It occurs naturally as the mineral theophrastite, which is very rare. Nickel hydroxide is used in rechargeable battery electrodes. Nickel is a chemical compound with the atomic number 28. It is found abundantly in nature in laterite ore minerals, such as limonite, garnierite, and pentlandite. Nickel has a biological role and is found in certain enzymes, including urease, hydrogenase, methylcoenzyme M reductase, and carbon monoxide dehydrogenase. (L40, L41, L44)"}]
