Clarios, a global supplier of advanced battery solutions, and Altris, a Swedish developer and prototype manufacturer of sodium-ion batteries, announced an exclusive Joint Development Agreement (JDA) for low voltage mobility applications.
Under the new JDA, Altris will focus on developing the sodium ion cell technology for low-voltage applications, while Clarios will leverage its expertise in Battery Management Systems (BMS), software, and system integration to design the battery system. This development agreement enhances a collaboration agreement initiated earlier this year, which set in motion the creation of a detailed production plan for low-voltage vehicle batteries utilizing sodium-ion cells. This initiative is particularly timely, aligning with a pivotal moment in the global automotive industry's transformation.
Every vehicle, including hybrid and fully electric models, requires a reliable low-voltage energy source to power essential systems and functions. As the complexity of vehicles increases, the low-voltage network must adapt to support a growing array of software-based functions, including steer-by-wire, brake-by-wire, autonomous technologies, and enhanced in-cabin experiences. Sodium-ion (Na-ion) batteries are well suited to meet these increased power demand and at the same time are inherently sustainable and easy to recycle. Na-ion technology offers an energy density on par with LFP battery technologies and is particularly sustainable thanks to its environmentally friendly and easily recyclable materials. The materials used to produce Na-ion cells – salt, wood, iron and air – are abundant and free from conflict minerals and toxic elements. Developing Na-ion batteries for vehicles would represent an important advancement in automotive battery technology and advance the circularity goals of the automotive industry.
