IT & New Application Battery
Cutting-edge technologies with industry-leading competitiveness

In the rechargeable battery, lithium-ions move between cathode and anode to produce electricity. The battery is used for a variety of devices such as smartphones and laptops. In 1999, LG Chem succeeded in developing a lithium-ion battery for the first time in Korea. Since then, It has continued to increase its sales volume in the battery market based on its competitive technologies and innovative product development.

[Ultra-slim Shape] LG Chem's patented 'Stack & Folding' structure

LG Chem's patented 'Stack & Folding' structure by which one or more bi-cells are stacked and folded on the separator can implement ultra-slim batteries with a thickness. This is a differentiated solution that cannot be implemented by the conventional winding polymerstructure and can only be offered by LG Chem's polymer batteries.
