Summary of "Prospects for electric vehicle batteries in a circular economy"

Core Content

This report by Eleanor Drabik and Vasileios Rizos explores the potential impacts of managing electric vehicle (EV) lithium-ion batteries within a circular economy framework in the European Union (EU). The focus is on how increased collection and recycling efficiency can benefit the EU economically, environmentally and socially.

Main Viewpoints

• Economic Benefits:

  • Higher collection and recycling rates can reduce dependence on imported materials and retain value within the EU.
  • By 2030, €408 million could be recovered from key materials (cobalt, nickel, aluminium, lithium) under a less ambitious scenario, and €555 million under a more ambitious one.
  • By 2040, these values could rise to €1.9 billion and €2.6 billion respectively.

• Environmental Benefits:

  • Recycling can significantly reduce CO₂ emissions. Under scenario 2, over 1 million tonnes of CO₂-equivalent could be saved by 2040, equivalent to the annual emissions of two primary aluminium smelters.
  • Recycling aluminium is particularly beneficial due to its lower energy requirements compared to primary production, which leads to substantial CO₂ reductions.

• Social Benefits:

  • Increased recycling activities could create jobs in the EU, especially in the recycling and dismantling sectors.
  • The development of a circular battery economy may lead to a more sustainable and resilient supply chain.

Key Information

2.1 Sales and Price Trends

• EV sales are expected to grow significantly, from 1 million in 2017 to 24.4 million by 2030.
• The EV battery market is projected to grow from 21 GWh in 2016 to 1,300 GWh by 2030.
• Battery prices have been declining steadily over the past five years, with projections of further drops to as low as €60–75 per kWh by 2030.

2.2 Technological Developments

• Lithium-ion batteries have seen improvements in energy density, price, environmental impact and endurance.
• There is a shift towards using less cobalt and more nickel in battery chemistries, especially in NMC and NCA types.
• The NMC811 battery chemistry, which contains more nickel and less cobalt, is becoming more prevalent.

2.3 Battery Value Chain

• The value chain includes mining, processing, cell manufacturing, battery pack manufacturing, EV manufacturing, and recycling.
• China dominates cell manufacturing and processing, while the EU is a major producer of EVs.
• The EU is not yet equipped to manage a large number of end-of-life batteries, despite strong legislative requirements.

2.4 Key Raw Materials

• Cobalt:

  • A critical raw material (CRM) due to its high economic importance and vulnerability to supply disruptions.
  • Mainly sourced from the Democratic Republic of Congo (DRC), with 51% of global production linked to copper and nickel mining.
  • High demand and price volatility make it a key material for recycling.

• Nickel:

  • A major component in lithium-ion cathodes, especially in NCA and NMC batteries.
  • Demand is expected to increase significantly with the growth of the EV market.
  • Prices have declined since 2010 but are expected to rise again due to increased usage.

• Aluminium:

  • Used extensively in battery casings and vehicle components.
  • Recycling offers significant energy and CO₂ savings.
  • The EU is a net importer of primary aluminium, but recycling can help reduce reliance on imports.

• Lithium:

  • Essential for EV traction batteries.
  • Demand is projected to triple by 2025.
  • Although technically feasible, lithium recycling is not yet economically viable due to high costs and volatile prices.

Scenario Development

3.1 Methodology

• The study uses two ex-ante scenarios to assess the potential impacts of collection and recycling rates.
• Scenario 1 represents a less ambitious approach, while Scenario 2 is more ambitious and highlights greater benefits.

3.2 Assumptions

• Collection/Take-back Rates:
  • Scenario 1 assumes lower rates, while Scenario 2 assumes higher rates.
• Recycling Efficiency Rates:
  • Scenario 2 assumes higher efficiency in material recovery.
• Second-life Rates:
  • Considered between EV manufacturing and recycling.
• CO₂ Emissions:
  • Scenario 2 shows significant reductions in emissions compared to Scenario 1.

3.3 Building the Scenarios

• Scenario 1:
  • Expected to recover €408 million in 2030 and €1.9 billion in 2040 from key materials.
• Scenario 2:
  • More ambitious, with higher collection and recycling rates.
  • Expected to recover €555 million in 2030 and €2.6 billion in 2040.
  • In 2030, Scenario 2 could recover 4,058 tonnes of cobalt worth €295 million, which is 41% of EU cobalt imports in 2012.
  • In 2040, Scenario 2 could recover 18,763 tonnes of cobalt worth €1.37 billion.

Impacts

4.1 Trade

• Recycling materials within lithium-ion batteries can reduce reliance on imports and improve the EU's trade balance.
• The study highlights the trade implications of recovering key materials like cobalt, nickel, aluminium and lithium.

4.2 Investment and Employment

• Increased recycling efforts can create jobs in the EU, particularly in the collection, dismantling and recycling of EV batteries.
• The study suggests that investment in recycling infrastructure is necessary to achieve the benefits of a circular economy.

4.3 Environment

• Recycling can significantly reduce CO₂ emissions and other environmental impacts.
• The study emphasizes the importance of developing efficient recycling processes to support sustainability goals.

Policies

5.1 The Batteries Directive

• The EU has been working on legislation to support the development of a circular battery economy.
• Policies are being developed to ensure that the EU can manage the growing number of end-of-life batteries.

5.2 Extended Producer Responsibility (EPR)

• EPR schemes are being promoted to encourage manufacturers to take responsibility for the recycling of their products.
• These schemes can help increase recycling rates and reduce waste.

5.3 Rules for Second-life

• Second-life applications for EV batteries are an important part of the circular economy.
• These applications should be considered in the value chain and could provide additional economic and environmental benefits.

5.4 Ecodesign

• Ecodesign regulations are being developed to promote sustainable battery production and use.
• These regulations can help reduce the environmental impact of battery manufacturing and use.

Summary and Conclusions

• Increasing collection and recycling efficiency rates of EV batteries in the EU can reduce dependence on imported materials and retain value within the EU economy.
• The study recommends strengthening research and innovation (R&I) in lithium-ion battery recycling to improve cost-effectiveness and efficiency.
• More research is needed to evaluate the costs of recycling, the level of investment required, and the net impact on employment.
• The development of a circular economy for EV batteries is crucial for achieving sustainability and economic resilience in the EU.
