Better recycling methods for batteries are therefore urgently required. At TU Wien, researchers have developed a process that can be used to recover nickel from spent nickel-metal hydride batteries.

researchers at TU Wien in Austria have found a way to recover nickel from spent nickel-metal hydride batteries (Ni-MH). By repurposing battery waste and using aluminum foil, the team developed a ...

(NiMH) A rechargeable battery technology that has approximately 30-50% more charge per pound than nickel cadmium. Introduced in the early 1990s, it uses nickel and metal hydride plates with ...

Some of the first Sony Discmans included rechargeable batteries. These batteries were nickel metal hydride batteries (because of the technology of the time) and are now well past their service life.

30 years ago, options were limited to lead acid, nickel cadmium, and nickel metal hydride batteries. These were heavy, with low current output, poor capacity, and incredibly slow charge times.

Battery waste is a serious environmental problem: it contains substances that pose a threat to both human health and ecosystems. At the same time, however, they also contain valuable materials ...
