“…Its duplicate cell C01 was more stable, demonstrating the more regularly observed early-life decrease and late-life increase in DCIR. An initial decrease in DCIR has also been reported by Gailani et al [5] but is otherwise seldom reported in literature. The phenomenon could be related to several possible causes, of which one could be variations in the formation process between cell candidates [17].…”

“…All cycled cells also showed swelling at end of testing, especially cells cycled at high charge C-rates. Compared to cell tests done at similar test conditions presented in literature, the cycle life at 1C show higher values in our case for cell types B and C but generally lower values for cell type A [5], [7], [8]. In addition, for cell type C, a time-dependent ageing mechanism was also measured by means of a calendar ageing test at 50 % SOC.…”

During the last decade, the market interest for electrified vehicles has increased considerably alongside global climate initiatives. This has coincided with vast improvements in automotive-grade, lithium-ion battery performance. This has increased the range of battery electric vehicles and plug-in hybrids but lifetime remains a challenge. Ageing during fast charging is especially difficult to understand due to its non-linear dependence on charge rate, state-of-charge and temperature. We present results from fast charging of several energy-optimized, prismatic lithium-ion battery cell generations with an NMC/graphite chemistry through comparison of capacity retention, resistance and dQ/dV analysis. Changes in cell design have increased energy density by almost 50 % over six years of cell development and acceptable cycle life can be expected, even under fast charging, when restricting the usage of the available capacity. Even though this approach reduces the useable energy density of a battery system, this trade-off could still be acceptable for vehicle applications where conventional overnight charging is not possible. The tested cell format has been used for a decade in electrified vehicles. The ongoing development and improvement of this cell format by several cell manufacturers suggests it will continue to be a good choice for future vehicles.

“…High temperatures and state of charge are critical factors contributing to the rapid decline in battery efficiency and capacity, and understanding these processes is key to developing strategies for their effective repurposing and utilization [10][11][12][13]. Accurate diagnostic and prognostic models for secondary energy storage systems are essential to maximize the performance and lifespan of repurposed EV batteries [14][15][16]. These models must account for factors such as calendar aging and cyclic aging, which significantly impact battery degradation.…”

The rapid expansion of the electric vehicle market has significantly increased the demand for lithium-ion batteries, posing challenges for manufacturers and policymakers regarding efficient use and recycling. When these batteries reach the end of their primary lifecycle, their repurposing for secondary applications such as energy storage becomes critical to addressing environmental and resource management issues. This paper focuses on applying second-life batteries in energy storage systems, emphasizing the importance of accounting for calendar and cyclic aging factors to optimize battery performance and longevity. Calendar aging refers to the degradation that occurs over time due to chemical reactions within the battery, even when it is not in use. This type of aging is influenced by temperature, state of charge (SOC), and storage conditions. Cyclic aging, on the other hand, results from repeated charging and discharging cycles, which cause mechanical and chemical changes within the battery, leading to capacity fade and increased internal resistance. The combined effects of these aging processes necessitate the development of high-precision diagnostic and prognostic models to manage the performance and longevity of second-life batteries effectively. In Ukraine, the adoption of electric vehicles is accelerating, leading to an influx of used electric vehicles. This situation necessitates the prompt development of strategies for repurposing these batteries for energy storage applications. The complexities associated with final recycling processes make secondary use an attractive interim solution. By repurposing used EV batteries, Ukraine can mitigate immediate challenges related to battery waste and resource scarcity while supporting the transition to renewable energy sources. This paper highlights the need for an integral degradation index (DI) that combines calendar and cyclic aging factors with stochastic influences to provide a comprehensive measure of battery health. Such an index is essential for optimizing battery management practices, including the scheduling of charging and discharging cycles, to extend the operational life of secondary batteries. The study also presents practical recommendations for implementing these models in various energy storage scenarios, ranging from residential solar energy systems to industrial grid support and electric vehicle charging stations. By adopting optimized battery management strategies, the potential for extending the lifespan of secondary batteries and reducing operational costs is significant. This approach supports sustainable energy practices and aligns with global efforts to promote renewable energy sources and circular economy principles. Keywords: Lithium-Ion Battery, Electric Vehicle, Energy Storage, Battery Degradation, Calendar Ageing, Cyclic Ageing, Integral Degradation Index, Remaining Useful Life, State of Health.

“…For instance, Tesla has claimed to develop a newer variant of the Lithium-ion battery that can back up the EV for around 300 miles in a run [13]. Samsung's Lithium-ion battery with 20 min charging cycle runs EV up to 375 miles [14,15]. Government agencies such as the US Department of Energy have dispatched measures to initiate charging ports and stations near the large EV parking spaces [16].…”

Electric vehicles (EVs) in Malaysia are gaining more attention and interest from the public. However, the electric vehicle’s exposure, awareness, and sales are still low compared to other countries. In this review, the challenges associated with implementing the electric vehicle culture in Malaysia are thoroughly reviewed, including the obstacles that the Malaysian government, policymakers, EV manufacturers, and EV users face in terms of EV cost, travel demand, charging station availability, impact on the power grid, and battery capacity. Then, all the identified challenges have been addressed by considering the user behavior, travel demand, socio-economical culture of Malaysia, current policies taken by the government of Malaysia, and the psychological outlook of Malaysians towards EV adoption. Moreover, potential suggestions have been proposed that the government of Malaysia may adopt during policy planning and when seeking to provide incentives to the users. Finally, a concrete conclusion has been drawn by disseminating the vision about the future of EVs in Malaysia. The proposed review of the technologies, challenges, prospects, and potential solutions associated with EV adoption in Malaysia can provide a base for proper strategic policy and help policymakers frame strategies to achieve the targets. This review could help achieve sustainable EV transport, and the successful implementation of Malaysian National Automotive Plan 2020, with the goal of adopting next-generation green vehicles.
