End of Life Studies of Coated Cathode Materials for Lithium Ion Batteries

Electric vehicles have been adopted around the world as an alternative to combustion engine vehicles. It has been a focus for academic and industry research efforts to develop battery materials with reduced cobalt, but the removal of cobalt comes at a cost. Reduced cobalt often decreases the stability of these materials. Further improvements to the power and stability of materials with reduced amounts or no cobalt will require establishing scalable methods for incorporating custom coatings.

Characterization of Stabilized Lithium Ion Battery Materials

Micro-scale particles composed of high-voltage spinel LNMO (LiNi1-xMnxO4) will be characterized using electron microscopy techniques. These particles are stabilized through the inclusion of coating materials. The methods to prepare these particle coatings consisted of either an in-situ or post-synthetic method. The interface between the particle and the coating will be characterized at the atomic-scale by high-resolution transmission electron microscopy (HR-TEM).

Development of in operando characterization methods for lithium ion battery materials - Year two

The successful commercialization of new cathode materials for lithium ion batteries requires an improved and detailed understanding of the correlations between their structure, properties, and performance. Such a correlation will provide a foundation for better understanding the degradation mechanisms and optimized operating conditions for these cathode materials; pairing new battery materials with ideal applications and standardizing the methods by which these materials are evaluated.
