South Korean battery makers could raise prices by 30 percent to 40 percent to offset high commodity costs and they are in talks with electric vehicle makers over new long-term contracts, according to SNE Research.
“We had a meeting with Korean cell makers recently that led us to adjust the outlook for prices of electric-car batteries,” SNE Executive Vice President James Oh said at a seminar Wednesday. “They say battery prices are highly likely to rise by 2024 or 2025.”
While the companies didn’t disclose how much they might increase prices by, those using lithium, nickel, cobalt and manganese could lift prices of battery packs as much as 40 percent by 2025, Oh told Bloomberg News on the sidelines of the event.
Last year, the average lithium-ion battery pack for an EV was between $147 and $153 per kilowatt hour, according to SNE Research. Batteries account for about 30 percent to 40 percent of the price of an EV.
Rising lithium prices are also affecting solid-state-batteries that use sulfide electrolytes, LG Energy Solution Vice President Jay Kim said at Wednesday’s seminar in Seoul.
“Sulfide-electrolyte-based solid-state batteries are extremely expensive compared to other types of solid-state batteries and need a lot of lithium,” Kim said. “Prices of sulfide electrolyte could double from last year’s level.”
With labs in South Korea and the U.S., LG is working on commercializing sulfide-electrolyte-based solid-state cells by 2030, Kim said.
Global automakers are pushing Korean battery partners to change to prismatic-shape cells from pouch-type ones being produced now, as they believe they are safer, Oh said.
Volkswagen Group is among them, and its partner, SK On, is likely to announce a prismatic plan soon, he said. Samsung SDI is the only South Korean battery maker with the technology for manufacturing the cells.
“You need to be a bit careful with handling pouch-type cells, which have a higher possibility of swelling than prismatic ones,” Samsung SDI Vice President Lee Tae Kyung said during a presentation on battery safety.
