Samsung is reportedly planning to utilise the ''jelly-roll'' technique for its Galaxy S23 flagship batteries as well. Additionally, a tipster has suggested that the application of this technique might increase the battery capacity of the Galaxy S23 series in comparison to the Galaxy S22 lineup.
The Samsung Galaxy S23 series, which has been coined Project Diamond, will benefit from the stacking technique. Similarly, Samsung is planning to incorporate the Galaxy S23+ with a 5,000mAh battery and the Galaxy S23 Ultra with a 5,500mAh capacity. According to experts, the Galaxy Z Fold 4 is unlikely to be used with this technology.
According to a statement from The Elec, Samsung SDI has established a pilot production line in Tianjin, China, for testing the stacking method. Moreover, the company is reportedly developing four of the 12 production lines at the M Line in Cheonan, South Korea, for mass-produced smartphone batteries, using this technology.

In contrast to the jelly roll technique, the stacking technique is alleged to increase battery energy density by 10 percent, respectively. Moreover, it may allow smartphone manufacturers to produce thinner and lighter handsets with the same or improved battery capacities. Another advantage the stacking technique has over the ''jelly roll'' technique, is that rolled batteries cannot be tightly packed because of their natural tendency to swell. The stacking process supposedly eliminates this limitation, allowing manufacturers to waste less space inside the battery.
