Is BYD blade battery a ternary lithium battery

BYD blade battery is not a ternary lithium battery, but an innovative lithium iron phosphate battery.

In the lithium-ion battery family, lithium iron phosphate batteries and ternary lithium batteries have different usage scenarios due to differences in chemical composition. BYD blade batteries use lithium iron phosphate as the positive electrode material, and optimize the spatial layout through unique design to enhance energy density. This type of battery not only has the high safety and long cycle life of lithium iron phosphate batteries, but also achieves comparable range performance to ternary lithium batteries to a certain extent.

From a safety perspective, blade batteries, as a major highlight of lithium iron phosphate batteries, have excellent thermal stability and are not easily lost control in high temperature environments. In the needle puncture test, the blade battery will not have open flames or smoke, fundamentally reducing the risk of spontaneous combustion. In addition, the blade shaped battery cells make the short-circuit circuit longer and the heat dissipation surface area larger, further ensuring the safety of the battery.

In terms of energy density, blade batteries have achieved breakthroughs through technological innovation. The traditional battery has a low space utilization rate, while blade batteries increase the space utilization rate to around 60%, making their energy density comparable to mainstream ternary lithium batteries, thereby achieving a higher range and allowing vehicles to travel longer distances after a single charge.

In terms of cycle life, blade batteries perform exceptionally well. It still maintains a high capacity retention rate even after being charged and discharged more than 3000 times. This means that during long-term use, the battery performance deteriorates slowly and can continue to provide stable and reliable power support to users.

In terms of cost, blade batteries also have significant advantages. Due to the abundance of raw materials and relatively low prices, after large-scale production, costs are further reduced, enhancing the market competitiveness of the product.

In addition, blade batteries perform well in low-temperature performance, with a discharge capacity of up to 90% of room temperature at minus 20 degrees Celsius. They also have strong adaptability and can be applied to different types of electric vehicles.

In summary, BYD blade batteries, as a new type of lithium iron phosphate battery, have shone in the field of new energy vehicles with many unique advantages. It not only continues the advantages of safety and long life of lithium iron phosphate batteries, but also makes breakthroughs in energy density and range, providing new strong support for the development of new energy vehicles and driving the industry to new heights.
