The “Blade battery” is a lithium iron phosphate battery. Which BYD target market?

As we all know, current pure electric vehicles are mainly equipped with ternary lithium batteries, and some models use lithium iron phosphate batteries. Comparing these two batteries, the ternary lithium battery has higher energy density, which can improve the cruising range of pure electric vehicles and account for a higher market share. However, among domestic battery manufacturers, BYD's main business is lithium iron phosphate batteries. In addition, at the China Electric Vehicles Conference of 100 Forum, the chairman of BYD said that the new generation of lithium iron phosphate batteries developed by BYD - "Blade Battery" will be mass-produced this year. The “Blade battery” is a lithium iron phosphate battery. Which BYD target market?

As mentioned above, “blade batteries” are also acid batteries.ithium iron phosphate. As a lithium iron phosphate battery, it has a longer service life and higher stability than ternary lithium batteries. From the point of view of thermal stability, ternary lithium battery materials will decompose at about 200 degrees, while lithium iron phosphate materials will decompose at about 800 degrees, so to a certain extent, the thermal stability of pure electric vehicles can be reduced. . In addition, according to BYD's official information, the volume-specific energy density of the "blade battery" is 50% higher than that of traditional iron batteries, and the production cost is reduced by about 30%, which improves also its competitiveness.

From this point of view, the "blade battery" developed by BYD can, on the one hand, improve the endurance performance and stability of its models, and on the other hand, it can compete for powercurrent. battery market. Because "blade batteries" increase energy density to a certain extent, reduce production costs and improve stability, they can compete with ternary lithium batteries to a certain extent.

However, although the energy density of "leaf batteries" has been improved compared with ordinary lithium iron phosphate batteries, this is basically only a structural change and does not imply of material changes, which is why it is called "pseudo-innovation" by many Internet users. However, the "blade battery" has improved the cruising range by ensuring stability at the current stage, and its market competitiveness is also considerable. I wonder what everyone is thinking?

Advantages and disadvantagesients of blade batteries

Pacific Automotive Network BYD's blade batteries are lithium iron phosphate, the main materials of lithium batteries used in new energy vehicles. are: There are two types, one is called ternary lithium battery and the other is called lithium iron phosphate 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 baterie blade is basically a lithium iron phosphate battery, but its structure is different from ordinary lithium iron phosphate batteries. The battery module is removed and a new gasket is used.The energy density of the battery is higher than that of the traditional lithium iron phosphate battery, which is close to the energy density of the ternary lithium battery, so the Battery life is also improved.

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 experiments.es of acupuncture.

The ternary lithium battery 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 e.excellent security.

Blade batteries were used 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.

The advantages of blade batteries are: high density high energy, high sexual security. . Disadvantages include: limitations and maintenance difficulties.

1. Advantages

1. High energy density: Blade batteries use high energy density cathode materials, which can increaseSignificantly reduce the capacity and endurance of the battery. This is a major new technological upgrade in the field of energy vehicles.

2. High Safety: The blade battery uses solid electrolyte, which will not cause safety problems such as short circuit or thermal runaway that are common in traditional lithium-ion batteries, greatly improving the safety of the battery.

2. Disadvantages

1. Limitations: Blade batteries have a relatively narrow use range and are mainly used in the field of new energy vehicles. It is not applicable to other areas, such as smartphones, laptops, etc.

2. Difficulty in Maintenance: Since the blade battery uses solid electrolyte, if damaged or damaged, it will be difficult to repair and require professionals to handle it.

Struct analysisurality of blade batteries

Many people think that blade batteries are a completely new battery technology, but they are essentially lithium iron phosphate batteries. The traditional cylindrical-shaped single battery was transformed into a long and thin blade-shaped single battery, so it was called a blade battery.

Compared with traditional single-cylinder batteries, stacking creates too many spaces between batteries. Flat blade batteries can make full use of the space inside the battery assembly, and the advantages are obvious, and more individual cells can be placed. .Blade battery, thereby increasing the energy density of the battery per unit volume.

The Blade battery is a structural innovation of the lithium iron phosphate battery. It adopts Ningde CTP module-free solution. Due to changes in cell structureire, the battery design has also changed, eliminating the hull structure. traditional battery. , the blade battery acts as the battery harness and also acts as a cell.
