Recent Advancements in Selenium-Based Cathode Materials for Lithium Batteries: A Mini-Review

Round 1

Reviewer 1 Report

I have reviewed the manuscript titled " Advanced Cathode Material Design for High-Performance Lithium-Se Batteries: Recent Advances". Authors have made comprehensive attempts to summarize the works on Li-Se batteries. I think this manuscript can be accepted for publication after addressing the following comments. 

1. Tile of the manuscript should be revised
2. Sub and superscript of SI units should be correct i.e in the abstract. Carefully, check throughout the manuscript. 
3. Some gramma and phrase errors should be carefully checked and corrected throughout the manuscript.
4. Working principle of  Li-Se batteries should be elaborated in the introduction section with the help of references and figures.
5. I can see, that the authors have only focused on electrochemical parts/images. I would suggest authors to include structural characterizations of the Se/Host materials used for corresponding electrochemical characterizations. 
6. The future outlooks/recommendation should be provided in the form of bullet points instead of paragraphs.

Reviewer 2 Report

The review article entitled " Advanced Cathode Material Design for High-Performance Lithium-Se Batteries: Recent Advances" by Mustafa Khan et al. is quite interesting. However, the article needs to be improved further.  Therefore, I recommend major revision.

1. What is the different points (novelty) of your review from the already published review articles in the same topic?

2021 - https://doi.org/10.1002/sus2.26 - Advanced design of cathodes and interlayers for high-performance lithium-selenium batteries

2017 - https://doi.org/10.1039/C6SE00094K - The rise of lithium–selenium batteries

2021 - https://doi.org/10.1002/adma.202003845 - State-Of-The-Art and Future Challenges in High Energy Lithium–Selenium Batteries

2019 - https://doi.org/10.1016/j.ensm.2019.05.013 - One dimensional nanostructures contribute better Li–S and Li–Se batteries: Progress, challenges and perspectives

2. Introduction needs to be more focused and attractive so that broader audience can be pulled towards paper.
3. The author did not cite the articles from the “Electrochem” journal. Include more references (at least 10 % form the overall references) from the “Electrochem” journal.
4. How dimensional-based materials improve the electrochemical performance as used for electrode. Explain in the separate section for different dimensional of cathode materials and its impact
5. In section 5, extend this section by describing more with recent results
6. Few works on Mxene can be discussed in this manuscript such as

2020 - https://doi.org/10.1039/D0NR02296A - Functionalized MXenes as effective polyselenide immobilizers for lithium–selenium batteries: a density functional theory (DFT) study

2020 - https://doi.org/10.1002/aenm.202000446 - Interface engineering of MXene composite separator for high‐performance Li–Se and Na–Se batteries

7. Finally the outlook should also be concise focusing on the various other future prospects and possible applications of the synthesized materials to other research areas too.

Reviewer 3 Report

          Selenium (Se)-based cathodic materials reported in the literatures are collected, analyzed, organized and compared in this review manuscript. Some comments are given in the followings.

1. Some formats in the abstract of manuscript should be revised, such as “mA h” should be “mAh”, “cm-3” should be “cm^-3”.
2. Some abbreviations in the manuscript should be given for the convenience of readers, such as LCO, NCA, NMC, … .
3. Some figures quoted from the literatures are not clear, the resolution should be improved, such as Figs. 1, 2, 4 and 5.
4. The title of y-axis in Fig. 1(a) should be “Discharge Capacity Retention” but not “Discharge Capacity”.
5. It is better to give some tables for summarizing and comparing the properties of the similar kinds of composite materials.
