Hyundai and Kia have launched a project aimed at developing cheaper cathode materials for lithium iron phosphate batteries that could reduce reliance on Chinese battery suppliers. The project focuses on developing a new production process for LFP cathode material that eliminates the step of adding lithium to precursor materials like phosphate and iron sulfate. This new “direct synthesis” process would combine iron powder, phosphate, and lithium without the precursor step, resulting in cost savings and reduced emissions of hazardous substances. The development of this process in South Korea by South Korean companies could pave the way for greater LFP battery cell manufacturing in the country.
Hyundai’s announcement comes on the heels of a two-year joint venture to develop LFP batteries in South Korea as part of an effort to reduce dependence on Chinese battery suppliers. LFP battery technology originated in the U.S. but has been refined by various Chinese companies over the past two decades. LFP batteries are currently used in vehicles like the Tesla Model 3 and Ford Mustang Mach-E, offering advantages such as reduced dependency on nickel and cobalt, as well as decreased risk of overheating, thermal runaway, and heat-related degradation. While Chinese companies like BYD and CATL currently dominate LFP battery manufacturing, other automakers like Ford and General Motors are also exploring the use of LFP cells in their electric vehicles.
General Motors has confirmed that the next-generation Chevrolet Bolt EV, set to be released in 2025 as a 2026 model, will utilize LFP cells. This move could make the Bolt EV GM’s most affordable electric vehicle. Meanwhile, China continues to innovate on the LFP battery type, with companies like GAC introducing LFP cells with a 20% boost in energy density and CATL claiming to have developed next-generation LFP cells that can add 250 miles of range in just 10 minutes. The push for greater LFP battery production and innovation outside of China could provide automakers with more options for sourcing batteries, potentially reducing costs and emissions associated with battery manufacturing.
