Dongwon Systems Begins Mass Production of Cylindrical Battery Cans for Secondary Batteries

[Asia Economy Reporter Song Seung-yoon] Dongwon Systems announced on the 19th that it has started mass production of 21700 standard (21mm diameter, 70mm height) cylindrical battery cans with more than 30% increased energy capacity compared to conventional standard cylindrical battery cans.

In January, Dongwon Systems became the first in the industry to develop technology to enhance the corrosion resistance of 21700 standard cylindrical battery cans, successfully producing finished products and obtaining product approval from domestic secondary battery manufacturers. Subsequently, it established a production system capable of mass-producing 21700 cans at its Chilgok plant located in Chilgok-gun and began sales last month.

To respond to the increasing demand for battery cans, Dongwon Systems plans to expand the scale of its secondary battery can manufacturing business by adding production lines within the first half of the year. A Dongwon Systems official stated, “We will expand factories and production facilities to secure domestic and international customers in line with the growing demand for cylindrical batteries,” adding, “We plan to secure differentiated technology for 4680 standard battery cans, considered next-generation cylindrical batteries, and introduce related production facilities to strengthen our portfolio as a secondary battery materials and components company.”

Following the expansion of its aluminum cathode foil production line for secondary batteries in 2020, Dongwon Systems acquired MKC, which has been supplying secondary battery cans to major domestic battery companies such as Samsung SDI and LG Energy Solution, in April last year.
