| Summary: | Consumers across the world use lithium-ion batteries in some fashion in their
everyday life. The growing demand for energy has led to batteries dying quicker than
consumers want. Thus, there are calls for researchers to develop batteries that are longer
lasting. However, the initial increase in battery life over the years has been from better
engineering and not necessarily from making a better material for a battery.
This thesis focuses on the understanding of the chemistry of the materials of a
battery. Throughout the chapters, the research delves into the how and why materials
with extra nickel degrade quickly. Then, it investigates a method of making these nickelrich
materials last longer and how the chemistry within these materials are affected by the
addition of a different metal. Overall, the findings indicate that the addition of titanium
creates a more stable material because it mitigates the release of oxygen and prevents
irreversible changes within the structure of the material.
It determines that the chemistry behind the failings of nickel-rich lithium-ion
batteries and a potential method for allowing the batteries to last longer. It also provides
insight and guidance for potential future research of stabilization of lithium-ion materials. === Master of Science === Consumers across the world use lithium-ion batteries in some fashion in their everyday life.
