Samsung To Manufacture EV Like Phone Batteries

According to reports, Samsung SDI‘s experience in electric vehicle (EV) batteries will soon help the mobile market. About a year ago, Samsung SDI started working on 5th generation batteries for electric vehicles using the stacking method instead of the traditional jelly roll technique.

This allows the components of the battery to be packed tightly together, which increases the capacity of the same volume. Now the company is preparing to use the same method for smartphone batteries.

Batteries manufactured using the stacking method produce at least 10% more capacity than conventional roll designs. To put things in perspective, a smartphone with a conventional flat jelly roll battery with a capacity of 5,000 mAh can take advantage of the same 5,500 mAh battery within the same size and shape. Alternatively, smartphones can be made thinner and lighter while keeping the battery capacity the same.

Flat-roll batteries, on the other hand, cannot be packed tightly because natural swelling can bend the electrodes when the battery is charged and discharged, thus damaging them in the process. However, the stacked design solves this problem by filling in the dead space inside the battery.

The company is reportedly planning to manufacture stacked-type smartphone batteries at its Cheonan plant in Seoul, South Korea. In addition, Samsung is expected to invest at least 100 billion won ($ 85 million) to equip its manufacturing lines for this work.

Meanwhile, another battery line is reportedly being developed at Samsung SDI’s Tianjin plant in China. So far, there is no word on when we will be able to see this stacked battery design inside the Galaxy smartphones, but hopefully, this technology will be ready for the Galaxy S23 series in time. The smartphone series should be introduced in the first quarter of 2023.
