Global battery demand across electric vehicle (EV) and storage applications rose to almost 1TWh in 2024, according to energy watchdog the IEA, in its latest report.
Demand was largely driven by EV sales growth, with EV battery demand growing by more than 25pc on the year to over 950GWh, mainly propelled by electric cars which accounted for over 85pc of EV battery demand, said the IEA in its EV Outlook 2025. The almost 1TWh of demand is expected to more than triple to over 3TWh in 2030 under the IEA's stated policies scenario (Steps), which is based on countries' prevailing policies , with more demand from electric trucks despite electric cars still making up the majority of demand.
EV battery demand rose by more than 30pc on the year in China, and currently takes up 59pc of total global EV battery demand. US demand has also grown, with the country taking up 13pc of the total share, on par with the EU. The IEA expects critical minerals supply surplus to persist over the next few years but cautioned that depressed prices could dissuade future investments and lead to supply shortages for lithium and nickel by 2030.
"It will take about a decade before recycling has a significant impact on reducing primary mineral demand," said the IEA, citing feedstock limitations. Recent raw material prices for battery recyclers in China, the largest battery recycling market, remain higher than their battery recycling yields such as recycled lithium, nickel and cobalt, a Chinese battery recycler told Argus. Domestic battery recycling plants operating rates are "not high," the battery recycler said, with very thin activity in the domestic black mass market.
Excessive battery capacity
Global battery cell manufacturing capacity grew by almost 30pc in 2024 to 3.3TWh, more than triple the battery demand, according to the report.
South Korean battery manufacturers accounted for over 400GWh of overseas battery manufacturing capacity in 2024, much higher than the 60GWh from Japanese manufacturers and 30GWh from Chinese manufacturers. South Korea's battery manufacturing is poised to further expand to more than 1TWh in 2030, almost double that of Chinese manufacturers, if all announced projects materialise.
Global manufacturing capacity could grow to about 6.5TWh in 2030, about double the demand projected under IEA's Steps scenario, if all committed projects are realised. This would also entail China's share of global manufacturing capacity weakening from 85pc in 2024 to two-thirds by 2030.
LFP battery share rises
Lithium-iron-phosphate (LFP) batteries made up nearly half of the global EV battery market in 2024, said the IEA.
Nearly all electric car LFP batteries sold in Europe or US were produced in China, which has a "de facto monopoly", said the IEA, with LFP becoming more attractive to European original equipment manufacturers looking to cut production costs.
South Korean battery makers' market share in the EU fell to 60pc last year, down from 80pc in 2022, displaced by Chinese battery producers because the chemistry of LFP makes it more competitive, according to IEA. But top South Korean battery makers — LG Energy Solution, Samsung SDI, SK On — have all unveiled plans to mass produce EV LFP batteries over the coming years, looking to compete in the space.
Japanese battery makers meanwhile saw their US market share fall to around 48pc, eroded by South Korea. South Korea took up 35pc of US market share last year, up from 20pc in 2022. Japanese domestic LFP development is also facing challenges, with Japanese carmaker Nissan recently cancelling a LFP plant in Kyushu as it goes through a restructure.
LFP's penetration in the southeast Asia, Brazil and India markets is rising even quicker, with LFP battery electric car shares surpassing 50pc in each of the countries in 2024, according to the report.
