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.

Proven Power: Real-World Sodium-Ion Battery Performance

Engineered for extreme cold and built for scale, Clarios’ new power sodium-ion cell technology delivers high current output, low-temperature reliability, and competitive energy density. Derived from abundant, conflict-free materials such as salt, wood, iron, and air, sodium-ion seamlessly complements lead-acid and lithium-ion options to give OEMs a high-performance, cost-effective, and highly recyclable solution for a sustainable future.

Sodium-Ion Cold-Cranking Performance

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.

Hanover, Glendale, February 20, 2025 – Clarios, a global leader in advanced energy storage solutions, has achieved this milestone with the support of its global network. The company manufactures Lithium Titanate Oxide (LTO) cells in the USA and assembles systems in Europe, close to its customers. On January 31, 2025, Clarios produced its one millionth lithium-ion 12 volt battery, underscoring its role as an innovator in low voltage energy storage technologies. These batteries are critical for vehicles with high electrification, including internal combustion (IC), hybrids, plug-in hybrids (PHEV), and electric vehicles (EV).

With the production of 6 million 10Ah LTO Prismatic Power Cells and 1 million 12V Lithium-Ion batteries, Clarios has marked a significant milestone in its transition from a pure Lead Acid battery manufacturer to a chemistry-agnostic Energy Systems supplier. All LTO cells are produced in-house at the Clarios plant in Meadowbrook, Michigan, US. The production line for lithium-ion low-voltage batteries was launched in 2020 in Hanover, Germany. Since then, Clarios has continuously invested in advancing its technology and production capacities to meet the growing demand for cutting-edge battery systems.

The Clarios Hanover lithium-ion assembly site plays a central role in Clarios' global production strategy. With state-of-the-art technology and a dedicated workforce, innovative energy storage solutions are developed here for deployment worldwide. The production line is a pioneer in manufacturing low-voltage battery systems and serves as a blueprint for other locations.

The team in Hanover is characterized by outstanding teamwork and continuous development. Particularly noteworthy is the integration of new expertise in engineering and software development. The acquisition of the Paragon Power business in 2023 allowed Clarios to successfully incorporate additional knowledge and experienced employees into the existing team. This combination of experience and innovation is a key success factor.

Currently, Clarios produces 12 Volt high-performance lithium-ion low-voltage batteries for modern vehicles and is working on future-oriented technologies such as sodium-ion batteries, supercapacitor solutions, and dual-voltage systems. These products highlight Clarios' commitment to sustainable and efficient future mobility.

“Our teams in Hannover, Germany, Meadowbrook Holland Michigan; US, and worldwide set new standards every day. Their commitment and innovative spirit make Clarios what it is today,” emphasizes David Patel, Vice President Energy Systems Clarios.

With its one-millionth lithium-ion low-voltage battery, Clarios is well-prepared to tackle future challenges in the mobility sector. The company plans further investments in research and development as well as the expansion of its product portfolio to deliver sustainable and high-performance solutions.
