Round 1

Reviewer 1 Report

This manuscript studies pulse charging algorithm, and compare it with the commonly applied benchmark constant current-constant voltage (CC-CV) charging method. I think this manuscript deliver important insight and information on pulse charging algorithm for Li-ion polymer batteries. But this manuscript should be revised based on the following comments to further improve the quality.

The experimental conditions are not clearly shown in the manuscript. The experimental section should be included. What type of Li-ion polymer battery was used? Cathodes, anodes, and electrolytes should be specified. For the results such as battery charge and energy efficiency, the methods used should be explained in the manuscript.

 

Author Response

The details of experimental procedures are described in previously published manuscripts. However, the authors have accepted the reviewer’s comments and have added a brief summary of the experimental procedures to enhance clarity.

The specific type of Li-ion polymer battery used, including anode and cathodes, and electrolytes should be specified.

The methods used to calculate battery charge and energy efficiency are described in previously published manuscripts. However, the authors have accepted the reviewer’s comments and have added a brief description of the methods used to calculate battery charge and energy efficiency.

Reviewer 2 Report

1.Compared to other Li-ion technologies, including using liquid electrolytes or all-solid-state electrolytes, what are advantages of using polymer electrolytes? What is the motivation? The authors should provide more discussion on the motivation and significance of the studies in the field. 

2.The authors are suggested to provide a table summary regarding critical parameters/performance improvement, such as battery configuration (polymer electrolytes), voltage range, current density, charge time, efficiencies and cycle life, on state-of-the-art studies about pulse charging.

3.In the section 4, the authors are suggested to provide guidelines for the future studies on pulse charging algorithm.

Author Response

Compared to other Li-ion technologies, including using liquid electrolytes or all-solid-state electrolytes, what are advantages of using polymer electrolytes? What is the motivation? The authors should provide more discussion on the motivation and significance of the studies in the field.

The advantages of LiPo batteries has been expanded upon and emphasized in the Introduction.  Similarly, the motivation and significance for this study has been expanded upon in the Introduction.

The authors are suggested to provide a table summary regarding critical parameters/performance improvement, such as battery configuration (polymer electrolytes), voltage range, current density, charge time, efficiencies and cycle life, on state-of-the-art studies about pulse charging.

A table summarizing the key performance characteristics has been included.

3. In the section 4, the authors are suggested to provide guidelines for the future studies on pulse charging algorithm.

We thank the reviewer for this comment. We have included a few remarks regarding future studies aimed art improving pulse charging algorithms.
