CATL’s first-generation sodium-ion batteries now power 50,000+ Chery EVs in China, achieving market disruption:

• $57/kWh cell cost (15% below LFP)

• -40°C operation with 92% capacity retention

• 250,000-cycle lifespan (TU München validation)

Key innovations:
▶️ Hard carbon anode from biomass waste
▶️ Prussian white cathode (160 mAh/g capacity)
▶️ Aqueous electrolyte eliminates fire risk

Deployment Impact (2024):
✓ 10 GWh production at CATL’s Yibin plant
✓ 500 km EV range (HiNa Battery’s SIB packs)
✓ 100% charge in 15 minutes
