LG Chem to Enforce Patent for High-Nickel Cathode Battery Materials

LG Chem to Enforce High-Nickel Cathode Patent

LG Chem aims to enforce its battery material patent rights amid intensifying EV competition.

LG Chem has proposed to license out its high-nickel cathode material patent to China-based cathode material suppliers. To that end, LG Chem plans to enforce its patent rights against other global cathode material companies. 

The licensing offers were made to companies that mainly operate in the manufacture of high-nickel cathode materials. High-nickel cathodes are essential materials for high-performance EVs as they play a crucial role in increasing the energy density of batteries to extend the driving range.

In March 2022, LG Chem, one of the world’s first producers of nickel-cobalt-manganese (NCM) cathode materials, purchased more than 40 patents relating to high-nickel cathode material from Hanyang University, a private research university in Korea. Among them is a key “orientation patent” that allows the driving range of EVs to increase by 20 to 30 percent, based on the structural characteristic of cathode materials. These patents are widely recognized in the relevant industry as essential to produce high-nickel cathode materials and registered in many countries, including Korea, China, the U.S. and Europe.

With this licensing, LG Chem said it expects to promote the development of the battery material industry with other global cathode material suppliers. By doing so, the company expects to generate new sources of profits as the demand for technology to produce key battery materials, such as high-nickel cathode, is expected to rise. According to global marketing research firm SNE Research, the global cathode materials market is forecasted to grow 233% from $35.6 billion this year to $82.9 billion in 2030.
