Yonhap reported that South Korean steelmaker POSCO has broken ground for a plant that will produce sold-state electrolyte, a key component in solid-state batteries. The plant in Yangsan, about 420 kilometers southeast of Seoul, will be able to produce 24 tons annually from the second half of the year. SSE is one of the key components for future electric vehicle battery production, as it enables an EV to run a longer distance.Posco has been making efforts to boost its non-steel businesses, such as EV battery materials and hydrogen, amid stiff emission regulations. Early this month launched a holding company to better nurture non-steelmaking businesses. Posco will jack up its production capacity of cathode and anode materials used for batteries to 420,000 tons and 260,000 tons, respectively, by 2030. Its annual production of lithium and nickel will amount to 220,000 tons and 140,000 tons, respectively, by that year.
