Clarios sodium-ion batteries

Sodium-ion (Na-ion) batteries offer a sustainable solution for the evolving demands of modern vehicles. Made from abundant materials such as salt, wood, iron, and air, they are inherently easy to recycle and free from conflict minerals and toxic elements. To accelerate the development of this technology, Clarios has partnered with Altris, a leader in sodium-ion cathode material and battery cell technology, to bring advanced Na-ion solutions to the low-voltage automotive market—an essential system for powering critical vehicle functions.

Advancing Energy Innovation with Sodium-Ion

Energy Innovation for Modern Mobility

Sodium-ion (Na-ion) technology delivers energy density on par with lithium iron phosphate (LFP) battery technologies while maintaining strong sustainability credentials.

Sustainable Chemistry, Abundant Resources

Na-ion batteries are produced using salt, wood, iron, and air—free from conflict minerals.

Engineered for System Integration

Na-ion batteries are being developed with up to 60 volts of potential, supporting both new vehicles and aftermarket replacements in multi-battery low-voltage systems.

Optimized Safety and Redundancy

The Clarios low-voltage system architecture ensures critical safety features, system redundancy, and compatibility with evolving vehicle platforms.

Delivering Value for the Road Ahead

Our sodium-ion development efforts are designed to deliver advanced low-voltage battery systems that meet the growing power demands of modern vehicles while supporting sustainability and circularity goals. By combining Clarios’ expertise in low-voltage architectures and system integration with Altris’ leadership in sodium-ion technology, automakers gain access to a chemistry-agnostic portfolio that includes lead-acid, lithium-ion, and sodium-ion solutions. These innovations ensure compatibility with evolving vehicle platforms, enhance system redundancy for critical safety features, and provide sustainable alternatives for future mobility.
