Summary
The FiveVB project will develop a new cell technology based on innovative materials such as high capacity anodes,
high voltage cathodes and stable, safe and environmentally friendly electrolytes. Since main European industry
partners representing the value chain from materials supplier to car manufacturer are involved, this program will
support and enable the development of a strong and competitive European battery industry. The multidisciplinary
project team will also assure not only early technology integration between materials, cells, batteries and application
requirements, but also a subsequent industrialization of the developed technology.With an integrated trans-disciplinary
cell development approach we will also realize an early feedback loop from battery and vehicle level to material
suppliers and a feed-forward of relevant information to industrial scale cell production. Through an iterative and
holistic approach two generations of cell chemistries (anode, cathode, binder and electrolyte) will be evaluated and
optimized to improve electrochemical performance of active materials and related new cell technology in terms of
energy density, lifetime, safety and costs. Furthermore, we will address early development and validation of test
procedures for the reduction of development time from material to cell by e.g. accelerated test procedures. Among
other objectives, in particular the lifetime and aging aspects will be addressed in depth in FiveVB, but also input for
future European and International standardization will be provided.Thus, one major result of FiveVB is a hard case
prismatic cell in PHEV1 format, developed according to automotive requirements and produced on a representative
prototype facility.
Work performed
In the first reporting period of the Project (M1-M18; 1st May 2015 - 31st October 2016) the consortium was focusing on the development of the respective materials for the FiveVB cell. Initially the cell requirements were elaborated. In addition to that the test protocols tailored to the novel cell technology have been defined and an economical assessment has been performed.
The development of the battery cell materials (anode, cathode and electrolyte) started with a pre-defined baseline (‘Generation 0 materials’) and was later on further elaborated in subsequent development steps (‘Generation 1 materials’ -> ‘Generation 2 materials’). Generation 0 and Generation 1 materials were assembled and tested on pouch cell level. Generation 2 pouch cell development is currently under progress. The Generation 1 cells featured compared to Generation 0 improved energy density, rate capability and low temperature behaviour; the cycling behaviour for Generation 1 was worse compared to Generation 0 cells. In terms of dissemination a homepage for the FiveVB project was set online. Moreover, a first brochure has been elaborated for dissemination to selected stakeholders. Concerning the Consortia within GV1 a common discussion platform with the consortia eCaiman and SPiCY has been established. For a common appearance a first poster draft describing the three consortia has been brought into discussion.
Final results
The work within the FiveVB-consortium is carried out in a very interactive way. From material researcher to the OEM all consortium members are coming together on a round table, share their experiences and results as well as the issues that they are facing during their development work. By means of such a development approach, developers at every stage of the value chain obtain feedback on their work in a very fast and efficient way, and can adapt their efforts towards the need of other partners. With the help of the FiveVB workflow established in the project a competition advantage compared to other regions in the world (regarding battery cell production in particular Asia) is expected.
From technical point of view the FiveVB technology will lead to higher energy densities at lower cost. By focusing on the topic of E-mobility, this will yield a higher range at lower cost for Electric car drivers. As a consequence of that, the market acceptance of Electric Vehicles will strongly increase. However, the development of industrial scale production techniques for the novel cell materials and cells will be crucial for establishing battery cell production in Europe for meeting the Electric vehicle market demand in terms of cost, efficiency and quality.
