The Application of Isothermal Microcalorimetry to the Study of Parasitic Reactions in Lithium Ion Batteries
In an ongoing effort to advance the understanding of how electrolyte composition impacts the performance and lifetime of lithium ion cells, this work introduces the use of isothermal microcalorimetry as a tool to measure ... -
CHANGES TO THE ELECTROLYTE IN AGED LI-ION CELLS
Electrolyte composition is crucial to the lifetime, cycling capability and safety of Li-ion cells. Many studies have measured electrolyte changes after formation or during the first few charge and discharge cycles, while ... -
Development of A New Cell Design for Battery Research and an Investigation of Electrode Materials and Electrolyte Systems For Mg Batteries
(2014-12-10)Magnesium batteries are considered as an inexpensive and high energy density alternative to Li-ion batteries. One of these challenges in Mg batteries is the lack of rigid, inexpensive cell hardware to test new electrode ... -
STUDY AND DEVELOPMENT OF LAYERED LI-NI-MN-CO OXIDE POSITIVE ELECTRODE MATERIALS FOR LITHIUM ION BATTERIES
Layered Li-Ni-Mn-Co oxides (NMC) with low cobalt content are promising positive electrode materials for Li-ion batteries. However, the detailed structural properties of these materials are still debated. This thesis work, ... -
STUDY OF THE REACTIVITY OF ELECTROLYTE SOLVENTS AND ADDITIVES IN LI-ION CELLS AND DESIGN OF NEW ELECTROLYTE BLENDS
While electrolyte additives have a great impact on Li-ion cell lifetime, the ways they work are still poorly understood. In an effort to better understand how additives function, two gas chromatography-based methods were ... -
STUDYING LONG TERM LI-ION ELECTROLYTE DEGREDATION USING LITHIUM ION DIFFERENTIAL THERMAL ANALYSIS
Lithium ion cells contain liquid electrolytes that degrade over the lifetime of the cell. Though the results of this degradation are well understood, the pathways are not. Lithium ion differential thermal analysis (Li-ion ... -
The Use of Alloy Anodes and Conventional Electrolytes in Magnesium Batteries
(2015-04-16)Magnesium-based batteries are promising for use in future electrified vehicles and electrical power grids due to their high theoretical volumetric energy. However, there exist many challenges in the development of electrode ...
