Samsung Stacked Battery Technology
Samsung SDI, a subsidiary of Samsung Electronics specializing in battery technology, recently conducted public bidding for their new stacked battery mass production technology. In an unexpected turn, two Chinese manufacturers secured the bid, surpassing the competition from South Korean companies. While the names of the Chinese companies remain undisclosed, it has been revealed that they will establish offices in South Korea, working closely with Samsung SDI to further develop and promote this innovative battery technology.
Samsung SDI has already implemented stacked battery technology in the production of fifth-generation batteries for electric vehicles, where the stacking method enables enhanced energy density and compactness. Compared to existing methods, this stacking technique can increase energy density by over 10 percent. With this success, Samsung SDI aims to extend the application of stacked battery technology to smaller batteries intended for smartphones, tablets, notebooks, and other consumer electronics devices, hence the collaboration with the two Chinese manufacturers.
Samsung has faced criticism for lagging behind its competitors, such as Xiaomi, OPPO, Vivo, and Honor, in terms of charging solutions, particularly in wired fast charging. However, sources suggest that the upcoming Galaxy S24 Series from Samsung will incorporate stacked batteries, offering multiple benefits. This design not only minimizes battery bulging and associated safety risks but also enables a 10 percent increase in battery capacity while maintaining the same weight and volume.
Presently, Samsung employs the “winding” method for manufacturing smartphone batteries, which can lead to battery expansion and, in some cases, result in short-circuit combustion after a significant impact.
Samsung’s stacked battery technology is expected to make its debut in the Galaxy S24 Plus and Galaxy S24 Ultra, or possibly exclusively in the Galaxy S24 Ultra initially. On the other hand, Apple is also rumored to be considering the adoption of stacked battery technology across its entire iPhone 16 lineup.
According to insider information, the Galaxy S24 Plus and S24 Ultra will boast a 5000mAh rated battery capacity, representing an increase of nearly 150mAh compared to the previous generation. The Galaxy S24 Ultra will feature a unique stacked structure and incorporate cooling gel to ensure cooler operation during fast charging, enabling stable and rapid 65W wired charging. With this advancement, the charging time is expected to be reduced to approximately 40 minutes.
While Samsung is eager to incorporate stacked battery technology into their smartphones, it is important to note that the technology is still in the prototype phase, and no final decisions have been made. Enthusiasts are advised to stay tuned for further updates on this exciting development.
