Word Count: 199
CATL’s Dahua sodium-ion batteries are reshaping electric mobility in 2024:
$56/kWh cell cost (48% cheaper than LFP)
200,000-cycle lifespan validated in BYD buses
-40°C operation with <20% capacity loss
Deployed in 500,000 EVs globally this year:
✅ Zero cobalt/nickel – eliminates mining ethics concerns
✅ 4C fast-charging: 15-minute 80% charge
✅ 160 Wh/kg energy density (matching early NMC)
"This democratizes EVs for emerging markets" – Dr. Elena Schmidt, BloombergNEF.
