PUBLIC DELIVERABLES

Abstract :

Because of the volume and the stored energy, safety requirements for large Lithium-Ion batteries (LIB) are significantly higher than safety requirements for consumer cells and cells for hybrid applications. These safety requirements also apply for the recycling process of Lithium-Ion traction batteries. An efficient and safe recycling process of LIB is necessary to counteract the scarce availability of raw materials. To ensure an efficient and safe recycling process, a safe take back process of LIB subject to all EU legislation needs to be developed.

Goal of this task is the quantification of the risks which occurs during handling, storage and transportation of LIB in order to achieve a secure take back of LIB.

To achieve this goal, two workshops together with the involved partners in this task, Umicore, SNAM, EDI-Veolia, Daimler, Renault and Fraunhofer were conducted. In the first Workshop, required process steps and their critical aspects were identified and discussed. Different logistic options were studied and possible partners involved in the take back process were determined.

Based on that knowledge a second workshop was hold. The target of this workshop was the quantification and minimization of the risks in the take back process of LIB. Therefore a FMEA risk analysis, based on a modular 12- staged take back process, which was defined in advance with the project partners, was conducted. For the process steps in total 220 functions were identified and possible failures for the functions were determined and structured in failures caused by human, material, tools, environment and methodology. Altogether 1014 possible failures for the entire process were identified. The most safety relevant and risky steps were: removing of the battery from the car, diagnosis and packaging. These steps provide the basis for all subsequent process steps and in these steps, the most failure causes exist. The modularity of the FMEA analysis allows the modification according to any future development in the take back process of batteries and therefore creates a baseline and a framework for risk analysis.

Furthermore checklists for the partners involved in the take back process were developed.

These checklists offer information whether a partner dealing with LIB is suitable and qualified and provides self-control for the actors

 


 

Abstract:

Nowadays, forecast sales figures for (hybrid) electric vehicles are promising. The batteries in those vehicles which are specific Lithium-Ion batteries need to be properly recycled at their end of life. Today the existing recycling processes are either a treatment by hydrometallurgical or by pyrometallurgical way. Nevertheless when a battery is recycled several measures need to be taken. Indeed, there are risks caused by high voltage and current of the battery. So, these measures consist in a diagnostic of the state of charge of the end of life batteries followed by a fitted discharge. This first step aim making safety the battery for the following steps which are the dismantling and the recycling process. Two main methods of electric discharge may be used according to the state of battery : resistive discharge or electrolytic discharge.


Abstract:

Deliverable D7.2 deals with the development and implementation of a Public Website for ELIBAMA Project.


Abstract:

At the end of the project, a stakeholder conference has been organized by the project’s partners in order to present to the community the key findings of the ELIBAMA project. This event took place in Newcastle on the 14Th of September 2014.


 Abstract:

At the end of the project, a white paper on electrodes and cells manufacturing processes has been prepared by the project’s partners in order to disseminate the project’s results to the community. The document has been made available on the project’s website and send by e-mail to the identified stakeholders.
