LG plans to develop next-generation EV batteries


With the signing of the agreement, U.S. company 3M has granted LG Chem a license to a number of its U.S. patents as well as all global equivalents which include South Korea, Taiwan, Japan, China and Europe. The patents relate to the use of NCM in lithium-ion batteries.

This next-generation storage cell with NCM cathodes development is expected to increase efficiency and lower costs. The cathode materials can be tailored through composition and morphology changes to meet a wide range of customer requirements from portable devices to electric vehicles.

The main aim, with this acquired know-how, is the development of a new storage cell chemistry for affordable electric cars with a 320 km driving range by 2017. LG Chem is going to be working on developing large-capacity lithium-ion batteries that hold between 80 and 120 kWh with a single-charge-range target of 300-500 km.

LG Chem has been thus far producing lithium-ion batteries based on manganese spinel chemistry for automobile companies like Chevy, Ford, Hyundai and Renault. This year, LG Chem also bagged a deal with Daimler for battery supply for the new range of Smart electric vehicles. "LG Chem is a leader in the electric vehicle battery field, and NCM cathode compositions have shown significant benefit in large format applications, like electric vehicles," said Christian Milker, business manager, 3M Electronics Materials Solutions Division. "This license will accelerate the adoption of NCM technology to meet the growing demand for electric vehicles worldwide."
