Abstract

:
In response to escalating environmental concerns and the imperative for a transition to a more sustainable economy, the European Union enacted a new regulation on the electric battery market in July 2023. This regulation integrates the principles of the circular economy, as outlined in the European Green Deal, addressing all phases of the battery life cycle, including the mining of raw materials, product design, production processes, reuse, and recycling. In light of this development, the principal manufacturers of electric vehicles (EVs) and hybrid electric vehicles (HEVs) have undertaken various circular economy (CE) and life cycle (LC) strategies. Their objective is to align their operations with these new regulatory requirements and enhance their sustainability credentials. The global automotive industry, encompassing thousands of entities with an annual turnover exceeding USD 3 trillion, is a significant economic sector. Within this industry, it is estimated that more than 50 manufacturers are involved in the production of EVs, ranging from established automakers to emerging startups. This study applies content analysis to obtain qualitative and quantitative information from data disclosed by companies and organizations, with a specific focus on entities that currently feature EVs or HEVs. The methodology involves examining publicly available reports and corporate disclosures to assess industry trends and regulatory compliance. For this purpose, the analysis selected the 10 largest EV manufacturers in the world, based on sales reports provided by the manufacturers themselves and their respective market shares, as reported by automotive news portals and blogs. The evaluation of their actions was derived from the annual sustainability reports of these companies, with the aim of identifying the practices already implemented and their anticipated contributions to extending battery life and minimizing environmental impact.

1. Introduction

The evolution of storage batteries for electric vehicles has been one of the industry’s main challenges, particularly regarding stability and energy efficiency in extended cycles. Recent studies on solid-state batteries have demonstrated promising advances in improving the interface between the electrode and the electrolyte, reducing contact losses and increasing ionic conduction efficiency. Lyu et al. [1] developed a pre-grafted solid polymer electrolyte (PGSPE), which forms a permeable, void-free interface between the electrode and the electrolyte during charge and discharge cycles. This advancement significantly enhances the stability of potassium- and lithium-ion batteries at high voltages, enabling stable cycles beyond 2000 cycles at 4.5 V and over 500 cycles at 4.6 V, with high Coulombic efficiency. The adoption of such technologies could represent a milestone in extending the lifespan of electric vehicle batteries, aligning with circular economy strategies by minimizing degradation and the need for new material extraction [1].
The global electric vehicle (EV) and hybrid electric vehicle (HEV) market has experienced significant growth in recent years. This surge is attributable to technological advancements, stricter environmental regulations, and government incentives. In 2022, global electric vehicle sales reached 10.5 million units, representing 14% of new car sales, with global revenue exceeding USD 425 billion [2]. By 2023, sales had increased further, with an estimated 14 million units sold, accounting for approximately 18% of global car sales. This reflects a 35% growth compared to the previous year [3], underscoring the impact of incentive policies and the rising demand for vehicles with lower environmental impacts. Currently, the global automotive sector includes approximately 50 major EV and HEV manufacturers among more than 200 active automakers worldwide [3]. However, about 15 companies, including giants like Tesla, BYD, and Volkswagen, lead the development and production of electric vehicles and dominate the market [4].
The total number of EVs on global roads has reached 40 million units, marking a significant milestone in the electrification of the automotive sector [3]. This achievement has been driven primarily by markets in China, Europe, and the United States, which together account for nearly 95% of global electric vehicle sales [5]. Specifically, China was responsible for approximately 60% of global sales, with over 8 million new electric vehicle registrations in 2023 [6]. In Europe, nearly 3.2 million new registrations were recorded, and in the United States, sales grew by more than 40% compared to 2022, with 1.4 million electric vehicles sold [3].
The circular economy (CE) plays a vital role in strengthening sustainability in the automotive sector, especially in the management of electric vehicle batteries. The CE proposes a closed cycle in which materials are reused, recycled, and remanufactured, reducing dependence on virgin raw substances such as lithium and cobalt, which have significant environmental and social impacts [7]. The companies featured in this study adopt battery remanufacturing practices, providing a ’second life’ to these components in energy storage systems. The repurposing of EV batteries for stationary applications presents significant environmental benefits when analyzed from a life cycle perspective [8]. After their use in EVs, these batteries retain approximately 80% of their storage capacity, making them suitable for reuse in energy systems with lower demand. This secondary use extends the battery’s life cycle, reducing the need for raw material extraction and mitigating the environmental impact associated with the production of new batteries [9]. This approach extends the useful life of batteries and minimizes their environmental impact.
Life cycle assessment (LCA) is critical for understanding and mitigating environmental impacts across all stages of the battery life cycle. It enables companies to identify key areas of energy consumption and carbon emissions, from raw material extraction to end-of-life disposal [10]. Recent studies have highlighted that lithium-ion battery production contributes significantly to carbon emissions. Therefore, recycling and material reuse are essential for enhancing the sector’s sustainability [11]. The systematic application of LCA has allowed companies to develop more effective strategies for reducing their environmental footprints, especially in markets with stringent regulations, such as Europe [2].
The importance of CE and LCA for battery sustainability has been underscored by the introduction of new regulations. The recent European battery regulation, enacted in July 2023, has set a new global benchmark by imposing stricter standards for battery production, use, and disposal [12]. This legislation aims to ensure that batteries used in the European market are produced sustainably and with lower environmental impacts, in alignment with CE principles. Companies aiming to operate in the European market must rapidly adapt to these requirements, which include mandatory recycling and minimizing environmental impacts from raw material extraction to the product’s end of life [13].
The compliance deadlines with these regulations are critical for companies to maintain their competitiveness in the highly regulated European market. A gradual adaptation to these requirements not only ensures their market presence but also prepares them for meeting future regulatory demands in other markets [14]. Moreover, the European Union often sets global regulatory trends, making adherence to these standards crucial for companies aiming to maintain an international presence and solidify their leadership in innovation and sustainability within the automotive sector [10].

One of the regulation’s most innovative provisions is the requirement for batteries to contain a minimum number of recycled materials. This mandate applies to critical metals such as lithium, cobalt, and nickel, promoting the use of recycled materials and reducing reliance on the mining of new resources. This requirement is expected to drive demand for advanced recycling technologies and boost the secondary materials economy in Europe [12].
  • Collection and Recycling Targets
The regulation establishes ambitious targets for the collection and recycling of used batteries. EU member states are required to ensure that an increasing percentage of batteries are collected and recycled, with progressively higher targets extending through 2030. Moreover, the regulation delineates minimum recycling rates for various materials contained within batteries, guaranteeing that a significant proportion of valuable materials are recovered and reintegrated into the economy [12].
  • Innovation and Sustainable Design
The regulation fosters innovation in battery design, promoting the development of batteries that are more easily repaired, upgraded, and recycled. This may encompass modular battery configurations wherein individual components can be replaced or upgraded without the necessity to discard the entire battery. Furthermore, the regulation advocates for the adoption of production technologies that aim to minimize environmental impacts, including reducing energy and water consumption during the production phases [12].
  • Social and Environmental Impact of Mining
The regulation explicitly addresses the social and environmental concerns associated with the mining of raw materials for batteries, such as lithium and cobalt. It mandates that companies operating within the supply chain demonstrate compliance with environmental and human rights standards. These provisions are designed to mitigate the negative impacts of mining and to promote more sustainable and ethical practices in the extraction of raw materials [12].
  • Compliance and Enforcement
To ensure the effective implementation of the regulation, the EU has established rigorous enforcement mechanisms. Companies failing to meet the requirements may face significant penalties, including fines and market restrictions. The EU will also provide technical and financial support to member states to assist in transitioning to these new standards [12].
  • General Implementation of the Regulation
The regulations came into force immediately after their official publication in July 2023, but some requirements have specific deadlines for full implementation. Table 2 shows the main deadlines for implementing EU regulations, highlighting the stages and requirements set for the coming years. The adoption of these measures allows the industry and countries sufficient time to adapt to the new guidelines. Each milestone represents an advance in the quest for greater sustainability, encouraging practices such as traceability, increased recycled content, collection and recycling targets, sustainable design, and extended producer responsibility.
These timelines reflect a phased approach to implementing the regulation, allowing both the industry and countries sufficient time to adapt to the new requirements. This approach facilitates continuous progress towards sustainability and the development of a circular economy.

DateAction
2024Traceability System and Digital Passport: Companies are required to implement a digital passport system for batteries, which must be fully operational by the end of 2024. This system will encompass detailed information regarding the origins of raw materials, battery composition, production history, and performance data.
2027Recycled Content: Starting in 2027, batteries sold within the European Union must contain a minimum percentage of recycled materials. This percentage, determined by various critical materials such as lithium, cobalt, and nickel, will undergo periodic reviews and may increase over time.
2030Recycled Content: By 2030, the minimum recycled content requirements will be elevated, reflecting the growing capacity of the industry to recycle and reuse materials efficiently.
2025Collection and Recycling Targets: By 2030, the recycled content requirements will be heightened to reflect the industry’s growing capacity to recycle and reuse materials efficiently.
2030Collection and Recycling Targets: More ambitious collection and recycling targets are to be met, necessitating a higher percentage of used batteries to be collected, and minimum recycling rates for critical materials such as cobalt, lithium, and nickel must be achieved.
2025Sustainable Design and Innovation: Sustainable design guidelines must be fully implemented, including requirements for easier battery disassembly and recycling. Companies are required to modify their design and production processes to adhere to these new standards.
2025Extended Producer Responsibility: By 2025, extended producer responsibility must be fully realized. From this year forward, manufacturers will bear full responsibility for the entire life cycle of their batteries, encompassing collection and recycling at end of life.
2025Sustainable Mining and Human Rights: By 2025, companies must demonstrate adherence to sustainability and human rights standards in their raw material mining practices. This involves implementing responsible practices within supply chains to ensure minimal social and environmental impacts.
2030Regulation Reviews and Updates: The regulation mandates periodic reviews, with a significant review scheduled for 2030. These reviews will assess progress and adjust goals and requirements as necessary to ensure the achievement of sustainability objectives.
