The Tech

We’re not tweaking yesterday’s battery—we’re building a fundamentally better one. ION was founded by experts across materials science, manufacturing, defense, and energy to bring solid-state batteries out of the lab and into the market. U.S.-engineered and designed for scalable production, our technology is powering the future—on Earth and beyond.

High Energy Density

Why? Higher energy density batteries can store more energy in a smaller, lighter package.

ION’s Solution:

    • Utilizes lithium-metal instead of graphite anodes for higher energy density
    • Ability to accommodate existing and future cathode technologies

    Cycle Life

    Why? Allows for higher capacity cells even after long-term use in demanding applications

    ION’s Solution:

      • Demonstrated benchmark performance
        >1,000 Cycles commercially relevant footprint
        >2,000 Cycles R&D footprint
      • Uniquely able to maintain performance in a wider temperature operating range

      Charge Time

      Why? Encourages customer adoption of electrified products

      ION’s Solution:

        • Achieved ARPA-E and DOE VTO Fast-Charge goals
        • Demonstrated 8-minute fast charge at 60°C where Li-ion cannot safely operate

        No Expansion

        Why? Allows for thinner end-product form factor, with substantially easier integration

        ION’s Solution:

          • No volume change in ION’s cells eliminates need for complicated pack designs

          Ease of Product Integration

          Why? Remove barriers of entry for customer adoption of advanced battery technologies

          ION’s Solution:

            • Platform provides simple and cost-effective manufacturing at scale – reduced pack level design overhead (no compression, no swell allowance, reduced thermal management, etc.)

            Supply Chain Security and Sustainability

            Why? Focus on regionalizing supply chains for reliability and sustainability

            ION’s Solution:

              • Strategic, local partnerships with industry leaders
              • Reduced material needs – no graphite, and ability to design without nickel and cobalt
              • Ability to accommodate existing and future cathode technologies

              Safety

              Why? Safety concerns of high flammability for traditional, unstable solvent electrolytes

              ION’s Solution:

                • Ceramic solid-state separator is nonflammable

                High Energy Density
