BYD's second-generation Blade Battery and flash-charging technology are gradually rolling out across the entire vehicle lineup, and the delivery cycle extensions caused by capacity bottlenecks have significantly eased. The Denza N8L flash-charging version, launched in mid-June, features the latest 5C flash-charging technology, with official guide prices of 319,800 and 349,800 yuan. As production line upgrades are gradually completed, delivery cycles for multiple BYD best-selling models have returned to normal levels. The second-generation Blade Battery offers improvements in energy density, safety performance, and charging efficiency, and combined with flash-charging technology, BYD's product competitiveness is gaining new technical support.
2nd Gen Blade Battery: Energy Density and Safety Dual Upgrade
BYD officially launched its 2nd generation Blade Battery in July 2026 with comprehensive upgrades:
| Parameter | 1st Gen Blade Battery | 2nd Gen Blade Battery | Improvement |
|---|---|---|---|
| Energy density | 140-150 Wh/kg | 190-200 Wh/kg | +35% |
| Volume utilization | 60% | 75% | +15pp |
| Fast charging rate | 2C | 5C | 2.5x |
| Cycle life | 3,000 cycles | 5,000 cycles | +67% |
| Nail penetration test | No fire | No fire + no smoke | Enhanced |
| Low-temp performance | -20°C 40% degradation | -20°C 20% degradation | Major improvement |
The 2nd generation uses LFP chemistry but achieves near-NCM energy density through structural innovation, while maintaining LFP's inherent safety advantages.
Technical Breakthroughs
- Stacking process upgrade: New internal stacking structure increases space utilization from 60% to 75%
