(Nanowerk Information) Electromobility continues to realize momentum. Accelerated by excessive gas costs, an increasing number of patrons are switching to hybrid or pure electrical autos, as proven by the most recent statistics of latest registrations. Because the variety of traction batteries will increase, the query of environmentally pleasant manufacturing and recycling processes can be turning into louder. One key facet is the function-preserving recycling of lithium-ion batteries.

The RecyLIB challenge launched in 2022 goals to set a superb instance with new processes for battery electrode manufacturing, direct recycling and built-in purposeful materials cycles.

To avoid wasting major uncooked supplies and allow a round financial system, purposeful supplies should be recovered and effectively reused as a lot as potential. “RecyLIB” goals at an built-in lithium-ion battery electrode manufacturing course of, the place the manufacturing course of is already designed to permit using recycled materials. This permits the lively purposeful materials to be recovered after the battery’s end-of-life with excessive yield turning into out there for direct reuse within the remanufacturing of electrodes.

The recycled electrode materials ought to be capable to be reintroduced straight into the electrode manufacturing course of with out affecting cell efficiency. Furthermore, crucial course of aids, reminiscent of poisonous solvents, are to be eradicated. “The RecyLIB workforce needs to take a giant step towards sustainable battery manufacturing in Europe,” stated Dr. Michael Hofmann of the Fraunhofer Institute for Silicate Analysis, who’s coordinating the challenge. “Battery manufacturing and battery recycling should go hand in hand in order that vitality and useful resource consumption in manufacturing and likewise CO₂ emissions and different environmental impacts are as little as potential.”

To attain this, the RecyLIB consortium is counting on water-based separation (electrohydraulic fragmentation and centrifugation) and sorting processes to get better the battery supplies as gently as potential, in addition to on a melting process-based electrode manufacturing which permits the waiver of poisonous solvents. The efficiency and getting older conduct of battery cells made out of major uncooked supplies and recycled purposeful materials are additionally being investigated and evaluated as a part of the challenge.

RecyLIB, with its integrative method and constant give attention to resource-conservation and energy-efficient processes, is due to this fact an vital constructing block for a sustainable, round battery ecosystem in Europe.
