“…For many applications that rely on mobile energy storage, the lithium-ion batteries have emerged as the best solution in recent years. Production of the cells is divided into three main segments: electrode production, cell assembly, and activation or formation [5]. In electrode production -on which the explanations in this contribution focus -the production for anode and cathode follows the same process steps.…”

On the path towards a sustainable society, the availability of energy storage systems is an essential step – leading to increased demand for batteries. To achieve a sustainable society, it is necessary to manufacture batteries also in a sustainable way. One approach lies in virtual experiments. They aim at identifying parameters, recipes, and technologies in the digital world, before applying them to the physical production system. Thus, manufacturing is optimized in regard to sustainability indicators such as material consumption, emission, and waste – but also in regard to costs, quality, and yield. The faster ramp-up is especially important in the production of battery cells, due to the highly complex processes and critical materials. In this paper, we introduce a concept for virtual experiments platform in battery cell production. It includes collection of data, data aggregation, a simulation environment, as well as an optimizer. Also, it is integrated into existing production and IT systems. The virtual experiments platform functions as a service of a digital twin. Validation is conducted by realizing the virtual experiments platform on the electrode production of lithium-ion batteries.

Owing to constantly increasing energy density and power density, thermal runaway is becoming the most dangerous event in lithium‐ion batteries, while gas sensing can provide the earliest and clearest signals for forewarning the advent of thermal runaway. However, gas‐sensing signals are not included in current battery management systems (BMSs). Especially for the challenging in‐cell sensing, gas sensing demonstrates significant advantages over out‐of‐cell sensing in the aspect of collecting signals precisely and in a timely manner. The integration of gas sensing with batteries is an important and valuable topic. In this review, the necessity and challenge of in‐cell sensing are expounded, the importance and promise of in‐cell gas sensing are highlighted, optical fiber‐based gas sensing technologies for in‐cell applications are summarized, and the engineering issues of integrating sensors with battery system are discussed. The topic of this article deserves more attention and efforts for the development of cell‐level BMSs and safe batteries in future.

“…This strategy is known as "conventional production" and is widely adopted by influential battery manufacturers. [20,49] Nevertheless, continuous advancements are being pursued to enhance the manufacturing process by implementing state-of-the-art alternatives. Promising avenues include the prospective replacement of conventional intensive and planetary mixers with continuous mixers, [49,50] which holds the potential to improve efficiency and productivity.…”

Cost‐savings in lithium‐ion battery production are crucial for promoting widespread adoption of Battery Electric Vehicles and achieving cost‐parity with internal combustion engines. This study presents a comprehensive analysis of projected production costs for lithium‐ion batteries by 2030, focusing on essential metals. It explores the complex interplay of factors, including economies of scale, R&D innovations, market dynamics, and metal price trends. The findings highlight the significant role of R&D innovations and economies of scale in substantial cost reductions by 2030, with projected ranges of 21‐28% and 25‐37%, respectively. However, potential cost escalations due to elevated metal prices, particularly for nickel‐cobalt‐containing chemistries, are also cautioned. To address these challenges, the study proposes a strategic shift towards robust LFP chemistry to mitigate cost pressures and meet predefined cost targets. Moreover, by analyzing medium or low metal price trends, the study reveals the potential for significant cost savings, with exceptional scenarios demonstrating up to a remarkable 65% reduction in costs. Given the broad range of cost likelihoods, the study underscores the importance of vertical integration and international cooperation in managing the essential metals supply chain securely. The research has profound implications for policymakers and industry decision‐makers, providing valuable insights into the lithium‐ion battery industry.
