In response to these environmental concerns, numerous countries encourage the adoption of electric vehicles (EVs) as a more environmentally friendly option than traditional gasoline-powered vehicles. Advances in battery technology have made batteries an alternative solution for energy storage in stationary applications and for electric mobility. Reduced lithium-ion batteries (LIBs) production costs due to economies of scale, electrode material and cell design developments, and manufacturing process improvements have driven this success. This trend is expected to increase the number of LIBs on the market that may be discarded in the environment at the end of their useful life if more sustainable alternatives are not technologically mature. This coming environmental concern can be mitigated by collecting wasted EV batteries, reconfiguring them, and reusing them for applications with less stringent weight, performance, and size requirements. This method would extend battery life and reduce environmental effects. The present work investigates the main regulatory structures of the second-life battery industry that require rules, technical standards, and laws. To achieve this objective, a systematic review was carried out following a strict protocol that includes identifying relevant studies, extracting data and information, evaluating, and summarizing information. This paper explains the primary rules and technical standards governing the second-life battery business. The findings highlight the need for universities, research institutions, and government agencies to evaluate the second-life battery industry objectively. This would enable the creation of new technological regulations and laws for this burgeoning industry.}, language = {en} } @article{HussenetherRufinoJuniorSelaibePiresetal.2026, author = {Hußenether, Thomas and Rufino J{\´u}nior, Carlos Ant{\^o}nio and Selaibe Pires, Tom{\´a}s and Mishra, Tarani and Nahar, Jinesh and Vaghani, Akash and Polzer, Richard and Diel, Sergej and Schweiger, Hans-Georg}, title = {Analysis of the Measurement Uncertainties in the Characterization Tests of Lithium-Ion Cells}, volume = {19}, pages = {825}, journal = {Energies}, number = {3}, publisher = {MDPI}, address = {Basel}, issn = {1996-1073}, doi = {https://doi.org/10.3390/en19030825}, year = {2026}, abstract = {The transition to renewable energy systems and electric mobility depends on the effectiveness, reliability, and durability of lithium-ion battery technology. Accurate modeling and control of battery systems are essential to ensure safety, efficiency, and cost-effectiveness in electric vehicles and grid storage. In engineering and materials science, battery models depend on physical parameters such as capacity, energy, state of charge (SOC), internal resistance, power, and self-discharge rate. These parameters are affected by measurement uncertainty. Despite the widespread use of lithium-ion cells, few studies quantify how measurement uncertainty propagates to derived battery parameters and affects predictive modeling. This study quantifies how uncertainty in voltage, current, and temperature measurements reduces the accuracy of derived parameters used for simulation and control. This work presents a comprehensive uncertainty analysis of 18650 format lithium-ion cells with nickel cobalt aluminum oxide (NCA), nickel manganese cobalt oxide (NMC), and lithium iron phosphate (LFP) cathodes. It applies the law of error propagation to quantify uncertainty in key battery parameters. The main result shows that small variations in voltage, current, and temperature measurements can produce measurable deviations in internal resistance and SOC. These findings challenge the common assumption that such uncertainties are negligible in practice. The results also highlight a risk for battery management systems that rely on these parameters for control and diagnostics. The results show that propagated uncertainty depends on chemistry because of differences in voltage profiles, kinetic limitations, and temperature sensitivity. This observation informs cell selection and testing for specific applications. Improved quantification and control of measurement uncertainty can improve model calibration and reduce lifetime and cost risks in battery systems. These results support more robust diagnostic strategies and more defensible warranty thresholds. This study shows that battery testing and modeling should report and propagate measurement uncertainty explicitly. This is important for data-driven and physics-informed models used in industry and research.}, language = {en} } @article{VenancioPinzonCAguiardosSantosetal.2025, author = {Ven{\^a}ncio, Raissa and Pinz{\´o}n C., Manuel J. and Aguiar dos Santos, Jo{\~a}o Pedro and Galantini, Isabela and Cruz, Hugo and Rufino J{\´u}nior, Carlos Ant{\^o}nio and Doubek, Gustavo and Branco, Lu{\´i}s and Franco, D{\´e}bora V. and Da Silva, Leonardo M. and Gon{\c{c}}alves, Josu{\´e} and Zanin, Hudson}, title = {Tailoring electrolyte solvation for improved Na-based supercapacitor efficiency: an operando characterization approach}, volume = {14}, journal = {Journal of Materials Chemistry A}, number = {10}, publisher = {RSC}, address = {Cambridge}, issn = {2050-7488}, doi = {https://doi.org/10.1039/D5TA07938A}, pages = {5786 -- 5805}, year = {2025}, language = {en} } @article{RufinoJuniorRivaSanseverinoGalloetal.2022, author = {Rufino J{\´u}nior, Carlos Ant{\^o}nio and Riva Sanseverino, Eleonora and Gallo, Pierluigi and Koch, Daniel and Schweiger, Hans-Georg and Zanin, Hudson}, title = {Blockchain review for battery supply chain monitoring and battery trading}, volume = {2022}, pages = {112078}, journal = {Renewable and Sustainable Energy Reviews}, number = {157}, publisher = {Elsevier}, address = {Amsterdam}, issn = {1879-0690}, doi = {https://doi.org/10.1016/j.rser.2022.112078}, year = {2022}, language = {en} } @article{RufinoJuniorRivaSanseverinoGalloetal.2024, author = {Rufino J{\´u}nior, Carlos Ant{\^o}nio and Riva Sanseverino, Eleonora and Gallo, Pierluigi and Amaral, Murilo Machado and Koch, Daniel and Kotak, Yash and Diel, Sergej and Walter, Gero and Schweiger, Hans-Georg and Zanin, Hudson}, title = {Unraveling the Degradation Mechanisms of Lithium-Ion Batteries}, volume = {17}, pages = {3372}, journal = {Energies}, number = {14}, publisher = {MDPI}, address = {Basel}, issn = {1996-1073}, doi = {https://doi.org/10.3390/en17143372}, year = {2024}, abstract = {Lithium-Ion Batteries (LIBs) usually present several degradation processes, which include their complex Solid-Electrolyte Interphase (SEI) formation process, which can result in mechanical, thermal, and chemical failures. The SEI layer is a protective layer that forms on the anode surface. The SEI layer allows the movement of lithium ions while blocking electrons, which is necessary to prevent short circuits in the battery and ensure safe operation. However, the SEI formation mechanisms reduce battery capacity and power as they consume electrolyte species, resulting in irreversible material loss. Furthermore, it is important to understand the degradation reactions of the LIBs used in Electric Vehicles (EVs), aiming to establish the battery lifespan, predict and minimise material losses, and establish an adequate time for replacement. Moreover, LIBs applied in EVs suffer from two main categories of degradation, which are, specifically, calendar degradation and cycling degradation. There are several studies about battery degradation available in the literature, including different degradation phenomena, but the degradation mechanisms of large-format LIBs have rarely been investigated. Therefore, this review aims to present a systematic review of the existing literature about LIB degradation, providing insight into the complex parameters that affect battery degradation mechanisms. Furthermore, this review has investigated the influence of time, C-rate, depth of discharge, working voltage window, thermal and mechanical stresses, and side reactions in the degradation of LIBs.}, language = {en} } @article{SantosNetoKanieskietal.2025, author = {Santos, Cassiano and Neto, Milad Kalume and Kanieski, Jo{\~a}o Marcos and Rufino J{\´u}nior, Carlos Ant{\^o}nio and Schweiger, Hans-Georg and Zanin, Hudson}, title = {A multidimensional assessment of electrification in automotive powertrains: Technical, operational, and strategic perspectives}, volume = {2025}, pages = {107377}, journal = {Results in Engineering}, number = {28}, publisher = {Elsevier}, address = {Amsterdam}, issn = {2590-1230}, doi = {https://doi.org/10.1016/j.rineng.2025.107377}, year = {2025}, abstract = {Global transportation is undergoing a profound transformation, driven by the convergence of decarbonization targets and advances in electrification technologies. Electrification, ranging from mild Hybrid Electric Vehicles (mHEVs) to Battery Electric Vehicles (BEVs), represents the main technological path in the transition from internal combustion engines. This transition is inherently multidimensional, simultaneously reshaping vehicle design, manufacturing systems, supply chains, customer value, and environmental outcomes in interconnected ways. Each architecture, including mHEV, Hybrid Electric Vehicle (HEV), Plug-in Hybrid Electric Vehicle (PHEV), and BEV, presents different tradeoffs in these dimensions, requiring a structured framework for systematic comparison. To address this gap, this work details an integrated framework that systematically compares electrification pathways across five interrelated dimensions: vehicle concepts, research and development, manufacturing and logistics, customer experience, and environmental footprint.
