BYD

Type: Company (EV Manufacturing + Battery — World's Largest EV Maker)

BYD is the world's largest EV manufacturer and second-largest battery maker, advancing on two parallel battery technology fronts: all-solid-state lithium for high performance and sodium-ion for cost-optimized applications.

Solid-State Battery

• Cell capacity: 60 Ah all-solid-state cell completed (production-representative, not lab sample)
• Vehicle timeline: 2027 target for vehicle installation
• Status: First production-representative cells manufactured and offlined

Sodium-Ion Battery

• Cycle life: 10,000 cycles — exceptional longevity (vs ~1,000-2,000 for typical Li-ion)
• Application: Grid storage, low-cost EVs, energy storage systems
• Cost advantage: Sodium is abundant and cheap vs. lithium supply constraints

Manufacturing Scale

• Chongqing Bishan facility: 20 GWh production line — substantial capacity commitment
• Cost target: $70/kWh — would make EVs cost-competitive with ICE vehicles without subsidies
• Vertical integration: From raw materials to finished vehicles

Key Contributions

• 60Ah all-solid-state cell offlined from production line (BYD Solid-State & Na-Ion)
• Sodium-ion achieving 10,000 cycle life (BYD Solid-State & Na-Ion)
• 20 GWh production line at Chongqing Bishan, $70/kWh target (BYD Solid-State & Na-Ion)
