Abstract Among high-capacity materials for the negative electrode of a lithium-ion battery, Sn stands out due to a high theoretical specific capacity of 994 mA h/g and the presence of a low-potential discharge plateau. However, a significant increase in volume during the intercalation of lithium into tin leads to degradation and a serious decrease in capacity. An
Because Cobalt is an indispensable component in commercial Lithium-ion batteries and thermal metallurgy is more effective at recovering Cobalt than Lithium, the cost estimation of this recovery methodology is determined mainly dependent on the percentage of cobalt used in Lithium-ion batteries and the variation in the cobalt market value and Co-free

Moreover, even though a sodium-ion battery with this hard carbon negative electrode would in theory operate at a 0.3-volt lower voltage difference than a standard lithium-ion battery, the higher capacity of the former would lead to a much greater energy density by weight (1600 Wh/kg versus 1430 Wh/kg), resulting in +19% increase of energy density.
