High Capacity Lithium Ion Polymer BatteryE1 and Standard Pack (7s)Introduction of Battery Business in LG Chem, LTD.

LG Chem has been successful in developing Li-Ion batteries for the first time in Korea since 1999. By establishing a stable mass production system, we are able to supply our batteries to major local and international communications companies and now enjoy a worldwide recognition for our batteries.

LG Chem is investing 1,000 billion KRW to construct the new specialty production site for information and electronic materials - Techno Park in Ochang, North ChungcheongProvince. With our leading-edge technology, high value created products and concentrated investments, we are also striving to be the world’s top three manufacturer by 2005.

High Capacity Lithium Ion Polymer BatteryE1The E1 cell is a newly-developed lithium ion polymer battery, whose capacity is as high as 10 Ah, by LG Chem, Ltd.

This cell is specially designed for any application where high power and long autonomy are required, such as light electric vehicles including E-bikes.

To satisfy requirements of safety and performance, manganese-based oxides are employed as cathode materials instead of lithium cobalt oxides. In addition, to secure safety, an unique BMS (battery management system) has been developed for battery packs.

For your system requirements, please contact LG Chem.

High Capacity Lithium Ion Polymer BatteryStandard Soft PackThe standard soft pack has been developed with batteries in series and BMS (battery management system) by LG Chem, Ltd. Since this standard soft pack has a flexible design, it is easily modified to various outfits and the number of serial connection.

The BMS has three main functions. First is directly related to Safety. It can protect the batteries and equipments from over-charge, over-discharge, external short circuit, over-temperature by monitoring the voltage, current, and temperature of the batteries. Next function is enhancing performance by cell balancing during charge. And the last is for improving convenience such as fuel gauging, communication, and history recording functions. All functions can be modified by customers’requirements.

For your system requirements, please contact LG Chem.
