The transition to renewable energy is essential for sustainable development, in which advanced energy-efficient storage solutions, in particular rechargeable batteries, play a key role. Batteries are becoming increasingly important not only for electric mobility and grid balancing, but also for industrial and residential applications. However, as energy density increases, so do safety risks such as thermal runaway, which can jeopardise user confidence. The aim of this study is to examine the battery technology value chain at a systemic level, with a particular focus on the role of safety testing and technological innovation. The research identifies three main gaps in literature: the lack of value chain level integration, the under-representation of AI-based safety technologies, and the limited comparison of regional (EU, US, Asia) regulatory regimes. By examining the interrelationships between material selection (cathode, anode), cell design, testing protocols and regulatory environment, the study highlights the complex challenges and development directions for battery energy storage. The study reviewed global industry trends and critically assessed forecasts and analyses from international consultancies such as Ernst & Young (EY). These concluded that thorough testing of lithium-ion batteries is key to ensuring long-term reliability, safety and performance by reducing operational risks and increasing product efficiency. Advanced testing infrastructure not only serves quality control and regulatory compliance, but also makes a fundamental contribution to increasing energy efficiency and supporting the green transition. For Europe in particular, it is of paramount importance to expand testing capacities to enable the continent to take a leading role in the safe and sustainable development of batteries.

Standardised battery tests are essential for evaluating the safety, reliability, and performance of modern battery technologies, especially with the rapid emergence of innovations such as solid-state and lithium–sulphur batteries. This review reveals critical shortcomings in current international standards (e.g., IEC, IEEE, SAE), which often do not keep pace with technological developments and are not harmonised across regions, limiting their effectiveness in real-world applications. The paper stresses the need for the continuous review of test protocols through collaboration between researchers, manufacturers, and regulators. A detailed case study of the BYD Dolphin battery demonstrates the practical importance of comprehensive testing in real-world conditions, spanning electrical, thermal, and mechanical ranges. The review concludes that up-to-date, harmonised, and scenario-specific test methods are needed to ensure accurate battery assessment, support global comparability, and enable the safe introduction of next-generation batteries for electric mobility and energy storage. Future work should prioritise operational monitoring, open access data sharing, and the development of sustainability-focused practices such as recycling and reclamation.

In an era where sustainability has become a pivotal concern, the battery industry emerges as a beacon of hope for innovation and economic transformation. Batteries are a cornerstone of sustainable development. They provide an essential energy storage function, facilitating the transition to renewable energy sources and decarbonization. Batteries enable efficient storage and distribution of renewable energy and reduce dependence on fossil fuels. This results in mitigating environmental pollution and contributing to a more sustainable energy landscape. Batteries are, therefore, a fundamental driver of both energy and environmental sustainability. The integration of testing capacities in battery factories and third-party locations is crucial for ensuring product reliability, safety, and performance. In turn, this reinforces market confidence and consumer adoption of the new sustainable applications batteries support. By investing in advanced testing facilities, the industry adheres to stringent quality standards and promotes technological advancements and R&D. This contributes to the economic and sustainable growth of the sector. This approach demonstrates a commitment to continuous innovation, product excellence, and a multitude of sustainability factors, highlighting the essential role of testing in the burgeoning battery industry. In summary, the battery industry is at the intersection of sustainability and economic growth. Our publication shows how the strategic infrastructure development of the innovation-focused battery sector can offer a new perspective on achieving sustainable and economic growth and how it can play a key role in this global transformation.

The rapid spread of electric vehicles offers numerous opportunities to reduce greenhouse gas emissions, but also creates new and complex challenges for the automotive industry, particularly in terms of battery life cycle management. Electric cars are currently powered mostly by lithium-ion batteries, which rely on critical raw materials such as lithium, cobalt, nickel, and manganese. These resources are limited, and their extraction often involves energy-intensive and polluting mining processes that can have a serious impact on soil, water resources, and local communities. As demand for electric vehicles grows worldwide, so does the pressure on the sustainability of raw material supplies. The efficient recycling of batteries plays a key role in solving these problems. Recycling not only reduces the demand for primary raw materials, but also reduces waste and contributes to lowering the environmental footprint of electromobility. The study provides a comprehensive overview of the methods currently used to recycle electric vehicle batteries. The most common technologies include pyrometallurgical processes, which recover metals through high-temperature smelting, hydrometallurgical methods, which use chemical solutions to extract valuable materials, and direct recycling, which aims to reuse individual battery components directly. Each solution has its own advantages and limitations in terms of efficiency, cost, environmental safety, and industrial scalability. The study also pays special attention to new, innovative approaches. Automated dismantling technologies, for example, can make dismantling processes safer and faster, while reducing risks to human health. Finally, the regulatory environment and industry practices also play a key role in ensuring the long-term sustainability of battery recycling and the supply chain. The aim of the study is to contribute to the development of a circular automotive industry and to support the spread of sustainable battery management from both a technological and industrial perspective.

The study examines the observance of safe following distances under real traffic conditions. Maintaining an appropriate following distance plays a key role in accident prevention, as it gives drivers sufficient time to perceive hazards and react appropriately. To record empirical data, a rear radar sensor was installed on the test vehicle, which continuously measured the distance and speed of the vehicle behind. This method allowed for a detailed analysis of how the following distance changes as a function of speed. The collected data was compared with the minimum safety requirements based on reaction time and braking performance described in the literature. The comparison shows the extent to which actual driver behavior deviates from the recommended safety standards. Although modern vehicles are increasingly equipped with driver assistance systems, such as automatic emergency braking, the vast majority of vehicles in Hungary are not yet equipped with such systems. As a result, road safety depends largely on individual driver decisions and compliance with the rules. The results highlight the potential accident risks arising from inadequate following distances, especially in everyday traffic situations where drivers often underestimate the distance required for a safe stop. The measurement result show that most drivers following distance is shorter than the average stopping distance. The research contributes to a deeper understanding of domestic driving habits and provides a basis for the development of road safety campaigns, driver training programs, and possible regulatory measures. Overall, the results emphasize the importance of maintaining a safe following distance as a simple, cost-effective, and efficient means of improving road safety.
