Batteries typically accounts for 30% to 40% of the value of an electric vehicles (EV), and the race to net zero will focus attention on the security of supply of the critical minerals and metals needed to manufacture them.
Electric car sales continued to break records in 2021, testing the resilience of battery supply chains
Few areas in the world of clean energy are as dynamic as EV markets. In 2021, EV sales broke new records, with nearly 10% of global car sales being electric, four times their market share in 2019. Public and private spending on EVs doubled relative to 2020. More and more countries have pledged to phase out ICEs or have ambitious electrification targets. Five times more EV models were available in 2021 relative to 2015, and most major carmakers are announcing plans to further accelerate electrification of their fleets.
China accounted for half of the growth of the EV market in 2021. More vehicles were sold in China in 2021 (3.3 million) than in the entire world in 2020. Sales in Europe continued to grow robustly (up 65% to 2.3 million) after the 2020 boom, and they increased in the United States as well (to 630 000) after two years of decline. The first quarter of 2022 showed similar sales trends.
Today’s battery and minerals supply chains revolve around China
China produces three-quarters of all lithium-ion batteries and is home to 70% of production capacity for cathodes and 85% for anodes (both are key components of batteries). Over half of lithium, cobalt and graphite processing and refining capacity is located in China. Europe is responsible for over one-quarter of global EV assembly, but it is home to very little of the supply chain apart from cobalt processing at 20%. The United States has an even smaller role in the global EV battery supply chain, with only 10% of EV production and 7% of battery production capacity. Korea and Japan have considerable shares of the supply chain downstream of raw material processing, particularly in the highly technical production of cathode and anode material. Korea is responsible for 15% of global cathode material production capacity, while Japan accounts for 14% of cathode and 11% of anode material production. Korean and Japanese companies are also involved in the production of other battery components such as separators.
Most key minerals are mined in resource-rich countries such as Australia, Chile and the Democratic Republic of Congo, and handled by a few major companies. Governments in Europe and the United States have bold public sector initiatives to develop domestic battery supply chains, but the majority of the supply chain is likely to remain
Chinese through 2030. For example, 70% of battery production capacity announced for the period to 2030 is in China.
Battery and minerals supply chains will have to expand ten-fold to meet government EV ambitions
The rapid increase in EV sales during the pandemic tested the resilience of battery supply chains, and Russia’s war in Ukraine has further exacerbated matters with prices of raw materials such as cobalt, lithium and nickel surging. In May 2022, lithium prices were more than seven times higher than in early 2021 due to unprecedented battery demand and a lack of sufficient investment in new supply capacity. Meanwhile, Russia supplies 20% of global high-purity nickel. Average battery prices fell by 6% to USD 132 per kilowatt-hour in 2021, a slower decline than the 13% drop the previous year. If metal prices in 2022 remain as high as in the first quarter, battery packs would become 15% more expensive than they were in 2021, all else being equal. However, the relative competitiveness of EVs remains unaffected given the current oil price environment.
Pressure on the supply of critical materials will continue to mount as road transport electrification expands to meet net zero ambitions. Demand for EV batteries will increase from around 340 GWh today, to over 3500 GWh by 2030 in the Announced Pledges Scenario (APS). Cell components and their supply will also have to expand by the same amount. Additional investments are needed in the short-term, particularly in mining, where lead times are much longer than
for other parts of the supply chain – in some cases requiring more than a decade from initial feasibility studies to production, and then several more years to reach nominal production capacity. Projected mineral supply until the end of the 2020s is in line with the demand for EV batteries in the Stated Policies Scenario (STEPS). But the supply of some minerals such as lithium would need to rise by up to one-third by 2030 to satisfy the pledges and announcements for EV bateries in the APS. For example, demand for lithium – the commodity with the largest projected demand-supply gap – is projected to increase sixfold to 500 kilotonnes by 2030 in the APS, requiring the equivalent of 50 new average-sized mines.
There are other variables affecting demand for minerals. If current high commodity prices endure, cathode chemistries could shift towards less mineral-intensive options. For example, lithium iron phosphate cathode chemistry (LFP) does not require nickel nor cobalt, but comes with a lower energy density and is therefore better suited for shorter-range vehicles. LFP share of global EV battery supply has more than doubled since 2020 because of high mineral prices and technology innovation, primarily driven by an increasing uptake in China. Innovation in new chemistries, such as manganese-rich cathodes or even sodium-ion, could further reduce pressure on mining. Recycling can also reduce demand for minerals. Although the impact between now and 2030 is likely to be small, recycling’s contribution to moderating mineral demand is critical after 2030. In the Net Zero Emissions by 2050 Scenario (NZE), demand grows even faster, requiring additional demand-side measures and technology innovation. Today’s corporate and consumer preferrence for large car models such as sports utility vehicles (SUVs), which account for half of all electric models available globally and require larger batteries to travel the same distances, is exerting additional pressure.
Ensuring secure, resilient and sustainable EV supply chains will be key to accelerating global uptake
Electrifying road transport requires a wide range of raw materials. While all stages of the supply chain must scale up, extraction and processing are particularly critical due to long lead times. Governments must leverage private investment in sustainable mining and ensure clear and rapid permitting procedures to avoid potential supply bottlenecks.
Innovation and alternative chemistries that require smaller quantities of critical minerals, as well as extensive battery recycling, can ease demand pressure and avoid bottlenecks. Incentivising battery “rightsizing” and the adoption of smaller cars can also decrease demand for critical metals.
Governments should strengthen cooperation between producer and consumer countries to facilitate investment, promote environmentally and socially sustainable practices, and encourage knowledge sharing. Governments should ensure traceability of key EV components and monitor progress of ambitious environmental and social development goals at every stage of battery and EV supply chains.
