The era of ‘BoT (Battery of Things)’*—where batteries become the core of everything around us—is drawing near. From robots and IT devices to electric vehicles, batteries already serve as the driving force behind countless machines.

* BoT refers to a world in which batteries power all kinds of devices and become the core of the future energy industry.

Various devices that use batteries each require different battery performance. In the case of power tools and garden tools, where SAMSUNG SDI holds the No. 1 market share, high output is the top priority. Power tools are used to cut or process hard materials such as concrete and metal, while garden tools often handle thick wood. They both require batteries capable of delivering large amounts of energy rapidly.

Fast charging is also important, as completing a charge during a short break between tasks can greatly enhance both work efficiency and user convenience.

Garden tools such as lawn mowers and leaf blowers also require high capacity feature as they are often used for continuous operation over large areas and must run for long time on a single charge.

Unlike power tools, which are typically operated with one hand and therefore have strict weight limitations, garden tools have less strict weight limitations, allowing for the installation of larger batteries to maximize capacity.

To meet these requirements, the industry has predominantly chosen cylindrical batteries. Encased in a metal can, they deliver high output and stable performance even in environments with frequent changes, such as construction sites or outdoor workplaces.

SAMSUNG SDI applies low resistance technologies such as a tabless structure and graphite particle realignment to achieve high output and fast charging features that go beyond the inherent advantages of the cylindrical design.

The graphite particle realignment technology aligns graphite particles in a uniform direction and facilitates fast charging. By orienting the lithium-ion pathways in a single direction, it enables faster lithium-ion transport during charging.

SAMSUNG SDI produces cylindrical batteries in 18650* and 21700* sizes for power tools and garden tools.

In addition, it offers a wide range of products with varying output levels, allowing customers to choose the most suitable option for their specific needs. 

Base on its advanced cylindrical battery technology, SAMSUNG SDI has maintained the No.1 market share in the power tool and garden tool sectors for several years. The company plans to continue strengthening its competitiveness in these markets through continuous technological innovation.
