Bifunctional Electrocatalysts Materials for Non-Aqueous Li–Air Batteries
Round 1
Reviewer 1 Report
This manuscript is about a review on bifunctional electrocatalyst materials for Li-air batteries. This manuscript can be accepted after minor correction.
1. I would suggest to include “materials” in the title. Also, it should be “non-aqueous”.
2. Please provide the architecture of Li-air battery for better understanding.
3. Standardize the term of Li-air batteries (either LABs or Li-O2 batteries).
4. Figures provided in the manuscript have not been mentioned in the text. Therefore, it does not give any meaning to the manuscript.
5. Why transition metal chalcogenides? Normally chalcogenides refer to chalcogen elements like S, Se and Te even though oxygen is in the same group of them. Section 3.3 can be renamed as Transitional Metal Oxides and section 3.3.3 to be renumbered to 3.4.

Responds to the reviewers’ comments:
Reviewer #1-Comment 1: I would suggest to include “materials” in the title. Also, it should be “non-aqueous”.
Response: Thanks for your kind suggestion. We have changed the title to Bifunctional electrocatalysts materials for non-aqueous Li-air batteries
Reviewer #1-Comment 2: Please provide the architecture of Li-air battery for better understanding.
Response: Thanks for your kind suggestion. We have added fig. 1 for understanding.

Reviewer #1-Comment 3: Standardize the term of Li-air batteries (either LABs or Li-O2 batteries).
Response: Thanks for your kind suggestion. We have unified this statement as LABs.
Reviewer #1-Comment 4: Figures provided in the manuscript have not been mentioned in the text. Therefore, it does not give any meaning to the manuscript.
Response: Thanks for your kind suggestion. All the figures are mentioned in the text now.
Reviewer #1-Comment 5: Why transition metal chalcogenides? Normally chalcogenides refer to chalcogen elements like S, Se and Te even though oxygen is in the same group of them. Section 3.3 can be renamed as Transitional Metal Oxides and section 3.3.3 to be renumbered to 3.4.
Response: Thanks for your kind suggestion. We have revised the title of section as you point out.
Section 3.3 Transition Metal Oxides
Section 3.4 Other kind of transition metal compounds

Reviewer 2 Report
The reviewed work is an extensive review of cathodic materials for lithium-air batteries (LABs). While it is well organized and contains all major ORR carbon and non-carbon catalysts investigated for use in LABs, the manuscript requires a very serious correction of grammar and style as it is not suitable for publication in the present form.

Reviewer #2: The reviewed work is an extensive review of cathodic materials for lithium-air batteries (LABs). While it is well organized and contains all major ORR carbon and non-carbon catalysts investigated for use in LABs, the manuscript requires a very serious correction of grammar and style as it is not suitable for publication in the present form.
Response: Thanks for your kind suggestion. We have revised the WHOLE manuscript carefully and tried to avoid any grammar or syntax error. In addition, we have asked several colleagues who are skilled authors of English language papers to check the English. We believe that the language is now acceptable for the review process.
Round 2
Reviewer 2 Report
This is a revision of a previously submitted manuscript. Although the grammar and style have been improved significantly, there are still present sporadic grammar glitches here and there, e.g., "circulations" on p. 13 should be changed to "cycles".
