Company Chapter – Blue Current – USA

    Version: 2026-04-14, for paid subscribers
  • This chapter covers Blue Current's solid-state Li-ion battery-related product development efforts and corresponding patent portfolio:
    • Semi-quantitative classification of patent families by Blue Current, revealing exclusive focus on sulfide electrolytes, with 4 identified product development concepts spanning oxide-substituted argyrodite chemistry, composite separator architecture, polymer binder engineering, and scalable multilayer cell assembly.
    • Technology assessment including latest-available benchmarking data (cycling, energy density, safety testing), unique-capability positioning relative to peer sulfide-electrolyte developers, an underlying scientific hypothesis with cross-concept interdependencies, and a congruency analysis between public technical statements and the patent portfolio.
    • Scale-up risk factors and commercialization angle, covering separator-thinning challenges, fabrication-step throughput, chemical-stability constraints, and operating-pressure dependencies; timeline feasibility assessment spanning strategic investor partnerships, pilot-production milestones, and application strategy.
  • Document size: ≈3,200 words, 8 images, 1 adjacent Excel file (list of patent families with AI-based summaries)
