Sodium-Ion Batteries Disrupt Energy Storage

Word Count: 199
Sodium-ion batteries have crossed a critical threshold in 2024, with CATL’s Dahua chemistry achieving 160 Wh/kg energy density – rivaling early lithium-ion. Key breakthroughs:

Hard carbon anodes using biomass waste (coconut shells)
Layered oxide cathodes with copper doping for stability
Ultra-fast charging: 15-min to 80% at -20°C

Deployed in China’s Three Gorges solar farm:
✅ 500MWh capacity at $57/kWh (35% cheaper than LFP)
✅ Zero thermal runaway in nail penetration tests
✅ 6,000-cycle lifespan with 93% retention
