On March 5, 2026, BYD introduced its second-generation Blade Battery and accompanying flash-charging technology. The new architecture divides the lineup into two formats—Short Blade and Long Blade—to address different performance and range requirements.
The Short Blade 2.0, with cells measuring approximately 450–580 mm, is optimized for rapid charging. It supports an 8C peak charge rate and a 16C peak discharge rate, enabling a 10% to 70% state of charge in about five minutes. The design incorporates a “Lithium-Ion High-Speed Channel” with a multi-level particle-size cathode structure, which enhances ionic conductivity and manages the thermal loads associated with up to 1,500 kW of charging power. This format is intended for high-voltage (800V–1,000V) platforms and plug-in hybrid powertrains.
The Long Blade 2.0 focuses on energy density, achieving a system-level figure of 190–210 Wh/kg—roughly 40% higher than the first generation. It uses lithium manganese iron phosphate chemistry at a nominal voltage of 3.8V. In practical terms, a 120 kWh Long Blade pack in the Denza Z9 GT delivers a CLTC range of 1,036 kilometers.
| Attribute | Specification |
|---|---|
| Battery Name | BYD Blade Battery 2.0 |
| Launch Date | March 5, 2026 |
| Chemistry | LMFP (Lithium Manganese Iron Phosphate) |
| Architecture | Blade cell format with two variants: Short Blade and Long Blade |
| Integration Technology | Cell-to-Body (CTB 2.0) |
| Space Utilization | Up to 76% volumetric efficiency |
| Charging Infrastructure | Supports up to 1,500 kW flash charging |
| Attribute | Short Blade 2.0 | Long Blade 2.0 |
|---|---|---|
| Cell Length | 450–580 mm | ~960 mm |
| Chemistry | LMFP (High Power) | LMFP (High Energy) |
| Energy Density | 160 Wh/kg | Up to 210 Wh/kg |
| Max Charge Rate | 8C | 3C |
| Max Discharge Rate | 16C | 8C |
| Primary Focus | Ultra-fast charging | Maximum driving range |
| Typical Vehicle Type | Performance EVs / PHEVs | Long-range BEVs |
| Example Vehicles | Performance platforms with flash charging | Denza Z9 GT, Yangwang U7 |
Both formats are integrated into an updated cell-to-body structure (CTB 2.0), which raises volumetric utilization to about 76% while lowering overall structural weight.
In comparison with competitive offerings such as CATL’s Kirin battery, the Blade 2.0 series provides similar range performance at a reduced production cost. To support the 8C charging capability of the Short Blade, BYD has announced plans to deploy 20,000 flash-charging stations—each equipped with 1,500 kW T-shaped dispensers—by the end of 2026.
The Blade 2.0 pack is currently standard on the Yangwang U7, which carries a starting price of ¥1.09 million (approximately $150,800), and is slated to become available on the Ocean series by the third quarter of 2026.
