A comprehensive review and analysis of technology performance characteristics of lithium-ion battery cell manufacturing: Introducing a Call-for-Innovation-Heatmap

The Lithium-Ion Battery is attributed an enabling role for achieving climate policy goals by accelerating the shift of the mobility sector to renewable energy usage and improving renewable energy integration into the energy infrastructure through stationary storage. Thus, challenges related to further optimization of battery technology and its production that need to be tackled to achieve the set goals are manifold. Effective research funding planning is needed to efficiently use resources for advancing cell technologies and its production. However, despite being essential for identifying and prioritizing innovation needs based on technological performance, we perceive that an overview on how current issues in battery cell production hold for impact on a holistic operation site perspective is lacking. Thus, we aim at developing comprehensive process overview specifications for state-of-the-art lithium-ion battery cell production by applying a systematic, methodical approach as well as to derive critical problems and opportunities for targeted innovations application. We contribute to scientific literature by linking process streams and operational innovations in battery cell manufacturing to production management literature. Our findings furthermore have implications for both public research and industrial managers providing guidance on prioritizing development projects aiming at process management efficiency in battery cell manufacturing.
