Stellantis Backs Sodium-Ion Batteries as Cheaper, Safer EV Alternative
Sodium-ion batteries, a cheaper and more sustainable alternative to lithium-ion, are gaining traction. Stellantis Ventures has invested in Tiamat, a French startup leading the way in this technology.
Tiamat's sodium-ion batteries offer numerous advantages. They use aluminum cathodes, reducing production costs. Moreover, they maintain 80% capacity after over 1,000 charge-discharge cycles, demonstrating impressive longevity.
Automakers like Stellantis are exploring new EV technologies to secure supply chains and meet federal regulations on critical mineral sourcing. Stellantis, aiming for carbon net zero by 2038, sees potential in sodium-ion batteries. These batteries also boast greater power density than conventional EV batteries, providing better performance.
Tiamat's batteries charge swiftly, in as little as five minutes, but their lifespan is shorter than lithium-ion counterparts. However, sodium is more abundant and safer to transport than lithium, making sodium-ion batteries a promising alternative.
Stellantis Ventures' investment in Tiamat signals a significant step towards wider adoption of sodium-ion batteries. These batteries, while still in development, offer lower costs, faster charging, and reduced dependence on critical minerals. As automakers seek sustainable solutions, sodium-ion batteries emerge as a viable option.
