印尼镍矿出口禁令引发全球电池产业链震荡
When Indonesia abruptly halted the export of unprocessed nickel ore in January 2020, the decision was met with a mixture of disbelief and derision in international commodity markets. The archipelago had long been the world’s largest supplier of the silvery metal, feeding stainless steel mills from China to Germany with ore dug from the rainforests of Sulawesi and Halmahera. By forcing miners to build smelters and refineries on Indonesian soil, or lose access entirely, Jakarta was wagering that it could leapfrog from raw-material supplier to a vital hub in the electric-vehicle supply chain. Three years on, that wager is already reshaping global battery chemistry, drawing tens of billions of dollars in foreign investment, and triggering a furious debate over the environmental and social costs of rapid industrial transformation.
The logic behind the ban is not without precedent. For decades, resource-rich nations have watched their minerals depart in bulk carriers, only to return as high-value manufactured goods. The Indonesian government, emboldened by the success of a partial ban imposed in 2014, calculated that the global race for battery-grade nickel—an essential ingredient for the lithium-ion cells powering everything from Teslas to grid storage—gave it unprecedented leverage. Multinational conglomerates, facing an insatiable demand forecast, duly signed memorandums for sprawling industrial parks where laterite ore is dissolved in acid under high pressure, yielding mixed hydroxide precipitate destined for cathode plants. By late 2022, Indonesian nickel production had more than doubled from pre-ban levels, and the country had become the world’s second-largest producer of nickel chemicals, trailing only China.
