Tipical Processes
|
Designed for cylindrical, prismatic and pouch cell types
|
1.Designed for cylindrical, prismatic and pouch cell types
2.High tensile properties will avoid deformation forcells with higher stacks
3.High tensile strength at room temperature allows the use of thinner foil and a load of more active material during the coating process(improved manufacturing yield).
