"Vehicle battery recycling is going to be a big deal with all the electric cars
hitting the roads. What if you could do it more effectively with the power of
microbes? (via
Electrek)
“Li-ion” vehicle batteries can be any of a number of different chemistries,
with more complex cathode makeups, like NCM (LiNixMnyCo1-x-yO2), being
understandably more complex to separate into their original constituents.
Researchers and companies in the industry are hoping to find
economically-viable ways to get these metals back for both the environmental
and economic benefits a closed loop system could provide.
Researchers in the UK developed a method using two species of bacteria to
precipitate Ni, Mn, and Co from the liquid leached from cathodes. Li remained
in the liquid where it could be processed separately like that obtained in Li
brine. Mn was precipitated first by S. oneidensis MR-1, and a following step
removed Ni and Co with D. alaskensis G20. The researchers report that Ni and Co
show promise for further separation via biological methods, but more research
is required for this step."
