The only way Europe might become competitive against Asian countries in the battery production is through the development of new chemistry/technologies based on innovative materials and processes in this manufacturing value chain, allowing for:
Altogether, these improvements will allow higher energy efficiency and substantial production cost reductions thus ensuring a real competitiveness based on new technological IP rather than only mass production optimization.
In the GREENLION project, we address the above issues by the industrial development of eco-designed processes at the electrode, cell and battery module level. At the electrode processing stage (that will be otherwise independent of the active materials chemistry), developing and making use of:
At the cell assembly level, further improvements to the existing procedures as well as changes at some steps of the assembly process will be developed to increase energy efficiency and shorten times (and hence lower costs) during the manufacturing process, by implementing:
Finally, developing a modular battery allows an easier handling of cells within a complete battery pack. At this battery module level, GREENLION project will design an autonomous unit including its own electrical and thermal management as a simple and reliable building block that will allow the manufacturing and maintenance of the whole battery packs easier and more inexpensively, with the lowest possible environmental impact. This will be achieved by:
These developments will be scaled-up and realized in pilot lines during the project, following a continuous environmental assessment of materials and processes. A validation of the finally assembled battery module will be carried out leaded by the automotive end-user who will also provide the targets and specifications for EV application.
