Abstract

A hydrometallurgical method involving natural biomass waste as reductant
was proposed for the treatment of spent mixed-type lithium-ion batteries.
Results showed that almost complete dissolution of Li, Ni, Mn and nearly 90%
dissolution of Co were achieved under the optimal conditions of H2SO4 concentration of 2 M, waste tea biomass dosage of 0.3 g/g, solid/ratio of 50 g L¯¹, temperature of 90ºC and time of 120 min. The leaching kinetics was further
investigated, and the activation energies were determined to be 1.7 kJ mol¯¹,
10.3 kJ mol¯¹, 10.1 kJ mol¯¹ and 10.9 kJ mol¯¹ for Li, Ni, Mn and Co,
respectively. The cathode materials before leaching and the leaching residue
were characterized with different analytical methods. The characterization
results confirmed that the addition of the waste tea acted as reductant and
resulted in better dissolution of the metals, supporting the principles of sustainable processes by decreasing the chemical consumption and integrating
waste into a secondary use.
