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:

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 Horizon 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

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 Corona Advanced Lead Acid Battery

Lead acid is a low cost power storage technology. Traditionally at full depth of discharge, however, its cycle life is too short to be economically viable for many applications. The Eos Corona lead acid system resolves this cycle life and depth of discharge limitation, while maintaining the low cost per kW of traditional lead acid batteries. Eos’ lead acid system benefits include:

Long-life: 10x longer useful life than existing lead-acid batteries; extension from 500 to 5,000 cycles at full depth of discharge
Proprietary Eos technology: Designed to prevent the deterioration of the anode, extending life
Electric vehicle applications: In combination with Eos zinc-air battery for range, lighter weight for comparable power and energy makes Eos Aurora suitable for powering electric vehicles
Increased energy delivery: for 33 Amp-hour car battery, would increase energy delivery from 0.4 kWh to 0.8 kWh
Increased energy storage and access, and higher gravimetric energy density
Low cost: Same low cost per kW and a lower cost per kWh compared to lead acid SLI batteries
Status: Initial testing complete; must complete design and build full size prototype

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

Eos Electric Vehicle Battery: Eos Aurora 17 | 100 zinc-air battery (17kW, 100kWh) for range +
Eos Corona lead-acid battery for power/acceleration

175 peak HP
>340 mile driving range, competitive with ICE vehicle
Same cost as ICE vehicle without government subsidies
$0.02/mile fuel cost vs. $0.20/mile for gasoline
By using the Eos Vista zinc-air flow battery, the EV becomes refuelable (3 mins) in addition to rechargeable

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
