Closed-loop Recycling of Nickel, Cobalt and Rare Earth Metals from Spent Nickel-metal Hydride- Batteries
Nickel-metal hydride batteries (Ni-MH) are storers of electrochemical energy, which have a higher specific storage capacity than lead or nickel-cadmium batteries. The demand for Nickel-metal hydride batteries is increasing rapidly since their market launch in the early 1990's. Today there is no suitable and sustainable recycling process to recover nickel, cobalt and rare-earth metals. The disca...
متن کاملRecovery of Metal Values from Spent Nickel-cadmium Rechargeable Batteries by Solvent Extraction Route
Spent Nickel cadmium batteries are classified as hazardous waste due to the presence of toxic cadmium in high concentration. Recycling of metal value by environmentally friendly process is the best option to obtain economical advantage and prevent environmental pollution. In the present investigation, a metal separation scheme is proposed for recovery of cadmium, nickel and cobalt from the leac...
متن کاملNickel-Metal Hydride Batteries For ZEV-Range Hybrid Electric Vehicles
Hybrid electric vehicles with significant all-electric range provide a promising alternative to zero emission vehicles (ZEVs) without the problem of the limited range of electric vehicles. Ovonic nickel-metal hydride (NiMH) batteries feature a combination of high power and energy density ideal for ZEV-range hybrid electric vehicles. A series of high-power, highenergy batteries ranging in size f...
متن کاملrecovery of nickel from spent catalysts by hydrometallurgical method
there are no appreciable amounts of nickel resources in iran; therefore, secondary resources of this element are to be more considered in future. spent nickel catalysts that are used in various industrial processes are one of them. for example nickel catalyst that is used in hydrogenation of edible oil have large amounts of nickel and they are generally supported on porous materials like silica...
متن کاملAnalytical assessment of the thermal behavior of nickel-metal hydride batteries
Introduction A three-dimensional analytical thermal model [1] is adapted to describe thermal response of Nickel-metal hydride (NiMH) batteries to heat generation during their operation. The model is based on integral-transform technique [2] that gives a closed-form solution for the fundamental problem of unsteady heat conduction in batteries with orthotropic thermal conductivities, where the he...
