The book "Cathode Innovations in Lithium-ion Battery Technology" by Alex Koech, Gershom Mwandila, Francis Mulolani, and Phenny Mwaanga provides a detailed analysis of Li-ion battery components, focusing on cathode materials. It covers the roles and characteristics of each component, including the cathode, anode, current collectors, binders, additives, electrolyte, separator, and cell casing. The review examines cathode materials such as spinels (e.g., LiMn?O?), nickel-rich lithium metal oxides (e.g., LiNixMnyCo????yO?), and olivine-based cathodes (e.g., LiFePO?), discussing their advantages and challenges. Spinels offer cost-effectiveness and thermal stability but face capacity fading issues, while nickel-rich oxides provide high specific energy yet encounter stability concerns. Olivine-based cathodes prioritize safety and stability but exhibit lower energy density. The review highlights the importance of thermal management and testing protocols to mitigate risks such as thermal runaway and short circuits. Finally, it scrutinizes advancements in cathode materials, strategies to address challenges, and suitable electrode materials based on electrochemical performance and capacity.
