nikkelhydrid
Nikkelhydrid, also known as nickel hydride, is a chemical compound with the formula NiH2. It is a solid material that is notable for its ability to absorb and release hydrogen gas, making it a useful material in hydrogen storage and battery applications. Nikkelhydrid is typically synthesized by reacting nickel with hydrogen gas at high temperatures and pressures.
The compound crystallizes in a hexagonal close-packed structure, similar to that of metallic nickel. It is a
One of the primary applications of nikkelhydrid is in nickel-metal hydride (NiMH) batteries. These batteries use
Nikkelhydrid is also used in hydrogen storage systems, where it can absorb and release hydrogen gas reversibly.
In summary, nikkelhydrid is a versatile material with applications in hydrogen storage and battery technology. Its
