The global supply of critical battery metals: lithium, nickel, and cobalt – is shaped by surging demand, geopolitical constraints, and production challenges, driven by the electric vehicle (EV) and renewable energy boom (Mining Technology, 2024). Demand for lithium is projected to grow sixfold by 2030, with nickel and cobalt rising 28-31 and 17-19 times by 2050, respectively, due to EV battery needs (McKinsey, 2024).
Supply concentration poses risks. Lithium production is dominated by Australia and Chile, nickel by Indonesia, and cobalt by the Democratic Republic of Congo (DRC), which supplies over 60% of global cobalt (McKinsey, 2024). Geopolitical issues, like DRC’s export pauses, disrupt cobalt supply, while Indonesia’s nickel ore export bans tighten global markets (Investing News, 2024).
Production challenges include high costs and long lead times for new mines – up to seven years – limiting rapid supply expansion (IEA, 2022). Low-grade ore mining increases costs as high-grade deposits deplete (IDTechEx, 2025). Refining, largely controlled by China, adds bottlenecks, with 60% of lithium and 80% of cobalt processed there (IEA, 2022).
Market volatility, with lithium prices dropping 75% in 2023, discourages investment, threatening future supply (S&P Global, 2023). Ethical concerns, particularly in DRC’s cobalt sector, push for recycling and cobalt-free batteries (Investing News, 2024). These factors demand diversified supply chains.
