Sodium-ion batteries are emerging as a cost-effective and sustainable alternative to lithium-ion technology for EV applications. By 2025, the global sodium-ion battery market is projected at $1.2 billion, expanding to $5.6 billion by 2030, representing a CAGR of 33%. This growth is driven by lower material costs, abundant sodium resources, and improvements in energy density from 120 Wh/kg in 2025 to 180 Wh/kg by 2030. Early adopters, including Chinese battery manufacturers and European OEMs, are piloting sodium-ion batteries for urban EVs and two-wheelers, targeting cost-sensitive fleets.
‍

Cost analysis shows that sodium-ion battery packs are 15–25% cheaper than lithium-ion equivalents at the pack level, reducing total EV costs by $3,500–$5,000 per mid-size vehicle. Supply chain advantages, including local sodium sourcing and simpler cathode processing, reduce production lead times by 20–25%. Competitive dynamics indicate that companies with proprietary electrolyte formulations or high-cycle stability patents can secure 30–35% market share in early commercialization.
