Combining 3D Printing and Electrochemical Deposition for Manufacturing Tailor-Made 3D Nickel Foams with Highly Competitive Porosity and Specific Surface Area Density

Round 1

Reviewer 1 Report

Thank you for inviting me to review the article entitled “Efficient Manufacturing of Nickel Substrates, via Electrochemical Deposition on 3D Printed and Subsequently Dissolved Support, with Highly Competitive Porosity and Specific Surface Area Density”. The control of non-active substances in lithium ion batteries can effectively improve energy density. The research direction of the manuscript has certain significance, but it still needs to be improved. Therefore, my opinion is acceptance after major modifications. Following are my comments on this manuscript.

1. The title of the manuscript is too long and should be refined.

2. The author should take commercial current collectors and nickel foams as comparisons. Analyze the advantages and disadvantages of the three current collectors, including cost, conductivity, and so on.

3. The current collectors prepared by the 3D printing technology in the manuscript may be applicable in the coin cells but whether it can be prepared and applied to pouch cells.

4. There are large holes current collectors proposed in the manuscript. How to achieve the slurry coated on current collectors during the preparation of the electrode.

 

5. Whether the prepared nickel foams have the mechanical strength required as a current collector.

Title: Efficient Manufacturing of Nickel Substrates, via Electrochemical Deposition on 3D Printed and Subsequently Dissolved Support, with Highly Competitive Porosity and Specific Surface Area Density

 

Metals

 

The manuscripts is devoted to synthesis of porous 3D Ni substrates by electrodeposition of Ni on the 3D polymer substrate followed by dissolution of the polymer scaffolding.

 

The authors postulate obtaining porous metal foams, therefore, in my opinion, they should present in the introduction section more examples of methods of obtaining them. Moreover, they should compare (preferably in a table) some parameters (e.g., porosity, surface area) of such metallic foams described in the literature with those synthesized in this work.

 

Unfortunately, there are no mechanical strength tests for the porous metallic foams produced. These may be useful especially when practical applications are considered and discussed.

 

The notation of the chemical formula of boric acid is incorrect. It must not be written as B(OH)3 (line 154 and table 1). Such notation suggests a hydroxide! The chemical formula of boric acid is H3BO3.

 

The chemical formula of a hydrated salt (line 155 and table 1) should not be written with an asterisk but with a dot.

 

The list of cited literature is extremely short. Please supplement the literature list in the thematic scope of the work.

 

I recommend this paper for publication after minior revision.
