Traction battery systems in mobility applications today are built primarily from lithium-ion battery cells. Driven by the expected growth of the electrified vehicle market and the requirements for better performance, numerous next-generation battery technologies are being intensively researched. 
Each of these potential cell chemistries requires a new cell design and thus influencing the integration of the cells into higher levels. Considering future-oriented product development, it is crucial to clarify the advancement of battery technologies as well as the associated opportunities and risks for developing mobility systems.  An initial methodological framework – Cross-Level Impact Analysis (CLIA) Approach – was proposed for systematically modelling dependencies within the battery system and tracing property changes across (sub)systems.
The literature review aims to provide a comprehensive overview of traction battery development, focusing on cell chemistries, battery system design, and the evolution of development processes. You shall examine both current and next-generation battery technologies, including lithium-ion (LIB) and solid-state batteries, and analyze their design and system-level implications. Historical context, such as key milestones in battery and electric vehicle development, will also be considered to establish a data foundation for later retrospective and scenario-based analyses. 

Tasks:

• Survey the status or trends in battery cell chemistries including LIB and emerging technologies
• Research and analyse battery system design trends in both current and next-generation vehicles.
• Investigate historical development milestones for current and emerging cell chemistries, such as:
• Invention and adoption timeline in vehicles of LIB / emerging technologies
• First commercial EVs and system designs using LIB / emerging technologies
• Synthesize technological trends and innovations to highlight advancements and challenges in the field.
• Structure knowledge and insights to support retrospective analyses and scenario studies.

Profile:

• Study of mechanical engineering / materials science / mechatronics / electrical engineering
• Interest in battery system technology, previous knowledge in the field of battery (cells) helpful
• Independent, structured way of working and analytical thinking
