Recently, CATL launches a new long life battery. The battery adopts self-repairing long life technology, achieving 16-year long life or 2 million mileage, cost compared to current battery no more than 10%. CATL self-repairing long life battery technology is slowing down capacity attenuation speed, that is, controls the activated lithium consumption speed.
Capacity attenuation is related to positive electrode, negative electrode, and electrolyte. At the positive pole, the storage process activity is lowered by self-sleep passivation film technology, and then activated when used, thereby greatly reduces the side reaction during cycle and storage. In the negative electrode, the surface stability and body phase stability of the negative electrode material are significantly enhanced by low lithium consumption, and the active lithium consumption during the battery cell is greatly reduced, and the performance requirements of long life are achieved.
At the same time, bionic electrolyte technology exhibits self-adaptive protection characteristics according to the demand of film in different life cycles of the cell, and enhances the circulation and storage performance of the battery. In the end, this technology "combination box" effectively suppresses the side effects to extend battery life. The technology is generally used in three-membered materials and lithium iron phosphate materials, which already has the amount of production force, which can alleviate the pain points of the user mileage attenuation, greatly reduce the cost of battery use, and improve the electric vehicle related to the economics of the fuel vehicle.
