    Wikipedia a nikkel oxidra:

    "Applications and reactions

    NiO was also a component in the Nickel-iron battery, also known as the Edison Battery, and is a component in fuel cells. It is the precursor to many nickel salts, for use as specialty chemicals and catalysts. More recently, NiO was used to make the NiCd rechargeable batteries found in many electronic devices until the development of the environmentally superior Lithium Ion battery."

    Szoval ez egy Edison ota ismert technologia... csak eppen nem tul hatekony meg olcso.
