BYD sodium-ion: 10,000-cycle battery and 50 GWh factory

Key Contributions

• 3rd-generation sodium-ion platform achieves 10,000 cycle life — a 3-5x improvement over LFP's typical 2,000-3,000 cycles
• 50 GWh sodium-ion factory in Xining represents largest dedicated Na-ion production facility announced
• First mass-produced sodium-ion forklift demonstrates industrial vehicle applications beyond grid storage
• 30 GWh production line already commissioned, indicating real manufacturing progress not just announcements

Results / Data

• Cycle life: 10,000 cycles (3rd-gen Na-ion)
• Factory capacity: 50 GWh (Xining)
• Commissioned capacity: 30 GWh line operational
• Application: first mass-produced Na-ion forklift
• Comparison: LFP typically 2,000-3,000 cycles
