This presentation will provide an overview on state-of-the-art and future battery cell technologiesand well as critical analysis of opportunities and disadvantages of upcoming cell technologies.In addition, concepts for maintaining a high-safety level at high energy densitiesand the presentation of in-house thermal propagation study will be discussed.

Cells chemistries based on Solid-State Electrolytes (SSE) can be characterised by improved safety and a wide temperature stability/working range, and potentially lead to low cost and high energy Electrochemical Energy Storage (EES) systems. In this perspective presentation, Nissan, in partnership with a leading university, will discuss the state-of-the-art in research, and some of the challenges and opportunities toward large scale production for xEV application.

Battery cell faults dominated the news in 2020 triggering recalls and costing billions in replacement costs, fines, lawsuits and collateral brand damage. The timing couldn’t have been worse. Just as OEMs were pledging huge investments to transition away from ICE’s, consumers were being told not to park their car in the garage for fear they’d explode. It’s time for OEMs to get proactive about battery QA. In our talk, we review how a comprehensive, data-analytics approach to qualification, production and after-sales can help OEMs and suppliers maximize battery reliability, safety and lifespan.

Materials and cell chemistry are the fundamental for xEV batteries. FinDream Battery Co Ltd. (former BYD Lithium Battery Co. Ltd.) puts a significant amount of research efforts at materials and cell chemistry level, and consequently has acquired adequate understanding towards their application in xEV batteries. In this talk, we would like to share examples of our research and discoveries, and discuss our understanding on the mechanism behind.

AVL’s series battery benchmarking program provides a database for objective comparison in technical attributes, as well as in engineering methodology, for BEV battery market competitors for clear-system, target definition of high-performing, reliable, and safe batteries. Two-hundred seventy different criteria are evaluated through AVL benchmarking metrics displayed in 8 high-level attributes. The found integrated system performance values are pointed out to support current and future development programs.

For years, the holy grail of cathode chemistry research has been unlocking the path towards high nickel compounds and associated long driving range. Recently, a whole set of new cathode requirements has surfaced and transformed the search for the overall optimal cathode material into a multi-disciplinary quest. Raw material availability, sustainability performance, CO2 footprint and “economical density” (i.e. US$/kWh) have all become crucial design parameters. During this talk, several emerging cathode families (monolithic, high voltage medium nickel, Mn-rich,…) are evaluated on all these different aspects

12V electrical power supply is often essential for vehicle functions that need to be qualified for functional safety, for example, for driver assistance or autonomous driving functions. Such new functions give rise to requirements for the 12V energy storage system, typically comprised of a commodity lead-based battery block and a standardized sensor in the terminal clamp. The talk discusses low-cost commodity solutions for such upcoming applications.

Clarios is continuously working on an optimization of AGM batteries. New requirements for CO2 reduction are impacting the specifications and therefore the design on AGM batteries. Clarios develops a new range of AGM charge acceptance optimized batteries, meeting those new requirements. The presentation will cover the main targets of these engineering activities.

Based on CO2 and pollutant emission legislations in China and Europe as well as added comfort function consumers, requirements on 48V batteries will be elaborated. Major technology trends in terms of cell chemistry, cell formats and interconnection are derived. Moreover, installation locations in the vehicle as well as resulting battery dimension trends and thermal management options will be shown.

A holistic solution satisfying the future battery system and vehicle architecture requirements will be presented.Smart and simplified whilst being safe and secure.   

This presentation will summarise what happened to the European EV market during 2020, implications of COVID-19, market growth, which new vehicles sold best, and what is to be expected for 2021 and onwards. The presentation will also discuss what is expected for battery demand going forward, with its basis on real data from vehicle registrations, both from a world perspective, but also in Europe.

Stian Madshus, VP Battery Materials Europe in Elkem, will argue for the importance of a localised supply-chain of sustainable synthetic graphite anode material in Europe. 

Investor perceptions around the electrification of transport and potential winners throughout the supply chain remain volatile. As technology and regulations evolve, so do expectations around adoption rates and where value will be created. From a listed corporate perspective, the focus remains harnessing growth across the supply chain globally, both organically and through M&A/strategic investments. Strong ESG fund flows provide a strong opportunity for raising capital across both public and private markets. As the market matures, demonstrating a path to sustained returns will become increasingly important.

Battery systems are complex systems with the battery cell as the core technology of the system, but then integrated with multiple subsystems, including mechanical, thermal, and battery management systems (BMS). This presentation will look into the different subsystems that contribute to the overall battery system performance and opportunities for improvement in next-generation battery systems.  Battery system trends in the industry will be evaluated and discussed.

EUROBAT will present its “Battery Innovation Roadmap 2030”, demonstrating the strong innovation potential of all battery technologies in the coming years to cater for the specific requirements of a multitude of applications - automotive, motive power, telecom and stationary.  All battery technologies – lead, lithium, nickel and sodium based - with their specific features and significant development potential, are required to play their role. As an essential technology contributing to decarbonisation across a number of sectors, including transport, energy, logistics, manufacturing and telecommunications, batteries will be crucial in supporting the European Green Deal and achieving  Europe’s 2050 climate-neutrality goals. The Roadmap is particularly relevant given the current European Union policy discussions on the sustainability of batteries, their innovation potential as well as their relevance for job creation and growth.
