Abstract
The large scale recycling of lithium ion batteries (LIBs) is essential to satisfy global demands for the raw materials required to implement this technology as part of a clean energy strategy. However, despite what is rapidly becoming a critical need, an efficient and sustainable recycling process for LIBs has yet to be developed. Biological reactions occur with great selectivity under mild conditions, offering new avenues for the implementation of more environmentally sustainable processes. Here, we demonstrate a sequential process employing two bacterial species to recover Mn, Co and Ni, from vehicular LIBs through the biosynthesis of metallic nanoparticles, whilst Li remains within the leachate. We investigated bio-selectivity between Co and Ni using proteomics, confirming control of the biological response. Our approach determines the principles and first steps of a practical bio-separation and recovery system, underlining the relevance of harnessing biological specificity for recycling and up-cycling critical materials

Title
Proteomics data
Description
Proteomic data associated to the cellular response of Desulfovibrio alaskensis G20 to Co(II) and or Ni(II). Experimental design: 1)Three different metal combinations were applied: single metal treatments, only Co(II) or Ni(II), and bimetallic (Co(II) and Ni(II) at equal concentrations). 2) Two different metal concentration levels (10 mg and 100 mg/L) 3) Two different incubation time points (2 and 20 h) to investigate the dynamics of proteins production.
