Layered Oxide Phases for Sodium-ion Battery Electrodes
MetadataShow full item record
Sodium-ion batteries could offer an economical and environmentally friendly alternative to lithium-ion batteries, however many challenges must be overcome first. This project focused on the investigation of layered sodium transition metal oxide phase systems. These systems are of great importance for the development of not only cathode materials but anode materials as well for sodium-ion batteries. The high energy densities and ease of sodium intercalation of these layered systems make them prime candidates for implementation in sodium-ion batteries. It is desirable that simple, low cost synthesis methods be used to obtain these materials. The work herein aimed at understanding the synthesis and electrochemistry of the Na-Ni-Mn-O and Na-Ni-Ti-O phase systems, as well as other select phases that allow for facile sodium-ion diffusion.
