Heavy metal cobalt is a crucial raw material for lithium-ion batteries, though it creates a substantial degree of negative impact to humans and the natural environment, and numerous microorganisms have stayed away from cobalt. Scientists have recently discovered that microorganisms create a layer of “iron shield” to protect themselves from being in contact with toxic cobalt, and the discovery may help with the development in the recycling of lithium ion batteries and the decontamination of heavy metals. ... more
