Is the BYD Blade battery lithium iron phosphate?

Introduction Is BYD's blade battery lithium iron phosphate? BYD's blade battery is lithium iron phosphate. There are two main materials for lithium batteries used in new energy vehicles.

Is the BYD Blade battery lithium iron phosphate?

The Pacific Automotive Network BYD blade battery is lithium iron phosphate. There are two main materials for lithium batteries used in new energy vehicles. One is called ternary lithium battery and the other is called lithium iron acid battery. . The advantage of ternary lithium battery is that the energy density of the battery is higher than that of lithium iron phosphate under the same weight, and the discharge power of the battery is also higher than that of lithium iron phosphate battery . The disadvantage is that once the ternary lithium battery appears, an internal short circuit will cause a violent reaction, accompanied by an open flame, and the safety performance is lower.

What is the difference between blade batteries, ternary lithium batteries and lithium iron phosphate batteries?

The blade battery is essentially a lithium batteryum iron phosphate, but its structure is different from ordinary lithium iron phosphate batteries. It removes the battery module and uses new packaging technology, which has higher energy than traditional lithium iron. Phosphate batteries. The density is higher, close to the energy density of ternary lithium batteries, which also improves battery life.

Acupuncture test shows that blade batteries are more stable and safer. The “needle penetration test” is recognized in the industry as the most stringent testing method for battery cell safety. The acupuncture test uses steel needles. . Puncture the power battery cell, causing a large short inside the cell. Please see below the specific performance of different batteries in acupuncture experiments.

The ternary lith batteryium experiences drastic temperature changes at the time of acupuncture. The surface temperature quickly rises to 500 degrees and extreme thermal runaway occurs. Eggs on the surface of the battery are blown away by the wind; After the lithium battery was pierced, there was no longer any open flame or smoke, and the surface temperature reached 200°C~400°C, and the eggs on the surface of the battery were burned by the high temperature after BYD blade battery; " was penetrated, there was no open flame or smoke, and the surface of the battery. The temperature is only about 30-60°C, and the eggs on the surface of the battery did not changed and are still in a flowing liquid state. The comparison results of acupuncture experiments fully demonstrate that BYD's blade batteries can effectively prevent the occurrence of "thermal runaway", thus demonstrating excellent safety. /p>

Blade batteries have beenused in BYD Han models. BYD Han EV is the first model to use Blade batteries. Not only has safety been significantly improved, but the cruising range has also been increased, reaching 600 kilometers. , the latest BYD Yuan Pro is said to also use blade batteries. It is believed that in the near future, all BYD new energy vehicles will gradually use blade batteries with greater safety.
