Sodion Energy, founded in 2020 in Bengaluru, India by Satish Sandilya and Bharat Bhatt, is the most strategically positioned sodium-ion startup for the world's largest two-wheeler market. India sells approximately 20 million two-wheelers annually, and the electrification of this segment — dominated by scooters and motorcycles priced below $2,000 — requires battery packs that are cheaper, safer, and more thermally tolerant than the lithium-ion cells currently used. Sodion's value proposition targets this gap directly. Sodion Energy develops its own sodium-ion cells using oxide-based cathode materials adapted for the tropical temperature ranges prevalent across South and Southeast Asia (-5 to 55 degrees Celsius in typical deployment conditions). The company's cell-to-pack design philosophy integrates cells directly into structural battery packs without modules — a topology that reduces pack weight and cost while improving volumetric efficiency. Energy density is reported at approximately 120 to 140 Wh/kg at the pack level, lower than Chinese peers but sufficient for the 80 to 150 km urban range requirements of the target market. Sodion has raised funding from the Indian Institute of Science (IISc) technology transfer office and multiple Indian impact investors, securing support from the Department of Science and Technology's national mission on transformative mobility. The company has signed pilot agreements with three unnamed Indian two-wheeler OEMs for vehicle integration testing scheduled to conclude in 2026, with commercial supply contracts expected to follow. India's Production Linked Incentive (PLI) scheme for advanced chemistry cell batteries provides government co-investment incentives for domestically manufactured cells — a framework Sodion is positioned to exploit as the only vertically integrated Indian sodium-ion cell producer currently operational. The company operates a pilot production line in Bengaluru targeting 100 MWh annual capacity as of 2026.
