Samsung SDI's experience in making batteries for electric cars could soon be used in the field of smartphones. The Samsung division reportedly plans to use layered battery technology from electric cars to produce smartphone batteries with increased capacities.
Batteries in smartphones use the so-called flat jerry roll design. Switching to a layered design similar to the one used by batteries in electric cars could yield roughly a 10% increase in smartphone battery capacity without increasing its size.

According to Korean website The Elec, citing SamMobile, Samsung plans to produce batteries with a layered design at its factory in the city of Cheonan. For this purpose, he intends to invest at least 100 billion won (roughly CZK 1,8 billion) in the equipment of the production line.

Another pilot production line is to be prepared at the Samsung SDI factory in the Chinese city of Tianjin. At the moment it is not clear when we will have a new battery design in smartphones Galaxy they could wait, however, it is possible that it will be ready in time for the series Galaxy S23. It should be launched in the first quarter of next year.
Cylindrical cells actually have a higher density of stored energy, but they use up space in the shape of a square thanks to the round shape, so I somehow miss the benefit of using a surface prismatic cell. Unless Samsung is planning a mobile in the shape of a stick with a scrolling display 🙂
