A continuation of our project involving the extraction of lithium from lithium-ion batteries.
In the last video, we extracted the electrode materials from around 160 Wh of Li-ion batteries, and heated it all up in a furnace to break everything down. In this video, we dissolve the resulting mass in sulfuric acid, and work on precipitating the undesired metals from solution. Things don't quite go as planned, but we were at least able to extract around 20 g of manganese dioxide from the mixture.
Overall, this wasn't successful in getting any of the lithium, so there'll probably be a third video on this project some day. Either way, we'll definitely be extracting the cobalt and nickel from the precipitate we made at some point in the future.
