Abstract

Lithium ion batteries (LIBs) and Lithium sulfur batteries (LSBs) are the most newlinepotential energy storage devices for applications such as electric vehicles and grid storage. newlineThe problem statement for these devices includes electrode degradation, unfavourable Solid newlineElectrolyte Interface (SEI), and Cathode Electrolyte Interface (CEI) formation with newlinerestricted life cycles. This research has primarily focused on the rational design and newlineengineering of novel anode, cathode, and electrolyte additives for next generation LIBs and newlineLSBs promoting the electrochemically active SEI/CEI to overcome the unstable SEI/CEI newlineformation which hinders their practical applications. The research explored different newlinematerials including and#945; MnO2, and#945; Fe2O3 based anode materials, and novel Li4B2O5 PMMA newlineelectrolyte additive material for LIBs. Also, the study extended to the use of the significant newlineand#945; Fe2O3 in the resulting LIB as cathode material for LSB, thus showing the diverse newlineapplications for the synthesized and#945; Fe2O3 material. The studied materials have exhibited newlinenotable improvements in cycling capacity, energy density, cyclic life, and coulombic newlineefficiency, proving their potential for practical energy storage applications. By integrating newlinethe fundamental physiochemical and electrochemical analysis with materials engineering, newlinethis thesis contributes to the ongoing efforts to enhance the efficiency and durability of newlinelithium based batteries. Thus, the research findings could help develop practical electrode newlinematerials with better battery performance, solving the key challenges in energy storage. newlineThe thesis dissertation begins with the Introduction (Chapter I), outlining the newlinecomprehensive overview of lithium based energy storage, which includes LIB and LSB, newlinerespectively. The literature survey that understands the current state of research on lithium newlinebased energy devices has been highlighted in the introduction followed by the specific aim newlineand objective of this research work has been included. The introduction extensively newlineexamines the operating princip
