Application

Design takeaway

Integrate strategies for battery repurposing and recycling into the design process to create more sustainable and resource-efficient energy storage solutions.

How to apply

When designing energy storage systems, research the availability and condition of retired EV batteries in your region and explore partnerships with battery repurposing or recycling facilities.

Project actions

01Consider the environmental impact of materials used in your design.
02Investigate opportunities for product longevity and end-of-life management.

Method & Evidence

AimTo investigate the potential for repurposing post-vehicle-application lithium-ion batteries for stationary energy storage and its impact on new battery manufacturing needs.

MethodMathematical modelling and simulation, coupled with a practical demonstration.

ProcedureA mathematical model was developed to forecast the manufacturing capacity required for battery remanufacturing, repurposing, and recycling. This model was simulated under various scenarios. A demonstration of repurposing was conducted, using retired batteries to power a semi-portable solar-powered recycling platform.

ContextElectric vehicle battery lifecycle management and stationary energy storage solutions.

Variables

IVBattery repurposing strategy (repurposing vs. new manufacturing).

DVManufacturing capacity needed for new batteries.

CVBattery type, energy demand scenarios, recycling process parameters.

Strengths & Limitations

Strengths

+Addresses a critical emerging issue in sustainable energy.
+Combines theoretical modelling with practical demonstration.

Limitations

Access to retired batteries can be difficult. Testing the full performance and safety of repurposed batteries requires specialized equipment and knowledge.

Reliability & validity

The reliability of the mathematical model depends on the accuracy of its input parameters and assumptions. The demonstration's validity is limited by its scale and specific setup.

Think critically

Beyond the environmental benefits, what are the economic and logistical challenges of establishing widespread battery repurposing infrastructure?

Design Principles

"Design for Disassembly and Reuse: Products should be designed with their end-of-life in mind, facilitating the recovery and reuse of components and materials."

As the adoption of electric vehicles grows, managing end-of-life batteries becomes a critical design challenge. Repurposing offers a sustainable pathway to extend battery life and reduce the environmental impact and resource depletion associated with manufacturing new batteries.

What This Means for Your Design

Old electric car batteries can be used again for things like storing solar power, which means we don't need to make as many new batteries.
