Recycling of nickel-cadmium batteries
Abstrak
The electrodes of Ni-Cd batteries contain heavy metals such as Ni, Cd and Co, which must be recycled to solve environmental problems. At the same time, Ni and Co obtained during the process have significant economic value and belong to strategically important metals (Critical Raw Materials according to the EU classification). The paper presents a literature review of procedures for recycling Ni-Cd batteries with a special reference to leaching with sulfuric acid as the most commonly used procedure. This simple hydrometallurgical technology is ideal for small and medium-capacity plants because it does not require the expensive equipment used in pyrometallurgical technology that applies carbothermal reduction at a high temperature. The paper also presents the results of the physicochemical characterization of the battery after manual disassembly, performed by ICP OES and SEM-EDS analyses.
