| Abstract Scope |
Landfilling of spent alkaline batteries is considered as more attractive than recycling if economic perspective is the main factor taken into account. The current study explores the potential use of solar thermal energy in recovering valuable Zn/ZnO from the batteries in attempt to improve the economic competitiveness of the recycling process. The blackmass obtained from the batteries’ anode and cathode, mixed with carbon from End-of-Life lithium batteries at various concentration, were subjected to carbothermal reduction at 1100°C in a solar thermal simulator reactor under argon. It was found that high purity Zn/ZnO powder can be recovered from the blackmass, leaving valuable MnO in the reactor. The increase in argon flow was found to decrease the particle size of the Zn/ZnO powder, where the maximum size of 650nm obtained at 2L/min argon. The use of solar thermal energy reduces the production cost, while the decrease in particle size improves product value. |
