Final Report Summary - GREENLION (Advanced manufacturing processes for Low Cost Greener Li-Ion batteries)

Executive Summary:
During the first year, GEN0 prototype cells (10–14Ah) were assembled as baseline for the project, from electrodes prepared with commercially available water-soluble binders and graphite/LiFePO4 (C/LFP) chemistry.
The NMC and SLP 30® electrodes (around 1 m2) prepared in a pre-pilot automated coating line were used to assemble GEN1 small pouch cells (0.5-1.5Ah), following the first large cell design (30Ah target) proposed to fulfill the energy requirements of the end-users for an efficient automotive battery module.
While laser notching trials of electrodes with both PVDF and water-based binders were underway, conventional cutting dies (mechanical notching) and manual stacking process were used for GEN0 and GEN1 cell assembly. Automated stacking-winding would be implemented for the GEN2 cell that was adopted as the most efficient electrical and thermal design for high power performance.
The next step was the accomplishment of large area coating of GEN2 electrodes (Graphite anode and NMC cathode). Drying issues were observed in the coating line for these formulations using CMC as binder, especially for the cathode, which was finally manufactured with PVDF in NMP as solvent. New and improved electrode formulations for NMC cathode and a surface modified graphite anode using water-soluble binders were developed in parallel for a final selection and GEN3 manufacturing. The assembly of GEN2 cells (first batch, 30 cells) with the manufactured rolls of electrodes was completed. Up to 45 cells were delivered for testing as well as first prototype module (Mod1) assembly.
The design of a lighter battery module first prototype suitable for automated assembly and easier disassembly was performed, coupled to the GEN2 power oriented cell design. Different aspects such as minimum mechanical fitting by the assembly process, modular assembly including liquid cooled cold plates, mechanical absorption of cell swelling and venting were considered. Mod1 was the first prototype, manufactured using the developed cell technology (GEN2). Mod1 was built manually but some industrial processes were used such as the tab bending and tab welding stations. A preliminary internal CAN communication was established between the module and the outer BMS. On the other hand, the cooling plate that would operate attached to the module was designed and would be manufactured in a short term.
LCA and recycling activities were fed at this stage of the project with more specific data and this activity was more focused on the expected final designs and processes.
The main activity during the last period of the project was focused on the final product side, i. e.:
Definitive GEN3 cells manufacturing with both electrodes coated from aqueous slurries(over 100 samples)
Six modules assembly and testing
Final data analysis for the LCA
Definitive PUDF: exploitable results and closure workshop as dissemination main event
On the other hand, some activities related to cells parts improvement continued, such as the achievement of a high temperature stable separator, a safer electrolyte with respect to the Hazard Level (HL) tests on cells and the effect of ionic liquids on the electrolyte conductivity and stability. On the other hand, finally, the goal of the simultaneous double side coating on electrode was achieved and some cell prototypes were assembled and tested.

Project Context and Objectives:
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:
the more environmentally friendly production of the battery components;
the substantial shortening of the battery assembly procedure, and
the easier and more effective disassembly and end-of-life recycling.
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:
aqueous slurries rather than toxic organic volatile compounds (25% cost reduction);
non-thermoplastic polymers that allow for high temperature drying, which results in shorter and less expensive assembly procedure (10% efficiency); and
easily disposable non-fluorinated polymers (at expected 10 times less materials cost).
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:
laser cutting instead of mechanical notching of the electrodes (15% cost),
adjusted stack winding of components from aqueous-based electrodes and their drying process before electrolyte filling and sealing, to lower dry room requirements,
environmentally friendly bonding process for more effective and long-life cell sealing, and
adjusted formation step time (ideally for electrodes with reduced formation cycle) in cell manufacturing line (5% time reduction).
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:
lighter battery module designs (including electronics) by implementing air cooled solutions instead of liquid cooling systems (expected 20% less weight),
bonding process of module housing for safe operation but easy disassembling for maintenance and reuse/recycling at their end-of-life, and
automation of module assembly process (3 seconds per cell vs. manual assembly).
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.
Among the main research topics of the GREENLION Project, are to be highlighted the development of ionic liquid-based electrolytes and the realization of electrodes, prepared through innovative, eco-friendly process routes, based on high-voltage cathode and large-capacity anode materials.
Our basic idea was to favorably combine different IL sets in order to obtain ionic liquid mixtures with improved performance. PYR13FSI-PYR13TFSI mixtures were prepared and investigated in terms of NMR spectroscopy, transport properties and density measurements. Remarkable conduction values, e.g., approaching 10-3 Scm-1, were achieved already at -20°C for mole fraction ranging from 0.6 ≤ x ≤ 0.8. This highlights the synergic effect exhibited in ionic liquid mixtures, especially for low temperature applications.
Commercially available NMC cathode and Timcal SLP 30® graphite anode tapes based on the aqueous CMC binders were prepared using a pre-pilot automated coating line. The cycling performance tests evidenced a time-stable capacity of 130 mA h g-1 for more than 40 cycles with coulombic efficiency higher than 99.0 % for the NMC cathodes. The SLP 30® anodes showed very good performance in terms of reversibility of the intercalation process. The specific capacity leveled 375 mA h g-1 after a few cycles. Upon 80 cycles, the SLP 30® electrodes showed still high cycling stability and columbic efficiency above 99.9 %. These results supported for a further development of the aqueous CMC binder-based electrodes.
In addition, alternative water-soluble binders were studied. Impressive electrochemical performance had recently been reported for Si nanopowder and nanowire anodes prepared from aqueous slurries using 15 wt.% alginate as binder. It was apparent from developed tests that the graphite anode with 7.5 wt% alginate outperformed that with 10 wt% PVDF (a common commercial level) over the course of the first 65 charge/discharge cycles. This result suggested that alginate may be a suitable candidate for aqueous manufacturing of anodes.
The most efficient way of manufacturing battery electrodes is to simultaneously coat both sides of the substrate and to use a flotation dryer for removing the solvent. This configuration requires one of the coatings to be applied in the so called kiss coating mode for the slot coating process. Coating trials were carried out on a pilot machine, allowing the adjustment of parameters to achieve an excellent uniformity of the kiss-coated layer, i.e. by suppressing cross lines generated by web flutter in the flotation dryer, and by suppressing longitudinal bands generated by web deformations upstream of the slot die.
During the first year, GEN0 prototype cells (10–14Ah) were assembled as baseline for the project, from electrodes prepared with commercially available water-soluble binders and graphite/LiFePO4 (C/LFP) chemistry.

Potential Impact:
GREENLION will provide advances to a number of scientific and engineering challenges for battery cell and module manufacturing, and their performance thereof. The successful resolution of these will lead to breakthroughs in automotive lithium ion batteries for electric vehicles and thus to the development of a sustainable mobility and quality of life.
Greening our transport system is necessary not only to avoid the influence of oil supply ($147 per barrel peak in 2008) but also to achieve EU and international targets in emissions reductions. In the EU, 19% of total greenhouse gas emissions and 28% of CO2 emissions in 2005 are linked to the transport sector. More than 90% of the total EU transport-related emissions are due to road transport. While total EU emissions declined, transport emissions increased continuously between 1990 and 2005 due to high growth in both passenger (28%) and freight transport (62%).
Current and near-term (i.e. Li-ion) battery technology development is one of the key factors on the Mobility Electrification and the large scale production of these automotive batteries and reducing their costs is, in fact, critical for market entry and acceptance of Electric Vehicles. In order to achieve a break-even cost with internal combustion engines, battery costs must be reduced from the current estimated range of 675 € to 500 € per kilowatt-hour (kWh) at high volume production (order of 100 k units) down to 350 to 275 €/kWh by 2020. R&D to improve power (W/kg) and energy density (Wh/kg) in order to increase driving autonomy, reductions in recharge time and achieving life cycles that approach vehicle life spans is also imperative. Increasing production rate from 10,000 to 100,000 batteries/year reduces cost by ~30-40% [5].
GREENLION addresses further reduction costs driven not only by high volume manufacturing, but also from the components processing conditions. The use of water based binders, an order of magnitude cheaper than conventional fluorinated ones will drive down the cell manufacturing costs, besides being more environmentally friendly and eco-sustainable at the end of life of the cells. Besides the improvement in environmental, health and safety terms (including "working-condition-friendly" considerations), the initial inversion and running costs of the solvent recovery system would be avoided and water is indeed cheaper than NMP. Even though in current production plants the recovered NMP is purified and offered again at 50% of the cost of pure solvent, distilled water is also cheaper (0.20 €/L) than 50% of pure NMP 0.90 €/L (~1.8 €/L pure).
Expected impact in the field of new competitive processes, by means of production automation is also foreseen. Not only will the results of the project efforts enable lower cost and greener lithium battery packs production, but also equipment manufacturing and high added value processes will be developed. These new automated processes will contribute to a substantial cost reduction of lithium battery packs, and will facilitate their introduction to mass production.
Automation and new process development will improve the quality and yield of the production, while at same time reduces labor costs per kWh. This project, with the development of the specific equipments for module assembling, will enable a cycle time of 3 seconds for each cell. This results in a module production capacity of 880MWh/year.
Globally, automation and equipment development in this project will enable a cost reduction of the whole battery pack of 15%. Having in mind that only 24% of the cost is related to the module/pack manufacturing (60% are materials components and 16% are transports and others), it represents a major step in the way to mass production. Market growing will also pull down the prices of the materials, and it will open the way to the mass production at competitive costs.
An internal survey to organize potential dissemination activities was finished in Feb 2015 (launched in Jan 2015).The main conclusions of this survey were:
This survey was and is useful in order to know which partners are interested in which fields of dissemination so that there could be collaborations between partners after the project: how, when, what was defined through this survey.
Share of knowledge with respect to interesting fairs and events as well as European platforms
White Paper (WP) was launched (continuation of ELIBAMA project) as a specific activity to be fulfilled and replaced any further training activity or e-learning, since there was not agreement on how/who should take care of those post-Greenlion activities and found that the WP was an effective and productive way to share the knowledge of the project.
