preparation example Construction

[0020] The method for preparing porous nickel with a cross-scale hierarchical porous structure provided by the application includes the following steps:

[0021] Modeling: Use software to design a three-dimensional model of the porous structure.

[0022] As an option, the software for designing the three-dimensional model of the porous structure can be Solidworks, AutoCAD or UG software, etc.

[0023] Preferably, the porosity of the three-dimensional model of the porous structure and the porous nickel product of the cross-scale multi-level porous structure in the present application can be 40-90%, for example, it can be 40%, 50%, 60%, 70%, 80% or 90%, etc., can also be 45%, 55%, 65%, 75% or 85%, etc., and can also be any porosity value in the range of 40-90%.

[0024] It is worth noting that in this application, the porosity in the three-dimensional model of the porous structure can be uniformly the same porosity value (that is, the porosity in different regions is the same),...
