LG Chem starts mass production of single crystal cathodes
3. August 2023South Korea’s LG Chem Ltd announced in late June that it has begun mass production of the next generation of a new cathode material with a high nickel content. The material consists of a single crystal structure and is designed to boost the performance of EV batteries. The first shipment of the single crystal cathodes from the Cheongju plant to customers is scheduled to begin in July, the chemical company wrote in a press release. LG Chem’s Cheongju site is located 112 kilometres south of Seoul. In addition, LG Chem plans to expand single-crystal cathode production at its Gumi plant in the southeast of the country with a capacity of 50,000 tonnes annually. For battery related products, KC certification, KCs certification or other Korean product certification is often required to be approved for the Korean market.
The single crystal cathode material consists of different metals such as nickel, cobalt and manganese in a single component. It is considered a key component for extending the life and capacity of the next generation of batteries. Cathodes are the main element of lithium-ion batteries and account for 40 per cent of production costs. Conventional cathodes have a polycrystalline structure consisting of a collection of tiny metal particles that often crack during charging. These cracks can lead to the formation of gases in the battery and shorten the battery’s life. Single-crystal cathodes increase the energy density of a battery and could boost the performance of EVs by up to 10 per cent, according to LG Chem. The single-crystal cathodes are installed in pouch-shaped and round cells, including LG’s next-generation 4680 batteries.
