Can H2S and CS2 be used for selective sulfidation?
While 126 industrially H2S and CS2 are commonly employed for sulfidation of oxides, their use for complete 127 sulfidation of mixed transition metal oxide catalysts17 calls into question the suitability of H2S and CS2 for 128 selective sulfidation.
Does water immersion treatment recover lithium & copper foil from slibs?
The recovery of lithium, copper foil and graphite from spent anode material (SAM) of SLIBs by water immersion treatment is a novel green method (Fig. 3b), where the stripping rate of graphite from the anode material was 100 %.
How does water remove impurities from slibs anode?
This process removes most of the impurities from the SLIBs anode since water can react with the residual soluble lithium inside the graphite to generate hydrogen and separates the SEI film from the graphite, reopening the Li + transport corridor and resuming the electrochemical performance of graphite.
Can graphite be reused as lithium battery anode materials?
The specific surface area (SSA) of the recovered graphite was enlarged, and it can be reused as lithium battery anode materials. The electrochemical experiments showed that the graphite with enlarged SSA provides more active sites for Li + intercalation. Lithium electroplating is also a green recycling process for SLIBs .
