Here we’ll delve into the battery minerals supply chain, the challenges it faces and potential solutions for a sustainable future.

Why Battery Minerals Matter

Battery minerals power the lithium-ion batteries in EVs, smartphones and grid storage systems. They’re essential for reducing our reliance on fossil fuels and supporting clean energy systems to combat climate change.

• Key Minerals:

• Lithium: In cathodes, for energy density.

• Cobalt: Battery chemistry stabilizer.

• Nickel: Battery energy storage.

• Graphite: In anodes, for battery life cycles.

Demand Surge: Global View

The International Energy Agency (IEA) says demand for lithium will grow over 40 times by 2040 if we hit net zero. Same for cobalt, nickel and other key minerals.

Battery Minerals Supply Chain Challenges

1. Geopolitical Concentration

Minerals are not evenly distributed, so the supply chain is vulnerable to geopolitical risk. For example:

• Lithium: Australia, Chile, China.

• Cobalt: 70% of global supply comes from DRC.

2. Environmental Impact

Mining and refining can cause huge environmental damage:

• Water depletion.

• Habitat destruction.

• Carbon-intensive refining.

The cobalt supply chain, dominated by DRC, is under fire for child labour and poor working conditions.

4. Infrastructure Bottlenecks

EV demand is growing faster than mining infrastructure. Building new mines or expanding existing ones takes years due to regulatory red tape.

5. Recycling and Circular Economy Constraints

Recycling is a solution to reduce mining dependency but it’s still in its infancy. Current methods only recover a small fraction of critical minerals.

Industry Responses and Solutions

1. Diversification of Supply Chains

Companies are looking to other countries to reduce dependence on a few.

Canada, the US, and Africa.

2. Technology

New tech to increase battery efficiency and reduce scarce materials:

• Solid-state batteries to replace lithium and cobalt.

• Sodium-ion for grid storage.

3. Recycling

Governments and industry are investing in recycling tech. For example:

• EU has mandated a recycling rate for battery materials by 2025.

• Redwood Materials is a startup working on lithium-ion recycling.

4. Sustainable Mining

Mining is being made more sustainable:

• Renewable energy in mining.

• Closed loop water systems.

Policy and Collaboration

Governments have a big role to play in the future of battery minerals:

• Incentivising Innovation: Subsidies for R&D in battery tech.

• Policy Frameworks: Policies for ethical and sustainable sourcing.

• Global Coordination: Collaboration through the G20 and the International Energy Agency.

What’s Next?

The battery minerals supply challenge is a big part of the clean energy transition. While it’s tough, so are the opportunities. By investing in technology, collaborating globally and prioritising sustainability we can meet the growing demand for battery minerals without compromising ethics or the environment.

As consumers and citizens, we have a part to play. Backing companies that put sustainability and ethics first can drive the industry to innovate responsibly.

By tackling the battery minerals supply challenge we can make the clean energy revolution as sustainable and fair as it’s big.
