“…In addition, highest product safety is absolutely essential; hence, automated in‐line and on‐line data acquisition including evaluation (preferable in real time), as well as automated defect recognition (ADR) must be realized.

The Role of Pilot Lines in Bridging the Gap Between Fundamental Research and Industrial Production for Lithium‐Ion Battery Cells Relevant to Sustainable Electromobility: A Review

Despite intensive research activities on lithium‐ion technology, particularly in the past five decades, the technological background for automotive lithium‐ion battery mass production in Europe is rather young and not yet ready to meet requirements of automobile manufacturers. In light of the strong increase in electromobility, bridging this gap between fundamental research and industrial production is mandatory to keep the value chain of automobile manufacture in European countries. Challenges in know‐how transfer from lab scale to industry scale arise from different product configurations and objectives. Lab scale focuses primarily on material development and screening, utilizes small‐sized half‐cell or single‐layered designs with one‐side‐coated electrodes, and applies manually operated, discontinuous equipment, whereas industry focuses on optimized trade‐offs between throughput, quality, and costs. Market‐relevant cells contain usually double‐side‐coated electrodes with comparatively higher areal capacities, assembled into multilayered configurations. Mass production is conducted through automated, continuous processes including roll‐to‐roll manufacturing and consecutive pick‐and‐place operations. Inevitably, standard laboratory conditions do not allow for prediction of either optimized mass‐production process parameters nor physicochemical characteristics of final products. Hence, this Review aims to identify challenges in transferring lab‐scale results to industry with special focus on pilot lines as intermediate step between the different technological levels.

The timely arrival of novel materials plays a key role in bringing advances to society, as the pace at which major technological breakthroughs take place is usually dictated by the discovery rate at which novel materials are identified within chemical space. High‐throughput experimentation and computation strategy, now widely considered as a watershed in accelerating the discovery and optimization of novel materials in virtually every field, enables simultaneous screening, synthesis and characterization of large arrays of different material classes toward identification of the lead candidates for given system and targeted application. However, the ability to acquire data, through the continued advancement of automation platforms and workflows especially in the field of battery research and development, often outpaces the ability to optimally leverage obtained data for improved decision‐making. Closing this gap inevitably calls for adapted algorithms, development of reliable predictive models and enhanced integration with machine learning, deep learning, and artificial intelligence. This Review aims to highlight state‐of‐the‐art achievements along with an assessment of current and future challenges as well as resulting perspectives toward accelerated development of advanced battery electrolytes and their interfaces.

The replacement of conventional lithium‐ion batteries with solid‐state batteries is currently under investigation by many players both from academia and industry. Sulfide‐based electrolytes are among the materials that are regarded as most promising, especially for application in the transport sector. The performance of anode, cathode, and solid electrolyte materials of this type of solid electrolyte is typically evaluated using manually assembled cells such as Swagelok cells, EL‐CELLs, and in‐house built pressure devices. Coin cells, however, are often disregarded. Though coin cells cannot accurately predict how a material will perform in an end‐use application battery cell format, they are easy to assemble and can provide reproducible data compared to the other cell types, which make them an interesting option for testing the materials under conditions more relevant for their envisioned application. The coin cell preparation method presented in this work has been evaluated interlaboratory for reproducibility and, in addition, can be modified depending on the optimization parameters of the solid electrolyte, cathode material, bilayer comprised on cathode and solid electrolyte, lithium metal anode, and cell in general. Besides, an interlab round‐robin test (RRT) is carried out between four laboratories, measuring defined electrochemical tests of sulfide solid‐state batteries in coin cell configuration. This RRT for the preparation of coin cell solid‐state batteries with sulfide solid electrolyte, lithium nickel manganese cobalt oxides cathode, and lithium metal anode is intended for academic researchers and provides guidelines of research in this field.
