The LFP battery is designed to offer maximum safety, stable range, and an exceptional lifespan exceeding 5,000 charge cycles. It is considered one of the safest batteries in the world and is the heart of BYD's electric and hybrid vehicles.
The safe heart of BYD electric and hybrid vehicles
The Blade Battery is a lithium iron phosphate (LFP) battery developed by BYD through 29 years of innovation. It is stable, safe, and designed to deliver consistent performance in both fully electric models and plug-in hybrids with DM-i technology.
Recognized as one of the world's safest batteries for electric and hybrid vehicles.
Blade Battery (LFP) vs. Traditional Batteries (NCM): The Comparison
Blade Battery's LFP technology offers significant advantages over traditional NCM (Nickel-Cobalt-Manganese) batteries:
| Characteristic | BYD Blade Battery (LFP) | Traditional Batteries (NCM) |
|---|---|---|
| Safety | ✓Passes nail penetration test without smoke or flames | ✗Fire risk in extreme conditions |
| Cycle duration | ✓Over 5,000 charging cycles | ~1,000-2,000 cycles |
| Thermal stability | ✓Surface temperature 30-60°C in extreme cases | ✗Possible thermal runaway above 200°C |
| Oxygen emissions | ✓No emissions (lower fire risk) | ✗Release of oxygen in case of overheating |
| Environmental impact | ✓More sustainable materials (iron and phosphate) | Cobalt and nickel (limited resources) |
| Space efficiency | ✓plus 50% compared to traditional parcels | Standard |
| Degradation | ✓Very slow over time | Faster after 3-5 years |
Conclusion: BYD’s Blade Battery represents a quantum leap in electric vehicle battery technology, offering superior safety, greater longevity, and better performance over time than traditional solutions.

This test is one of the most stringent in the battery industry. It simulates what could happen in a serious accident, when metal objects could penetrate the battery's structure.
The Blade Battery passed the test with exceptional results and maximum reliability:
Blade Battery's LFP technology offers high safety: the stable chemistry does not release oxygen, produces little heat and the long shape of the cells ensures uniform cooling.
Even in the event of impacts or overheating, heat is dissipated and the battery does not reach critical temperatures, reducing the risk of fire.
BYD's Blade Battery uses long, flat blade-shaped cells nested in a honeycomb structure without intermediate modules, resulting in a compact, high-density battery pack.
In Cell-to-Body versions, the battery becomes part of the frame, optimising internal space and lowering the centre of gravity, for greater stability and safety of the vehicle.
The internal blade design increases strength and weight distribution, reducing deformation in the event of an impact.
It is a battery designed by BYD engineers to offer greater protection, safety and reliability over time, integrating into the vehicle structure and helping to provide greater stability, efficiency and daily driving comfort.
The LFP chemistry guarantees over 5,000 charge cycles while maintaining high performance. Thanks to superior thermal stability and reduced degradation over time, the Blade Battery retains its capacity much longer than traditional NMC batteries.

Complete battery coverage to give you maximum peace of mind over time.
Every Blade Battery goes through rigorous testing before being installed in our vehicles.
Maintains at least 70% of original capacity throughout the warranty period.
Blade Batteries already equip millions of BYD vehicles worldwide with excellent performance.
The Blade Battery is an LFP battery designed by BYD to offer greater safety, a long lifespan, and stable performance over time. It’s the same technology used in BYD’s electric and hybrid models.
The standard warranty is 8 years or 250,000 km, with a guaranteed residual capacity of more than 70% (SOH > 70%) for the full warranty period. This is one of the most comprehensive warranties in the sector.
Because it has passed extreme tests such as the nail penetration test, maintaining a stable temperature without releasing smoke or flames. It is one of the safest batteries in the world.
It can exceed 5,000 charge and discharge cycles, ensuring many years of use with consistent performance. It retains capacity longer than many traditional battery technologies.
The Blade Battery is available across BYD’s entire range of electric vehicles (BEVs) and plug-in hybrid (DM-i) models.
Charging can be done via AC (alternating current) stations or DC (direct current) fast chargers. BYD vehicles support DC fast charging to shorten charging time.
Replacement costs depend on the specific car model and contract conditions, but the Blade Battery’s long life means replacement is typically required only after many years or hundreds of thousands of kilometres.
Yes. Blade Batteries are designed to be recyclable, with processes that help recover valuable materials and reduce electronic waste.
