Sustainable
Recyclable
- Battery stacks can be refurbished and repurposed
- Components are easily separated and recycled
- Chemistry is benign and does not create new compounds
- Stack materials are non-toxic
- Majority of catholyte chemicals are recoverable and reusable
Easily Sourced in North America
- Sodium and sulfur chemistry based on readily available commodity chemicals with large global supplies
- No rare earth minerals required
- All materials available locally in North America
- Sodium is the 6th most abundant element, sulfur is the 16th
Safe
- Power module enclosure is inert and free of moisture
- Oxygen-free environment eliminates possibility of fire.
- Sodium fully contained within power module
- No possibility of reaction between sodium and oxygen or water.
- Safe shutdown condition
- Sodium solidifies at room temperature and can be safely handled with appropriate precautions.
- Fail-safe Redundancy
- In the event of a separator breakage or crack, the battery simply shuts down with no unsafe outcome.
