From May 2022 to October 2023, a concept of a Product Passport has been developed using its block chain infrastructure. A total of 4 full battery packs, and more than 40 modules has been transferring between the partners to cover their activities on repair, disassembly, and pre-mechanical treatment. Partners also focused on the development of a methodology for second life applications of EV batteries, designing a tool for the characterization of the SoH of the batteries and modules in 15 minutes. A prototype for a second life energy storage system has been produced from EV battery consisting in a cabinet of 80 kWh. Battery repair and modules replacement has been successfully achieved for 3 EV models above 14 studied. A risk analysis was performed to anticipate, prevent, detect and act on mechanical, thermal, and electrical possible issues from vehicle to cell, safe deactivation and handling. Principal focus on the first period was on the manual deactivation and dismantling. All the components were inventoried, and the protocols served as guidelines reported on D3.3. SQL database, that includes relevant information of different battery packs. Besides, and AI algorithm was developed considering the dismantling steps. An artificial vision model was implemented and trained for screw detection. An evaluation of the robot’s tools for dismantling was also performed. An analysis of all the compounds and the different treatment routes was carried and determined that 81% of compounds could be recycled. This analysis does not consider the modules dismantled. Innovative process deactivation of EV battery cells and modules based on inert fluid were successfull. Inert crushing and mechanical separation have been also successful at pilot level and produced different black mass samples. Current work is dedicated to the separation of graphite and cathode materials using flotation.. Electro-hydraulic fragmentation has been realized as innovative delamination approach for discharged domestic batteries and reach to extract high purity black mass from this stream. The leaching and recovery of Mn from black mass has been optimized for different NMC chemistries. ChCl-based Deep Eutectic Solvents as inorganic acid alternative has been evaluated for black mass leaching. The performances of the solvent extraction process for the recovery of Co and Mn have been evaluated at micro pilot level. The process parameters were optimized and recovery yields of greater than 99 % were obtained for the recovery of Mn and Co. The process was validated for scraps and optimisation is currently underway for conventional black mass. Besides, liquid membranes and flat and hollow fiber Polymer Inclusion Membranes (PIMs) for Co and Ni recovery were developed. A screening of extractants and feed/strip solutions conditions was also carried out. Li recovery process using electrochemical technology is currently studied under a flow system. The synthesis of reference materials LNMO, NMC811 and NMC91/21/2. NMC91/21/2 have been upscaled up to 100Kg using recycled sulphates, as well. Recycled RMs will be also use in other pigment for printed electronic industry. An eco-design macro rules document is available that considers parameters such as time saving, cost saving and environmental impacts. A first version policies’ inventory has been created related to collection, transport, repair, reuse and recycling of batteries. The mapping of the processes has been started at project level and at pilot level to define BATRAW’s circular business models.
