Recent Progression and Opportunities of Polysaccharide Assisted Bio-Electrolyte Membranes for Rechargeable Charge Storage and Conversion Devices
Round 1
Reviewer 1 Report
The manuscript electrochem-2265019 covers the development of polysaccharide-based membranes for storage and conversion devices. The topic is of high importance and soundness to be published in this journal. This review is also well-organized but it needs extensive editing in the English language. In addition to that, the quality of the images needs to be improved. Abbreviations must also be spelled out in the text to facilitate the reader's understanding.
Since it is a review, it should contain more recent references. And in relation to the polysaccharides described, it is not justified to have a small section dedicated to cellulose acetate, but not to have one for cellulose in general. Since cellulose is the most abundant and there are many recent works for its application in this area, it should be mentioned here.

Reviewer 2
The review article entitled: Recent progression and opportunities of polysaccharide assisted bio-electrolyte membranes for the rechargeable charge storage and conversion devices are well written, but there are some major concerns before publishing it in Electrochem.
Query 1:
Revise the abstract in a vivid manner.
Reply:
As per the suggestions of the reviewer, abstract has been revised.
Query 2:
The direct interaction of active but electrodes and solid electrolytes will influence the interfacial problems, how?
Reply:
The direct interaction of electrode and electrolytes heavily influence the electrochemical performance of the device and interface as well. This may be due to physical contact of two solid materials and forming a good interface is quite hard and challenging also.
In the commercial devices, electrolyte liquids absorb on surface of the electrode and ionic transportations occurs in a more rapid manner whereas solid-state polymer devices, ionic transportation across the interfacial region is not easier and difficulties are co-existed including poor diffusivity, mobility and conductivity, which is due to the physical contact between electrode/electrolyte and hinders the device performances.
Query 3:
How plasticizer helps to increase the conductivity of the lithium-ion conducting membrane?
Reply:
Addition of plasticizer significantly improves the ionic conductivity due to plasticization effect. Plasticizer has high dielectric constant to dissociate a greater number of ions. As an outcome, increase in larger number of mobile ions, leads to the enhancement in conductivity. Also, reduce the crystallinity of the Li-ion conducting electrolytes which helps to enrich the flexible nature of electrolytes and improves the amorphous character of the electrolytes. Ionic transportation is much easier in the amorphous regime.
Query 4:
How the conductivity is varied with respect to changing the salt? Justify your explanation.
Reply:
The lattice energy and molecular weight of the ionic dopant salts influence some of the parameters like ionic conductivity, transference number and window of electrochemical stability of the electrolytes significantly. These changes occurred only due to the ion dissociation factor and lattice energy of the incorporated salts. Here, lattice energy is the most important factor in the crystalline ionic compound. It is directly proportional to the product of the ion charges and inversely proportional to the internuclear distance. Moreover, it depends on the crystal structure and is inversely related to the size of the ions. The ease of dissolution of an electrolyte in the polymer depends on the lattice energy of the salt. The lower lattice energy results in the easier dissolution and rapid dissociation of cations and anions. The added salt has been dissociated into cations and anions.
Query 5:
Clarify the possibilities to increase the mechanical stability of the membrane?
Reply:
Introduction metal oxide particles in polymer electrolytes as a filler and comes under the composite polymer electrolytes category. The incorporation of nanoparticles into the host, ionic conductivity of the same has been improved via percolating interfacial effect and providing excellent mechanical strength to the polymer electrolytes.
Query 6:
Check the typographical errors throughout the manuscript.
Reply:
As per the suggestions of the reviewer, utmost care has been considered to rectify the typographical errors and revised it accordingly.
Query 7:
What are the factors influencing the energy storage properties of the devices?
Reply:
In the solid-state batteries, interfacial problems are yet to be solved. The influencing parameters are, lower ionic conductivity and ion transference number, higher interfacial resistance, lack in the understanding of the electrode/electrolyte interface, profile of the interfacial chemical potential and electrode reactions while transfer of ions between electrode and electrolyte counterparts.
