Samsung SDI technology could be used to make LG and Hyundai electric vehicle batteries

Samsung SDI is doing a lot of innovations in the field of battery technology and trying to increase the energy density with the new pouch stacking tech. SDI is successful in developing this technology and could feature this in its upcoming foldable.

According to the report of ‘TheElec,’ Hyundai Motor Company and LG Energy Solutions are going to use the Z-stacking method for their electric vehicles battery production, which is purely based on Samsung SDI technology.

The process uses stacking battery material such as a positive electrode, a negative electrode, and a separator. The separator creates a pouch-like structure, which helps in holding the power for a longer duration. This battery assembling method provides high stability.


The battery looks singular as an individual but is plural from the inside. The storage cells are sandwiched between the positive electrode and the negative electrode, repeatedly no. of times to create a bunch of stacking pouch.

The basic difference between the technology of LG and Hyundai is the lamination. This focuses on enhancing the battery stability than its performance. Because the load itself is responsible for the extended or drowned capability.

Advance lamination technology can provide up to 99% high yield and productivity rate but the art is only in the stacking process to successfully attach these electrodes without any kind of error.

The production of the batteries could be started sometime in 2024 by the joint venture of LG and Hyundai. Let us see whether they could provide any competition to the Samsung SDI technology in the coming day.
