ESS Solution

LG Chem’s Strength of Energy Storage System(ESS)

High Energy Density

Higher density can be realized through LG Chem's ‘Lamination & Stacking’ process, which minimizes dead space and enables higher energy capacity than the typical ‘Winding’ process. Therefore, LG Chem’s Lamination & Stacking process provides a high degree of freedom to manufacture thick & highly-dense electrodes.

Longer Lifespan

LG Chem’s Lamination & Stacking structure allows the cell to maintain its structure for a longer period of time than a typical winding structure.
This sustainability of cell structures allows for longer lifespans.

Cell structure with extended lifespan

LG Chem’s pouch type cell also contributes to longer lifespans because the wide footprint allows for more effective heat dissipation than is possible with the prismatic type cell with its longer heat dissipation path.

Safety & Reliability

LG Chem is constantly seeking improvement of its battery systems.
Information and experience gathered onsite is reflected in the R&D phase as well as mass-production.
This quality improvement cycle enables LG Chem to prevent failures or other issues in advance and enhance the quality of its products.
There have been no reported field issues with LG Chem's automotive and battery storage products since production commenced in 2010.

Quality improvement cycle

Every lithium ion battery cell has a separator between the positive and negative electrodes which prevents internal short circuits occurring.
LG Chem’s SRS(Safety Reinforced Separator) has a ceramic coated layer and increased mechanical/thermal stability to prevent contamination of
the separator and enhance its integrity and durability.
