Anna Siekierka is addressing the challenging issue of lithium-ion battery (LIB) effluent containing hazardous metals like cobalt, lithium, and nickel by proposing a zero-waste process for metal recovery. Her solution involves using reverse electrodialysis with an ultra-selective cobalt exchange membrane, allowing for cobalt recovery and simultaneous energy harvesting from the potential differences across the membrane stack, thus providing both metal fractionation and renewable energy generation from battery effluents.

Anna Siekierka is an Assistant Professor at Wroclaw University of Science and Technology. She is interested in applying electro-membrane processes for the selective separation of metal ions and energy extraction and specialises in developing ultra-selective ion exchange membranes and spinel-type sorbents to fractionate brines and battery effluents. Anna is a board member of the Polish Membrane Society. Privately, she composes perfumes and enjoys listening to music.
