Samsung SDI Co., Ltd.

Company Background

Samsung SDI is a South Korean electronic component maker that belongs to the Samsung Electronics group.

The world's largest supplier of lithium-ion batteries, it is locked in heavy competition with domestic and Japanese rivals in lithium-ion batteries for cell phones, cars and solar power plants.

The company was jointly established by the Samsung group and Japanese electronics maker NEC in 1970. It began as a manufacturer of picture tubes. The company has used its current name since 1999.

Samsung SDI manufactured organic light-emitting diode display panels and plasma panels by itself even after dissolving the joint venture with NEC. But it has since farmed out all display panel operations to other group companies.

The company now manufactures batteries, which account for roughly 50% of its sales, polarizing plates for liquid crystal display panels and materials for semiconductors and display panel.

It supplies most of its products to Samsung group companies.

Samsung SDI is the largest shareholder in trading house and construction company Samsung C&T. The leading shareholder in Samsung SDI is Samsung Electronics.

Market participants predict Samsung SDI will be included in the reorganization of group companies that the Samsung group is carrying out to streamline its complicated capital ties.
