6 FAQs about [Sulfuric acid and lithium battery reaction]

Does sulfuric acid roasting work for selective lithium extraction from discarded lithium-ion batteries?

Looking at the above aspect of perspective problem of selective lithium extraction from spent LIBs, present paper reports the sulfuric acid roasting, water leaching and precipitation process for selective recovery of lithium from discarded lithium-ion batteries.

Does sluggish sulfur reduction reaction affect the electrochemical performance of Li-S batteries?

However, the sluggish sulfur reduction reaction (SRR) kinetics results in poor sulfur utilization, which seriously hampers the electrochemical performance of Li–S batteries. It is critical to reveal the underlying reaction mechanisms and accelerate the SRR kinetics. Herein, the critical issues of SRR in Li–S batteries are reviewed.

How much sulfuric acid can be recovered from a battery?

An acid concentration of 0.75 mol/L was able to recover 100% of Li. Vieceli et al. (2021) tested sulfuric acid leaching with NMC battery from 0.5 mol/L to 1.5 mol/L and stated that the concentration of 1 mol/L showed better metal recovery (>80%).

Do oxalic acid and sulfuric acid recover ternary lithium-ion battery cathode materials?

By reviewing the relevant literature, there is no relevant report on the recovery of spent NCM ternary lithium-ion battery cathode materials. Therefore, the compound leaching agents of sulfuric acid and oxalic acid are the first to recover valuable metals from the cathode materials of NCM ternary lithium-ion batteries.

How much sulfuric acid is needed to react with a cathode?

Under the conditions established for the study of the variation of the S/L ratio (2.0 mol/L, 90 °C, and 2 h), and also according to the stoichiometry of the reaction of Equation (1), 0.08 mol of sulfuric acid is needed to react with the 5.3 g of oxide of the cathode.

Why are lithium batteries sluggish kinetics?

The sluggish kinetics results in the inadequate reduction of sulfur during discharging, thus decreasing the specific capacity and rate capability of Li–S batteries. Another challenge is the dissolution and diffusion of lithium polysulfide intermediates (Li 2 S n, 3 ≤ n ≤ 8) from cathodes to the electrolyte.
