Clarios, Altris, and InoBat Advance Sodium-Ion Technology Toward Industrialization
Clarios, Altris, and InoBat report significant progress in sodium-ion battery development, with successful customer evaluations and cold-cranking performance down to –40°C validating the transition to pilot-scale production.
Clarios, a specialist in advanced low-voltage battery solutions, along with Swedish sodium-ion innovator Altris and European battery manufacturer InoBat, announced on September 14, 2026, a new phase of progress in developing sodium-ion battery technology. The companies stated that successful customer evaluations and cold-cranking performance validated down to –40°C support the transition from validation to pilot-scale and small-series production.
This advancement aims to bring sodium-ion batteries closer to industrialization for low-voltage and high-power applications. The collaboration focuses on creating a more cost-effective and sustainable alternative to traditional lead-acid batteries, particularly for automotive uses where cold-weather performance is critical.
The partnership leverages Clarios's expertise in battery solutions, Altris's specialized sodium-ion technology, and InoBat's manufacturing capabilities in Europe. The goal is to accelerate the commercial viability and adoption of this next-generation battery chemistry.
Further development and scaling efforts are expected to focus on optimizing production processes and meeting market demand for reliable, high-performance batteries that can operate effectively in extreme temperatures.
