Yes. Tafel 3.7V 120Ah Aluminum Case Large Unit Ternary Lithium Battery is a Grade A large unit battery. It is sold on JD.com and can be purchased, so large unit batteries of A grade can be purchased. A-grade large single batteries are batteries without abnormality in all parameters that meet the requirements of technical parameters. They are emergency power batteries for electric tricycles, electric motorcycles, motorhomes, etc.
What is the capacity of a large cell in CATL?
Flexible batteries are better.
Compared to large single batteries, flexible batteries have obvious advantages in terms of energy density, safety and manufacturing cost. Pocket batteries are made from lightweight, high-strength plastic materials and therefore have an energy densityhigher, allowing them to provide longer usage time and higher power output. In addition, the flexible soft battery design can effectively prevent internal short circuits caused by vibration or shock, thereby improving safety. On the other hand, large individual batteries may pose higher safety risks due to their larger size. In addition, the manufacturing cost of soft batteries is relatively low and is more suitable for mass production and applications. Therefore, considering the advantages of soft-pack batteries in terms of energy density, safety and manufacturing cost, it can be concluded that soft-pack batteries are better.
CATL 3.7V ternary lithium battery cells with high capacity lithium batteries for 40, 60 and 100 Ah electric vehicles. CATL uses Prussian white material with gra capacityms higher and innovatively reorganizes the charges in the overall phase structure of the material, which solves the problem of rapid decline in the capacity of Prussian white during cycling.
