South Korean company LG Chem has commenced the first-ever large-scale production of single-crystal high-nickel cathodes for advanced batteries. The manufacturing process began on June 26, 2023, at LG Chem’s cathode plant situated in Cheongju, approximately 75 miles (120 km) southwest of Seoul. The initial batches of these innovative battery materials are scheduled to be dispatched to global clients starting in July.
LG Chem, the parent company of battery manufacturer LG Energy Solution, emphasizes the significance of single-crystal cathodes, which are composed of individual particles containing various metals such as nickel, cobalt, and manganese. These cathodes play a pivotal role in next-generation batteries, as they have the potential to enhance battery lifespan by over 30% and increase capacity by 10% or more when compared to existing solutions.
Recognizing the anticipated high demand for these new cathode materials, LG Chem has already outlined plans for expanding the single-crystal high-nickel cathode production line at its Gumi plant, also situated in South Korea, by 2027. The projected annual production output will surpass 50,000 tons.
Although detailed specifications are not currently available, it can be estimated that this volume of production would be equivalent to that of a substantial battery gigafactory, or perhaps even multiple gigafactories if considering partial cathode content.
LG Chem elaborates that, initially, battery manufacturers are expected to blend the new single-crystal particles with conventional cathode materials, starting with a content ratio of 20% and gradually progressing towards 100%.
“In the initial phases, LG Chem will mix single-crystal cathode materials with conventional cathode materials in a ratio of 2:8, gradually transitioning to cathodes containing 100% single-crystals.”
An intriguing aspect is that these new cathode materials are anticipated to be utilized in the upcoming 4680-type cylindrical battery cells, despite their initial availability for pouch-type batteries:
“LG Chem will also expand the application of these cathode materials to next-generation batteries such as the 4680 cylindrical cells, which have external dimensions of 46 millimeters in diameter and 80 millimeters in height, as opposed to the existing pouch-type batteries.”
Shin Hak-cheol, CEO of LG Chem, expresses confidence in the game-changing potential of single-crystal high-nickel cathodes within the future battery material market, emphasizing their ability to address customer concerns. He affirms LG Chem’s commitment to leading the market through advanced battery material technology and a diversified product portfolio, with the ultimate aim of becoming the world’s largest integrated battery materials provider.
