Batteries technologies workshop

1. SASLAB Sustainability Assessment of Second Life Application of Automotive Batteries Batteries2020 Workshop JRC Exploratory Research 2016 Franco Di Persio, and Andreas Pfrang (JRC, IET - F02, Petten ) Silvia Bobba, Fabrice Mathieux (JRC, IES – H08, Ispra ) Maarten Messagie ( VUBrussels ) 1

2. - Analysis of existing / pilot systems Literature analysis International projects (e.g. SUNBATT, Second Life Batteries project, AlpStore , ABattRelife , etc.) LCA methodological approach Key parameters for assessing the environmental performances of second-life applications of batteries (e.g. lifetime, DOD, temperature, chemistry, cycles, etc.) Different reuse scenarios for EVs batteries Definition and initialization of re-purposing systems 1

3. - Analysis of existing / pilot systems Understanding of the whole chain of processes  Characterization of current practices/processes to clearly define and understand the system in order to establish the system boundaries (technological, geographical, etc.) Definition and initialization of re-purposing systems 2

4. - Analysis of existing / pilot systems Understanding of the whole chain of processes Identification of the key actors of the battery chain Contact/interview/collect information from key actors of the battery chain Definition and initialization of re-purposing systems 3

5. Definition and initialization of re-purposing systems - Analysis of existing / pilot systems Understanding of the whole chain of processes Questionnaires (developed based on Ardente et al. 2015) Car companies Waste batteries collectors Repurposing companies Actors using re-purposed batteries Experts Interviews outcome CRF (03/2016 ) Renault: limited feedback Peugeot: no feedback Sitbat : we are in contact with them 4

6. Definition and initialization of re-purposing systems - Analysis of existing / pilot systems LCA literature review There are already examples of LCA of EVs batteries ( even from-cradle-to-grave) Different scenarios of energy storage are considered: Stationary storage Intermittent Renewable Energy Supply (RES) systems Residential Demand/Response service 5

7. Definition and initialization of re-purposing systems - Analysis of existing / pilot systems LCA literature review Li-ion batteries (LMO / LFP / ) Impact categories: Climate change Mineral resource depletion Human Toxicity Particulate Matter Formation System boundaries : Production process (raw materials extraction, transportation, assembly) Use phase  first life / second life / key parameters (e.g. temperature / degradation / lifetime / DOD / …) EoL  usually recycling process is considered 6

8. Definition and initialization of re-purposing systems - Environmental assessment: open questions Functional unit Battery chemistry (LFP, LMO, NCA) and battery key parameters System boundaries based on the literature review and the interviews outcomes To be clarified soon: First life : from literature? Second-life: our data Recycling /disposal pha se: from literature? Definition of the base-case scenario and of the comparison scenarios Impact categories : ILCD/PEF recommendations will be used for the LCIA Specific impact categories 7

9. Definition and initialization of re-purposing systems - Economic assessment: open questions Share of market / evolution Existing economic assessment concerning batteries second-life application (e.g. Saez et al., 2015; Heymans et al., 2014; Gruber et al., 2011; Viswanathan and Meyer, 2011 ; Wolfs, 2010 ; …) Global EV Outlook (2015) 8 Saez -de- Ibarra (2015)
