-Larger-sized cylindrical batteries produced for micro mobility and to be expanded for EVs
-Product-portfolio diversified with 46-series, giving the company market leadership

[INQ. NO. 2504M12] SAMSUNG SDI recently announced that the company has embarked on production of its 46-series cylindrical batteries with a diameter of 46 mm, known as the next generation of cylindrical batteries.
SAMSUNG SDI has become the first Korean battery maker to start supplying 46-series batteries for overseas customers and plans to expand its customer base with this announcement.
The company said it recently marked the first shipment of 4695 battery modules from its Vietnam subsidiary.
The 4695 batteries, measuring 46 mm in diameter and 95 mm in height, are produced at SAMSUNG SDI’s plant in Cheonan, South Korea, and assembled into modules at the Vietnam subsidiary. The modules will be initially supplied for an American customer for use in micro- mobility applications.
SAMSUNG SDI proudly announced that the company has begun production of the next-generation products more than a year earlier than planned, owing to its differentiated manufacturing competitiveness, technological edge, and quality management.
SAMSUNG SDI’s 46-series batteries feature high-nickel NCA (Nickel, Cobalt & Aluminum) cathode and proprietary SCN (Silicon Carbon Nanocomposite) anode.

With its cutting-edge chemistry, the company has heightened both energy-density and lifespan of the cylindrical products, while preventing the batteries from swelling, as part of strengthening safety.
SAMSUNG SDI has also adopted a tabless design for the 46-series, where the electrodes are connected directly to the current collectors without the need for traditional tabs. This has improved the current flow path and reduced internal resistance by 90 percent, thereby providing higher outage.
In addition, the 46-series batteries are about six-times larger in energy capacity than the predecessor 21700 series of batteries, with a diameter of 21 millimeters and a height of 70 millimeters, enabling customers to use fewer cells for the same capacity.
SAMSUNG SDI unveiled its 46-series lineup, consisting of four sizes (4680, 4695, 46100, and 46120) at InterBattery 2025, the largest battery industry show held in Korea, on March 5-7. The company announced that it would commence mass-production within the first quarter of this year.
The company is currently in talks with major EV manufacturers for supplying its 46-series batteries. With the launch of 4695 production, the company expects to supply batteries for EV makers in the near future.
According to market-researcher SNE Research, the global market for the 46-series cylindrical batteries is forecast to grow from 155GWh this year to 650GWh in 2030, at an annual growth rate of 33 percent.
“With the initial supply of 46-series batteries, we have diversified our product portfolio. We will continue with our efforts to take the lead in the 46-series market with differentiated manufacturing technology and quality,” a spokesperson for the company remarked.
