Battery Circular Economy: Transforming the Industry by 2045

What is a Battery Circular Economy?

A battery circular economy represents a transformative approach to managing the complete lifecycle of batteries, fundamentally shifting away from the traditional linear "take-make-dispose" model toward a sustainable "reduce-reuse-recycle" paradigm. This holistic framework integrates sustainability principles throughout the entire battery value chain, from initial design through end-of-life management.

At its core, the battery circular economy aims to maximize resource efficiency while minimizing environmental impact. According to the United Nations Environment Programme, "A circular economy for batteries minimizes resource extraction through reuse, remanufacturing, and recycling" (UNEP, 2023). This approach becomes increasingly critical as global demand for battery metals investment landscape continues its exponential growth trajectory.

Definition and Core Principles

The battery circular economy operates on several interconnected principles:

• Resource conservation: Minimizing the extraction of virgin materials by keeping existing resources in use for as long as possible
• Lifecycle optimization: Extending battery lifespans through improved design, maintenance, and repurposing
• Waste elimination: Developing systems that capture materials at end-of-life for regeneration into new products
• Value retention: Preserving the economic value of materials through multiple lifecycle phases
• System-wide innovation: Redesigning products, processes, and business models to facilitate circularity

This systemic approach acknowledges that batteries don't exist in isolation but as part of broader energy, transportation, and manufacturing ecosystems.

Why Battery Circularity Matters

The transition to a battery circular economy addresses multiple pressing challenges facing the energy storage sector:

Resource scarcity concerns: The International Energy Agency projects that mineral demand for electric vehicle batteries could increase by 30 times by 2040 under net-zero scenarios (IEA, 2024). Current production and reserves of critical minerals energy transition like lithium, cobalt, and nickel cannot sustainably meet this demand through primary extraction alone.

Environmental protection: Traditional battery manufacturing and disposal processes create significant environmental burdens:

• Mining operations can cause habitat destruction, water pollution, and greenhouse gas emissions
• Improper disposal leads to toxic material leaching and lost resource recovery opportunities
• Carbon-intensive production contributes to climate change

Economic opportunity: The battery circular economy creates diverse business opportunities:

• New value streams from material recovery and repurposing
• Innovative service models like battery-as-a-service
• Job creation across collection, refurbishment, and recycling sectors
• Reduced supply chain vulnerabilities and price volatility

Energy transition enablement: By ensuring sustainable battery supply chains, the circular economy supports the broader transition to renewable energy systems that depend on reliable energy storage solutions.

"The circular economy approach isn't just an environmental necessity—it's becoming an economic imperative as battery demand outpaces mineral supply capabilities. Companies implementing circular principles today are positioning themselves for competitive advantage in tomorrow's resource-constrained world."

The battery circular economy represents a fundamental reconceptualization of how we design, produce, use, and manage batteries. Rather than treating them as disposable products, this approach recognizes batteries as valuable material banks that can provide multiple service lives through innovative business models and technical solutions.

How Will the Battery Industry Transform by 2045?

The battery industry stands at the cusp of a revolutionary transformation that will fundamentally reshape its resource dependencies, manufacturing processes, and business models over the next two decades. This evolution represents one of the most significant industrial pivots of the 21st century, driven by both environmental necessity and economic opportunity.

CATL's Bold Vision for Resource Independence

In a landmark announcement during London Climate Action Week, Jiang Li, Deputy General Manager and Board Secretary of CATL, made a striking prediction about the future of battery production: "In the next 20 years, 50% of new battery production globally will no longer rely on mining" (SMM, 2025).

This ambitious vision—targeting the year 2045—represents a radical departure from the industry's current heavy dependence on primary mineral extraction. To contextualize the magnitude of this transformation, consider that today less than 5% of lithium-ion batteries globally are recycled (IEA, 2024), with the vast majority of raw materials coming from mining operations.

CATL's projection envisions a systemic shift where half of all new batteries would be manufactured using:

• Recycled materials recovered from end-of-life batteries
• Regenerated components from second-life applications
• Alternative material sources beyond conventional mining
• Extended-use batteries with significantly longer lifespans

According to Jiang Li, this transformation will "drive a systematic transformation of the energy system towards efficiency, low carbon, and sustainability" (SMM, 2025). The implications for global supply chains, manufacturing processes, and business models are profound.

The Ellen MacArthur Foundation Partnership

To advance this transformative vision, CATL has partnered with the Ellen MacArthur Foundation (EMF) to develop the "Global Energy Circularity Program." This collaboration brings together one of the world's largest battery manufacturers with the leading global authority on circular economy principles.

Jonquil Hackenberg, CEO of the Ellen MacArthur Foundation, emphasized the significance of this initiative: "The release of this vision marks a new stage where the battery circular economy is moving from concept to systematic practice" (SMM, 2025).

The partnership will focus on:

1. Creating actionable frameworks for implementing circular economy principles throughout the battery value chain
2. Developing replicable models that can be adapted across different regions and markets
3. Establishing industry benchmarks for circularity performance
4. Building cross-sector collaborations to accelerate the transition

The program recognizes that achieving 50% mining independence will require coordinated action across multiple stakeholders, including manufacturers, recyclers, policymakers, and consumers. It will explore "transformation paths for different countries and regions" (SMM, 2025), acknowledging that implementation strategies must adapt to local conditions and existing infrastructure.

This partnership signals that battery circularity is moving beyond theoretical discussions into the realm of practical implementation at industrial scale. By bringing together CATL's manufacturing expertise with EMF's circular economy frameworks, the collaboration aims to catalyze industry-wide transformation and establish new standards for sustainable battery production.

"The battery industry's transformation represents a microcosm of the broader shift required in our global economy—from extractive and wasteful to regenerative and resource-efficient. The companies that lead this transition will define the next generation of energy storage."

What Are the Four Pillars of Battery Circularity?

The CATL-Ellen MacArthur Foundation "Global Energy Circularity Program" establishes four fundamental pillars that form the structural framework for transforming the battery industry. These interconnected pillars address the complete lifecycle of batteries and create a comprehensive roadmap for implementing circular economy principles across the entire value chain.

Transforming the Value Chain System

The first pillar focuses on reimagining the entire battery value chain as an integrated system optimized for sustainability rather than a linear sequence of extraction, production, use, and disposal.

Key components include:

• Low-carbon development: Systematically reducing carbon emissions at each stage of battery production and use
• Efficiency optimization: Minimizing energy and material inputs while maximizing performance outputs
• Resource circulation: Creating closed-loop material flows that reduce dependence on virgin resources
• Sustainable sourcing: Implementing responsible procurement practices for any remaining primary materials
• Transparent tracking: Deploying digital solutions to monitor material flows and verify sustainability claims

This systemic approach recognizes that achieving circularity requires fundamental changes to how the entire battery ecosystem operates, not just end-of-life management. It aims to integrate sustainability metrics into every decision point across supply chain management.

Reimagining Product Design

The second pillar acknowledges that circularity must be designed into batteries from inception—not treated as an afterthought. CATL emphasizes creating batteries that are "durable, easily disassembled, recyclable, and second-life applicable" (SMM, 2025).

Central design principles include:

• Modular architecture: Designing batteries with standardized components that can be easily replaced, upgraded, or separated for recycling
• "Easy disassembly first": Prioritizing designs that facilitate efficient disassembly at end-of-life, reducing recycling costs and improving material recovery rates
• Durability enhancement: Extending useful lifespans through improved thermal management, better materials, and advanced battery management systems
• Second-life compatibility: Ensuring batteries can be repurposed for less demanding applications after their primary use
• Material selection: Choosing materials based on both performance and recyclability criteria

This design-centered approach represents a significant shift from current practices, where many batteries are designed primarily for performance and cost with limited consideration for end-of-life management. By embedding circular principles into product architecture, manufacturers can dramatically improve resource efficiency throughout the battery lifecycle.

Developing New Business Models

The third pillar moves beyond physical product improvements to reimagine how batteries create and deliver value in the marketplace. This involves a paradigm shift from traditional ownership models toward service-based approaches.

Innovative business models include:

• Battery-as-a-service: Manufacturers retain ownership of batteries and sell energy storage as a service, incentivizing longevity and recyclability
• Battery swapping infrastructure: Enabling rapid exchange of depleted batteries for charged ones, improving user experience while facilitating maintenance and recycling
• Battery bank systems: Aggregating batteries to provide grid-scale services, maximizing utilization and creating value beyond single applications
• Shared fleet solutions: Optimizing battery deployment across multiple users to increase utilization rates and total lifecycle value

CATL emphasizes the importance of "shared services (swapping, banks, fleets)" (SMM, 2025) in maximizing battery utilization and value creation. These models fundamentally change the relationship between manufacturers, users, and batteries—creating aligned incentives for longevity and circularity.

Enhancing Recycling Systems

The fourth pillar focuses on developing robust systems to recover, process, and reuse materials from end-of-life batteries. This is essential to achieving the goal of 50% mining independence by 2045.

Key recycling system elements include:

• Large-scale recycling infrastructure: Building industrial-scale facilities capable of processing growing battery volumes
• Advanced recovery technologies: Implementing processes that achieve high recovery rates for critical materials
• Closed-loop systems: Creating direct pathways to return recovered materials to battery manufacturing
• Standardized processes: Developing consistent approaches to ensure quality and efficiency
• Collection networks: Building comprehensive systems to gather end-of-life batteries from diverse sources

Effective recycling closes the material loop, transforming end-of-life batteries from potential waste into valuable material sources for new production. By focusing on efficiency and scale, recycling systems can progressively reduce the battery industry's dependence on primary mineral resources.

Together, these four pillars create a comprehensive framework for transforming the battery industry from a linear model to a circular one. Their implementation requires coordinated action across multiple stakeholders, from designers and manufacturers to users and recyclers. The CATL-EMF program provides a structured approach to this complex transformation, addressing both technical and business challenges.

What Economic Opportunities Does Battery Circularity Create?

The transition to a battery circular economy isn't just an environmental imperative—it represents one of the most significant economic opportunities in the global energy transition. As the industry transforms its practices and business models, substantial new markets and revenue streams are emerging across the entire value chain.

Market Growth Projections

According to CATL's projections, the global battery recycling market alone is expected to exceed 1.2 trillion yuan (approximately $170 billion USD) by 2040 (SMM, 2025). This represents a massive new economic sector that barely exists today, with current battery recycling markets valued at less than $5 billion globally.

This growth will be driven by several converging factors:

• Exponential increase in battery volumes: As electric vehicle adoption accelerates and energy storage deployments expand, the sheer quantity of batteries reaching end-of-life will grow dramatically
• Rising material values: As demand for battery materials continues to outpace primary supply, the economic value of recovered materials will increase
• Technology improvements: Advances in recycling efficiency will improve cost-effectiveness and material recovery rates
• Regulatory requirements: Expanding producer responsibility regulations will create compliance-driven market demand

Beyond the recycling market, the battery circular economy will create significant job opportunities. CATL estimates that circular battery value chains will create "over 10 million jobs" globally (SMM, 2025). These employment opportunities will span multiple sectors:

• Collection and logistics: Jobs in gathering, sorting, and transporting end-of-life batteries
• Refurbishment and remanufacturing: Technical roles in testing, repairing, and repurposing batteries
• Recycling operations: Positions in processing, material recovery, and quality control
• Circular design and engineering: Roles focused on designing products and systems for circularity
• Circular business model implementation: Jobs in service-based battery offerings and management

The European Commission estimates that the circular economy will create approximately 800,000 jobs in the EU alone by 2030, with battery-related sectors representing a significant portion of this growth (European Commission, 2023).

Business Innovation Opportunities

The battery circular economy is catalyzing the development of entirely new business models and value propositions. Companies are discovering innovative ways to create and capture value beyond traditional manufacturing and sales approaches.

As Jiang Li of CATL notes, "The circular economy will unlock new economic opportunities and social value" (SMM, 2025). These opportunities extend beyond direct revenue from recycled materials to include entirely new value propositions built around lifecycle services, performance guarantees, and resource optimization.

"The battery circular economy represents a classic case of environmental and economic interests aligning. By keeping materials in productive use longer and reducing dependence on volatile raw material markets, companies can simultaneously improve environmental performance and build more resilient business models."

The economic potential of the battery circular economy extends beyond simple cost savings or compliance requirements. It represents a fundamental reconfiguration of how value is created and captured in the energy storage sector—creating opportunities for both established players and innovative startups to develop sustainable competitive advantages.

How Are Companies Implementing Battery Circularity Today?

While the vision for a fully circular battery economy extends decades into the future, leading companies are already taking concrete steps to implement circular principles in their operations today. These early implementations provide valuable insights into effective approaches and potential challenges.

Current Industry Leaders and Initiatives

CATL has positioned itself at the forefront of the battery circular economy movement through its systematic research and development efforts. The company is "conducting systematic research on battery circular economy" and has formalized this commitment through its partnership with the Ellen MacArthur Foundation (SMM, 2025).

This collaboration is exploring "replicable and scalable circular solutions for global energy transformation" and developing specific "transformation paths for different countries and regions" (SMM, 2025). This recognition of regional differences acknowledges that circular economy implementation must adapt to local conditions, including:

• Existing manufacturing infrastructure
