LG Chem



Automotive Battery

World's No. 1 automotive battery supplier

The rechargeable battery for automobile is a mid- to large-sized lithium ion battery used to provide power to an electric vehicle. Lithium ions move between the (+)/(-) electrodes to produce electricity. Based on its cutting-edge technologies, LG Chem has lead the global market by supplying batteries for electric vehicles to the global automobile manufacturers.


Batteries for electric vehicles demand high stability, high output and high energy density, and, in this regard, LG Chem's products are fully recognized for their performance and quality.
Models equipped with LG Chem's battery

For Hybrid Vehicle(HEV)

Hyundai Sonata
  • A significant improvement in fuel efficiency through output increase.
  • Excellent instantaneous output/charging performance.
  • Long lifespan despite the frequent charging/discharging thanks to the little distortion/degeneration of electrodes.

For Plug-in Hybrid Vehicle(PHEV)

GM Volt
  • Realized high energy density for the same volume.
  • Outstanding driving performance in the EV mode due to the high output.

For Electric Vehicle(EV)

Renault ZOE
  • Secured high capacity per unit weight thanks to the light battery, increasing the travel distance.
  • Uniform temperature ensures sufficient cooling with a small amount of energy, extending the lifespan of the battery.
* In addition to the examples listed above, LG Chem can provide automobile batteries in the form of cell, module or pack depending on the vehicle.
