Lithium battery renewal: co-culture using Aspergillus niger and ...
The percent yield from the lithium-ion battery after fungal bioleaching using Aspergillus niger should equal around 100% Cu, 95% Li, 70% Mn, 65% Al, 45% Co, 38% Ni (Horeh, Mousavi and Shojaosadati 2016). Citric acid is the most prominent lixiviant, allowing for the extraction of the lithium.
