As South Korean battery manufacturers officially launch mass production plans for lithium iron phosphate (LFP) batteries, Chinese battery companies are already prepared to make significant advances in the next-generation sodium-ion battery sector. This development is prompting South Korean firms to tighten their focus and accelerate research and development efforts. Some industry insiders express concern that China’s rapid expansion in the sodium-ion battery market could recreate the previous crisis faced by South Korean LFP battery producers.
