“…Based on previous publications, Drachenfels et al (2021) present variations in scrap rates according to production scales, e.g. 5 to 20% for small and 5 to 10% for large factories [2]. Nelson et al (2019) present process-specific scrap rates, varying from 1 to 8% according to the process characteristics [8].…”

The shift in the mobility sector towards electric vehicles is responsible for a growth in the market demand for lithium-ion batteries. To follow this trend, the current 200 GWh global production capacity of lithium-ion batteries will present an annual increase of up to 300 GWh in the next years. Characterized by an energy-intensive process chain and high material costs, battery production is sensitive to production scrap rate. Current works on energy and cost assessment in battery production consider scrap rates based on static values derived from historical production data. Thus, there is a lack of works that dynamically analyse the influence of different scrap rates on the process chain, e.g. considering machine states and utilisation capacity. To tackle this challenge and contribute to more sustainable and competitive battery production, this work presents a simulation-based methodology to assess the indirect and direct energy demand and costs associated with production scrap.

“…Fontos követelmények, hogy a kötéseknek alacsony elektromos ellenállással kell rendelkezniük és a lehető legkisebb hőbevitellel kell létrehozni megfelelő szilárdság melletta cellák hőérzékenysége miatt. Természetesen a nagyvolumenű gyártás miatt a gazdasági szempontokat is figyelni kell [1,5,6].…”

ÖsszefoglalásA hegesztés az egyik leghatékonyabb és leggazdaságosabb módszer a fémek összekapcsolására. Az ellenállás hegesztés az iparban az egyik leggyakrabban alkalmazott hegesztési technológiáik közé tartozik. Előnye, hogy a kötés létrehozásakor az összehegesztendő lemezek vastagsága minimálisan változik. Az elektronikában is nagy szerepe van ennek a kötéstechnológiának. Az egyre nagyobb mértékű elektromobilitás egyre több és nagyobb méretű akkumulátorokat igényel, melyeket nagyszámú egymással összekapcsolt egyedi akkumulátorcellákból építenek Az akkumulátor cellák összekapcsolásával elektromos és mechanikai kapcsolatot létesítünk, melyet különböző technológiákkal valósíthatunk meg. Cikkünk jelen kötéstechnológiák témakörével foglalkozik. Célunk bemutatni a technológiák működését és az ellenállás hegesztés sajátosságait.

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

2021

View full text Add to dashboard Cite

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.
