Eos develops novel, low-cost energy storage solutions for transportation
and other industries. Eos’ proprietary energy storage can be used in electric vehicles (EV) to:
  • Enable EVs to be cost competitive with internal combustion engine (ICE) powered cars — with the same performance and range, but with 1/10th the fuel cost ($0.02/mile)
  • Lengthen driving range to >340 miles
  • Provide a safe, stable, long-life propulsion system

    • Eos Aurora 17 | 100
    Based on Eos’ breakthrough long-life rechargeable zinc-air battery, the Eos Aurora 17 | 100 can be used in EV platforms for range, combined with Eos’ advanced lead acid battery for power.


    • Proprietary technology: first ever long-life rechargeable zinc-air battery
    • 17kW, 100 kWh rechargeable zinc-air battery, sized for electric vehicle market
    • Low cost:
      • - Approximately $12,000 vs $70,000 for equivalent li-ion battery
      - Low-cost manufacturing designed into product
    • Response time: Immediate
    • Non-toxic, non-flammable electrolyte and materials
    • Based on robust, well developed technology: disposable zinc-air batteries, widely used today (e.g. in hearing aids)
    • High energy density: In the same way that gasoline uses oxygen to burn, the Aurora uses oxygen from ambient air as a cathode reactant, allowing the battery to “breathe” and saving space and cost
    • Safe, low cost, locally sourced, readily available materials
      • - Zinc: One of the world’s most plentiful and inexpensive metals, stable, non-toxic, energy dense, locally available
      (US, Canada and Australia are three of top five global zinc producers)
      - Air
      - Electrolyte ingredient also used in popular toothpaste brands
    • Status: Currently scaling up battery prototypes (17kW units) for initial manufacturing in 2012 and delivery of MW scale systems for grid-storage to customers in 2013. This product will be the point of departure for the automotive implementation.
    Eos Vista Zinc-Air Flow Battery
    Eos is also developing a zinc-air flow battery, designed to provide flexible vehicle range and enable immediate refueling in addition to standard recharging.
  • Proprietary zinc-air flow battery based on Eos’ zinc-air technology
  • Flexible vehicle range: Allows decoupling of the power and energy of the battery for more flexible configuration and lower cost per kWh
  • Immediate refueling: As battery discharges, the used electrolyte is stored and replaced, and more zinc is added, allowing for battery operation to continue
  • Status: Early, further design development required

    • Growing Market
    LCM Research estimates that the market for electric vehicle batteries will grow to $16B by 2016 and $33B by 2025… without any consideration for the elasticity of the market should costs come down to the level Eos can achieve.i

    Opportunities for Partnership
    Eos is pursuing strategic partnerships with companies in the automotive industry to jointly develop solutions for electric vehicle applications using Eos’ proprietary battery technologies.

    Strong IP Protection
    Multiple patents issued and pending with over 100 claims covering:
  • Cell configuration and architecture
  • Cathode design, materials and catalysts
  • Electrolyte and additives
  • System configuration and electrolyte system

    Eos’ Mission
    Eos’ mission is to produce the most cost effective energy storage solutions that are not only less expensive than other battery technologies, but less expensive than the most economical alternative used today to provide the same services – an internal combustion engine for vehicle power.
