CATL's new long-life battery is practical -Lithium - Ion Battery Equipment

CATL has become the "overlord" of the global power lithium battery in ten years, and has gradually formed a positive cycle business model with leading technology, low battery cost, and large production and sales scale.

Based on this, CATL is a company that is willing to engage in technology. This is one of the reasons why CATL has created an industry myth in just ten years; it is also one of the reasons why CATL can buck the trend and expand its market share despite the first negative increase in sales in my country's new energy vehicle industry in the past ten years.

On June 10, CATL announced the launch of a new long-life battery, which can run continuously for 16 years, support electric vehicles to travel 1.24 million miles, and cost less than 10% more than the existing power lithium battery.

1.24 million miles, a power lithium battery with a lifespan of up to 16 years, what concept? Let's put it this way, the current domestic standard for electric vehicle batteries is 8 years and 240,000 kilometers, and CATL's power lithium battery with a lifespan of up to 16 years can support electric vehicles for 2 million kilometers. You taste, you taste carefully.

BYD expressed dissatisfaction and showed the 50-meter "blade" in its hand. For car companies, the safety of power lithium batteries is the fundamental issue. The relationship between energy density and safety of ternary lithium batteries must be squarely faced. Security issues have not been resolved, so there is a 'hammer' to use? Do you dare to try it again?

CATL smiled slightly. "Needle sticking" can't prove safety. In the past, the big guy Sony played "needle sticking", not because of safety accidents. Blade battery is just one of CTP. CATL made CTP four years ago, and selected several optimal methods from it, which has been applied to passenger cars on a large scale.

This time, the core of the new long-life battery announced by CATL is to slow down the speed of capacity decay. For the positive electrode, the new technology reduces the activity of the storage process through the self-dormancy passivation film technology, and reactivates it when used, thereby greatly reducing the side reactions of the positive electrode material during cycling and storage. In terms of negative electrodes, the new technology significantly enhances the surface stability and bulk phase stability of negative electrode materials through low lithium consumption technology, greatly reduces the consumption of active lithium during the use of cells, and achieves performance requirements for ultra-long life.(Lithium - Ion Battery Equipment)

At the same time, the bionic electrolyte technology can display adaptive protection characteristics according to the needs of film formation in different life cycles of the cells, and improve the cycle and storage performance of the cells. In addition, this technology is commonly used in ternary materials and lithium iron phosphate, and it already has the capacity for mass production, which can alleviate the pain point of user mileage attenuation, greatly reduce the cost of battery use, and improve the economy of electric vehicles related to fuel vehicles.

From the perspective of market development, the current automotive power lithium batteries are developing towards a long life. CATL's new batteries are really powerful in this regard. Iron phosphate batteries currently cannot achieve such a long life. Therefore, before the breakthrough of the new technology of power lithium battery, CATL's new battery is actually more practical than BYD's blade battery.

In addition, when it comes to the safety of power lithium batteries for electric vehicles, lithium iron phosphate batteries are theoretically safer than ternary materials, but it still depends on the actual application situation. Among CATL suppliers, there are visible reports of battery fires. Take Weilai as an example, and it seems that the important responsibility is still in Weilai's pack.

In addition, the cooperation between car companies and battery companies requires a relatively high investment cost for both parties and requires long-term running-in, so they will not only focus on one route of development. Taking CATL and TSLA as examples, according to CATL, TSLA can supply whatever battery they want, and it will not be limited to ternary materials or lithium iron phosphate.

In the field of electrochemistry, it generally takes ten years or more for a new material and new technology to move from the laboratory to the social application level. Therefore, the product and technological progress of lithium batteries can only be completed by the coordination and cooperation of the whole industry chain. CATL has always followed the "four complete" road (full scene, full cycle, all-round, and full system) to ensure safety from the perspective of real use.
