Project Title

Polymerization of Solid-state polymer electrolyte for battery applications.

Project Area of Specialization Electrical/Electronic EngineeringProject Summary

An electrolyte is a substance or chemical, which is used to store and transmit electricity, mostly used in energy storage devices. Electrolytes are used in multiple applications, including, metal extraction, and production of non,.n-metals, metal refining, electroplating, production of chemicals, batteries. There are specified redox reactions in energy storage which includes the electrodes configuration, electrolytes, and energy supply, which further transmit ions through the system for different outcomes, the electrode configuration has anodes, cathodes, and electrolyte, it is as obvious that direct current flowing in one direction through the metals recorded resistance as compared to the opposite direction. The power is produced electrochemically by passing a hydrogen-rich gas through an anode and air over a cathode introducing an electrolyte in between to enable the exchange of ions.

The classification of an electrolyte depends upon the extent to which the electrolyte can ionize the electrolyte may be strong or weak, The strong electrolyte contains the compounds having a higher extent of ionization in an aqueous solution and a great extent of current transmission, The weak electrolyte has weak ionization in aqueous solution and very small extent current transmission, various chemical compounds are used as an electrolyte, some commonly used electrolytes are sodium chloride, nitric acid, sulfuric acid, and sodium acetate.

The most common electrolyte solution is used along with NaCl is more readily used than some other costly electrolytes, like Li, Cl, Na, etc, along with aqueous solutions and solid gels[2]. This work is focused on using sodium ions in polymer gel electrolytes in batteries. Lithium-ion batteries were successfully tested for automotive applications, electrical applications, and biosensing. Na ions are reported more efficient and have higher mobilization in polymer structures than Li-ions used. Na-ion technology has higher effectiveness, the use of Na can be prolonged to fit the whole spectrum of electrochemical energy storage systems, Na technology with higher energy, or high-power Na-based hybrid supercapacitors. The promising performance of Na-based energy storage systems, makes Na, the key to the coming commercial post-lithium systems. In this research, a polymer gel electrolyte will be synthesized using different chemicals and ingredients, using the Na ion as an ionic dopant which can further enhance the ionic movement in these materials, the final product will be used in designing batteries and its application. Previously produced similar material using NaCl was observed with higher electrical transmission and higher ionic conductivity, the current material will be subjected to get better capacitance satisfied the tensile strength and compressive strength, this material will be transparent and flexible in nature.

Project Objectives

Project Implementation Method

The said material will be used as an electrolyte in batteries, the carbon electrode, and steel electrolyte will be used as current collectors in battery configuration, this whole system would be considered as energy storage relevant with the dry cell systems. this system will be attached along with an electrochemical station to check the electrochemical performance of the material, including; ionic conductivity, capacitance, charge-discharge, and redox reactions by means of cyclic voltammetry. 

Benefits of the Project

Following are the major benefits and outcomes of this project:

1. It is obvious that, during the experimental work, the students of FYP will learn to operate the lab equipment, and they will be trained in software applications of data analysis and data management.

2. As the final objective of this project would be, to produce the batteries, which can later confirm the applications and could be used practically, which is beneficial for industrial applications.

3. If possible and availability of funding, the materials might be produced in bulk quantity to deliver to market from the business perspective 

4. Research article from this project will be published in any reputed journal at the end of the project

Technical Details of Final Deliverable

The final product will be in the form of a dry cell battery, which will be used as a life-size model, this battery would include the electrodes, electrolytes, connectors, and case. In the prototype model, some sort of circuits will be added to see the performance of the battery after some time of charging.
