Lithium-Rich Transition Metal Oxides as Positive Electrode Materials in Lithium-Ion Batteries
(2010-11-19)Lithium-rich transition metal oxides are candidates for the next-generation lithium-ion battery positive electrode materials. They have a much higher first charge and low-rate cycling capacity compared to non-lithium rich ... -
Structure, Magnetic Ordering and Electrochemistry of Li1+xV1-xO2
(2011-04-08)The layered transition metal oxide composition series of Li1+xV1-xO2 was synthesized using the solid state synthesis technique. X-ray diffraction was used to determine the dependence of structure on composition and clearly ... -
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, ... -
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 ... -
SURPRISING CHEMISTRY IN LI-ION CELLS
High voltage LiNixMnyCo(1-x-y)O2 (NMC) cells with conventional ethylene carbonate-based electrolytes do not have good charge-discharge capacity retention above 4.3 V. It is therefore important to investigate the failure ... -
Synthesis and Characterization of Magnesium and Manganese Doped LiCoO2
LiCo1-2xMgxMnxO2 (0 ≤ x ≤ 0.05) positive electrode materials were prepared from Co1-2xMgxMnx(OH)2 (0 ≤ x ≤ 0.05) co-precipitated precursor materials by mixing precursor materials with Li2CO3 and heating. All precursor and ...
