Exporting Used EVs Halves Lithium-ion Battery Recovery Potential

A significant portion of electric vehicle lithium-ion batteries are lost to domestic recycling streams due to the export of used vehicles, drastically reducing the potential for material recovery.

01

Key Findings

  • 01Approximately 76.5% of used electric vehicles were exported, significantly limiting the domestic availability of lithium-ion batteries for recycling.
  • 02Recovery rates for key battery materials varied widely, with manganese showing a near-zero recovery rate due to economic impracticality.
  • 03Losses of valuable materials occurred through incineration and wastewater discharge.

Application

Design takeaway

Designers must account for the global movement of products and their components in their lifecycle planning, as export markets can significantly disrupt domestic resource recovery efforts.

How to apply

When designing products with valuable or critical materials, investigate the typical end-of-life pathways in your target markets, including export potential, and assess how these pathways impact the feasibility of material recovery and circularity.

Project actions

  • 01Consider the global supply chain and disposal routes for your product.
  • 02Investigate the economic feasibility of recovering different materials from your product's components.
  • 03Research policies related to product end-of-life management in your target market.

Method & Evidence

AimWhat is the material flow of electric vehicle lithium-ion batteries within a national context, and how do current disposal and export practices affect the potential for material recovery and recycling?
MethodMaterial Flow Analysis (MFA) and Substance Flow Analysis (SFA)
ProcedureThe study conducted a mass-based Material Flow Analysis and a Substance Flow Analysis for electric vehicle lithium-ion batteries. It mapped 33 systems and 170 flows across manufacturing, consumption, discharge/collection, and treatment stages, utilizing national statistics and data from commercial facilities. Specific attention was paid to the recovery rates of key elements like nickel, cobalt, manganese, and lithium.
ContextElectric Vehicle (EV) Lithium-ion Battery (LIB) lifecycle management in the Republic of Korea.

Variables

IV["Export rate of used electric vehicles","Economic viability of material recovery"]
DV["Domestic lithium-ion battery recovery rate","Material recovery rates (Ni, Co, Mn, Li)"]
CV["National statistics on EV sales and battery replacements","Data from commercial facilities","Material composition of LIBs"]

Strengths & Limitations

Strengths

  • +Comprehensive material flow analysis covering multiple stages of the battery lifecycle.
  • +Inclusion of both mass-based and substance-based analysis for detailed insights.

Limitations

The study is specific to one country's data. The economic viability of recycling can change rapidly with market fluctuations.

Reliability & validity

The reliability of the findings depends on the accuracy and completeness of the national statistics and commercial facility data used. The validity is strengthened by using both MFA and SFA, but the economic assumptions for material recovery might be a point of contention.

Think critically

If a product is designed for maximum recyclability, but the majority of used products are exported, does the initial design for recyclability still hold significant value in its original market?

05

Design Principles

"Design for circularity must consider geopolitical and economic factors that influence material recovery pathways."

Understanding material flows within product lifecycles is crucial for developing effective resource management strategies. This insight highlights how international trade and disposal practices can directly impact the availability of valuable materials for recycling, influencing supply chain sustainability and the feasibility of circular economy models.

06

What This Means for Your Design

When electric cars are sold as used in other countries, their batteries can't be recycled at home, meaning we lose out on valuable materials.

How to use in your project

  • 1.Use this study to justify the importance of considering global material flows and export markets in your design project's lifecycle assessment.
  • 2.Reference the findings on material recovery rates to highlight potential challenges and opportunities for your chosen materials.

Paragraph starter

The material flow analysis of electric vehicle lithium-ion batteries reveals that a significant portion of these valuable components are lost to domestic recycling streams due to the export of used vehicles (approximately 76.5% in the Republic of Korea). This highlights a critical challenge in achieving circularity, as international trade practices can severely limit the availability of materials for recovery, underscoring the need for design strategies that account for global end-of-life pathways and economic recovery constraints.
