Altris AB x Tiamat Comparison: Sodion Energy

Sodion Energy is the most strategically positioned sodium-ion startup for India's two-wheeler market, which sells 20 million units annually at prices below $2,000. Its oxide-based cells deliver 120 to 140 Wh/kg at the pack level, outperforming the average lithium-ion pack in thermal tolerance for tropical conditions. The company's cell-to-pack design reduces weight and cost by eliminating modules, making it cheaper than rival Altris’s modular approach for urban ranges of 80 to 150 km. Pilloted at 100 MWh capacity in Bengaluru, Sodion benefits from India's PLI incentives and pilot agreements with three OEMs, while Tiamat's European focus limits its access to this cost-sensitive market.
