(2) solution being heated to 50-100 DEG C, moisture is constantly evaporated to thick gel state.
(3) gel is heated to 140-290 DEG C, gel generation self-propagating combustion, obtain the loose powder of black.
(4) gained powder is joined in solvent and clean, be dried.
In the step (1) of preparation method of the present invention, the nickel salt of described solubility is one or more in nickel nitrate, Nickel dichloride. or nickel sulfate.
In the step (1) of preparation method of the present invention, described organic-fuel is one or more in citric acid, glycine or carbamide, and the molal quantity of added organic-fuel is 0.4-0.9 times of nickel ion molal quantity.
In the step (1) of preparation method of the present invention, described comburant is ammonium nitrate, added nitric acid by molal quantity is nickel ion molal quantity 0. 001-1 times.
In the step (3) of preparation method of the present invention, described gel also can be ignited by naked light or microwave, then self-propagating combustion occurs.
In the step (4) of preparation method of the present invention, described cleaning solvent is one or more of deionized water, ethanol, propanol, acetone etc..
The invention have the advantage that present invention process the most easily operates, cheaper starting materials is easy to get, prepared carbon cladding NiO/Ni, can significantly improve the crystalline quality of NiO/Ni, and one layer of carbon of Surface coating.Carbon cladding and Ni can significantly improve the electric conductivity of NiO, the shortcoming overcoming metal conductive oxide difference, can play significant performance improvement for its application in lithium ion battery, ultracapacitor etc..Common multistep complicated technology, process cycle length or expensive device etc., low cost can be avoided by the technique of the present invention, be suitable for industrialization large-scale production.
