FiveVB is a consortium founded by the European Green Vehicle Initiative (EGVI) within Horizon 2020 program. The JRC plays an active role in the characterization of the newly developed 5 V battery technology. The batteries, manufactured by the consortium are characterized in the experimental facility of Battery Testing for Safe Electrification of Transport (BESTEST) in Petten by using cycling and post mortem analysis.

The vision of FiveVB project is to push European’s Lithium battery industry and academia to take over a leading role in the development and manufacturing of Lithium Ion cells and materials to provide cost and performance competitive Lithium Ion cells and batteries to European and Non-European Automotive Industry.

  • The first objective is to achieve a higher energy density cell by using innovative actives materials to develop a high voltage cell as well as an assessment of the aging phenomena evaluated by testing and modelling.
  • The second objective is to develop a methodology with the project team that demonstrates how it will be possible in the future to assess and to evaluate advancements in materials that will speed up the development of even better cells after the project is finished.

FiveVB’s scope will focus on the following parameters, critical to automotive requirements and finally consumer’s acceptance.

A short explanation on how FiveVB is addressing these parameters is given as follows:

Energy Density

This proposal is suggesting a new combination of active materials in the cell to achieve the energy density targets outlined in the call. At the anode level, a high specific capacity silicon alloy will be employed in combination with a high-voltage spinel on the cathode side. A new electrolyte system that enables high voltage operation will be integrated in the new proposed concept.


Two different generations of material compositions (G1C & G2C) will be realized on lab scale cell level. The cost issue will be one of the trigger when deciding about the composition of the industrial scale cell. First priority is set on the G2C composition, where especially the battery system costs are optimized, due to the higher cell voltage.


Ageing tests are performed from an early stage in the project. When walking through the generations, the project team is able to increase durability by feeding-back early the results from pre- and post-mortem cell testing. Cell active and passive materials therefore are optimized throughout the generations.

Safety Aspects

This aspect is addressed for the finally produced cell. Tests are carried out to outline clearly the cell behaviour under abuse conditions and the major changes to technologies from today’s state-of-the-art are documented in accordance to relevant standards (e.g. EUCAR hazard level ≤ 4).


The project plan includes a comparative life cycle assessment (LCA). This LCA compares the environmental impacts of the new battery development with existing lithium batteries. Scale-up for manufacturing with an industry-based consortium, all the materials used in the project are coming from industrial partners and the multidisciplinary approach (also multi-industrial) should allow for optimal preparation to meet the final FiveVB objective: An automotive scale industrial PHEV1 cell produced in Europe using materials and technologies provided by European companies.
