Is Repurposing Ev Batteries For Grid Energy Storage A Sustainable Plan?
Lithium-ion batteries have become an important part of the energy supply chain for transportation (in electric vehicles) and renewable energy storage systems. Recycling is considered the most efficient way to recover materials from the spent LIB stream and circulate the material through critical supply chains. However, very few review articles have been published in the area of recycling and circular economy research; Most of these mainly focus on recycling methods or challenges and opportunities in the circular economy for spent LIBs. This article examined 93 articles (66 original research articles and 27 review articles) identified in the Science Original Collection database. Research has shown that publications in this area have grown exponentially, many focusing on topics related to recycling and recovery; Policy and regulatory issues have received less attention than recycling. Most of the studies were post-experimental evaluations and designs (according to the classification made). Pretreatment processes, which are an important part of hydrometallurgy and direct physical recycling (DPR), are discussed extensively. DPR is a promising recycling technique that needs more attention. Some of the issues that require further consideration include techno-economic evaluation of recycling processes, safe reverse logistics, a global EV assessment that reveals material recovery potential and life cycle assessment of experimental processes (both in hydrometallurgical and pyrometallurgical processes). Additionally, implementation of circular business models and involvement of relevant stakeholders, clear and specific policy guidelines, enhanced producer responsibility practices, and ingredient tracking and identification deserve greater focus. This study presents several future research directions that may be useful for academics and policymakers to take necessary steps to achieve a circular economy, such as product design, integrated recycling strategies, intra-industry stakeholder collaboration, business model development, techno-economic analysis, and others. . LIB Value Chain.
The circular economy (CE) has gained significant attention among policymakers and business stakeholders by addressing issues of resource efficiency and material circularity [1, 2]. The main principles of CE are: (1) elimination of waste and pollution (focusing mainly on the end stage of a product’s life), (2) long-term use of products and materials (representing the middle of the product’s life) any product in circulation. and buried materials) and (3) reproducing natural ecosystems (the important focus here is on environmental sustainability and the implementation of current consumption and production patterns, thus emphasizing the beginning of the life of any product. – material extraction) for the technological cycle and organic for the biological cycle -based materials, non-toxic use of materials and renewable energy) [3, 4). It is an economic tool that pushes the current trend of material use to be slow, narrow and closed-loop with a greater focus on supporting social and environmental goals . Decarbonising the economy with resource mobility has created significant momentum, particularly in the transport and mobility sector, which is a significant contributor to global CO2.
Emissions Electric vehicles (EV) are one of the biggest innovations that contribute to positive environmental performance, without ignoring the source of electricity generation (i.e. the negative impact of coal-fired power generation on the ecosystem). Production of electric vehicles requires the production of a large battery pack. For example, the resource stock of a lithium-ion battery pack is low, given the current technology used in the Tesla EV and others that have a variety of critical cathode materials such as CO, Ni and Li, and anode materials such as Al, Cu. and graphite. Due to their high energy and energy density, lithium-ion batteries (LIBs) are widely used in electric vehicle battery storage systems  as well as in renewable energy supply systems such as solar PV . Furthermore, the application of LIBs in critical components and small electronic equipment (e.g., mobile phones, handheld power equipment, and others) is common . Batteries are generally classified according to their chemistry into lithium-ion batteries (LIBs), lead-acid (PbA) batteries, nickel-metal hydride (NiMH) batteries, and nickel-cadmium (NiCd) batteries . Excluding two- and three-wheelers, the current global stock of electric vehicles reached 7 million as of 2019 and this number is expected to reach 140 million in 2030, thus 7% of the total vehicle fleet . As electric batteries become more widespread, the demand for LIB production will continue to increase . From a product life cycle perspective, LIB is one of the most material-intensive product inventories requiring attention at any stage of their life cycle. End-of-life (EoL) treatment from various waste streams (these are resources in CE) poses unprecedented challenges across all sustainability indicators and pillars. As the end of the pipe solution, one of the ways to circulate the recycling materials; However, heterogeneity in product design and diverse battery chemistries have created significant obstacles along the way. On the other hand, no specific guidelines have been developed regarding the remaining life of LIBs to be used for other purposes and the technical reliability of their use in second-hand applications. Overall, these phenomena pose serious environmental challenges on both the supply and demand sides. As previously mentioned, batteries contain a variety of rare earth elements and metals, which can fill current mineral deficiencies but can contaminate the material if not properly recycled. For example, 55% and 24% were mined from Australia and Chile in 2019, respectively, and Co, a key component of LIB, can only be found in conflict zones such as the Democratic Republic of Congo, where 70% is found. Origin of Ko was published in the same year . Unless appropriate disposal options such as recycling, reuse and remanufacturing are collected and selected in an optimized manner, the goal and progress towards net zero emissions and climate change mitigation from the transport sector will be critically undermined. Traditional linear economics (take-make-dispose) cannot be implemented because some high-value material cycles must be closed-loop to address risks in the global supply chain. On the other hand, CE creates opportunities for product manufacturers and businesses to maximize resource utilization and reduce waste and pollution. Application of circular business models , collaboration of all stakeholders , and data-driven decision support systems  are necessary for proper planning that will comply with CE principles for LIBs. The options mentioned above also illustrate basic CE strategies that integrate the LIB value chain and supply chain lifecycle holistically. Figure 1 shows the LIB value chain.
What Will It Take To Recycle Millions Of Worn Out Ev Batteries?
Recycling techniques for LIBs are still under development, and there is currently no technology that will allow recovery of all components of a used battery (each technology has specific advantages and disadvantages). Moreover, current technological innovation has a lot of losses and at the same time, battery chemistry is constantly improving. Therefore, recycling requires continuous advances in material use, battery system design, and manufacturing processes. This article focuses on LIB recycling and the circular economy and examines original research articles published in peer-reviewed journals to explore interdisciplinary connections between different research dimensions. The Web of Science (WoS) Core Collection database was used for this study. First, searching the keywords “recycling” and “circular economy” with the AND operator as subject reached 3998 articles. Then, in the refined keyword search window, the keywords “lithium-ion battery” or “Li-ion battery” were used, yielding 123 articles including these.
