NICKEL AND NICKEL COMPOUNDS
Nickel and nickel compounds were considered by previous IARC Working Groups, in 1972, 1975, 1979, 1982 and 1987 (IARC, 1973, 1976, 1979, 1982, 1987). Since that time, new data have become available, and these are included in the present monograph and have been taken into consideration in the evaluation.

Nickel hydrogen gas batteries: From aerospace to grid …
The aerospace energy storage systems need to be highly reliable, all-climate, maintenance-free and long shelf life of more than 10 years [5, 7]. In fact, since the mid-1970s, most of the spacecrafts launched for GEO and LEO service have used energy storage systems composed of nickel–hydrogen gas (Ni–H 2) batteries [6, 7, 8].

Nickel-based Batteries | Characteristics & Applications
Nickel Metal Hydride Battery. A nickel metal hydride battery, NiMH, is a rechargeable battery with a positive electrode made of nickel hydroxide and a negative electrode made of a metal hydride (a hydrogen-absorbing alloy). The NiMH battery was commercially introduced in 1989 and was mainly used as a power source in portable personal computers.

How to Do Nickel Plating at Home
Follow the instructions on your nickel plating stripping agent to heat it up. Typically, you heat the liquid up to around 140 °F (60 °C) to activate it. Then, soak your nickel-plated object in the solution for 10-15 minutes. Remove it with some tongs or a wooden spoon, rinse the object off thoroughly, and you're done!
