Hi, you may choose the nickel foam with thickness of 1-2 mm.

Pls, find the link for Nickel foam substrate which is ideal for the battery/supercapacitor fabrications.

Nickel Foam for Battery Cathode Substrate (1000 mm length x 300 mm width x 1.6 mm thickness)

Hi, 1.6 mm thickness of Ni foam is a right combination for metal oxide based super-capacitor application.

Hi

I would like you to answer my question

I used aluminum foam with PCM

how can I explain porosity(0.92), pore density(PPI=10), permeability and.. for metal foam in fluent in Ansys Fluent ??
