Cr-Ga-N materials for negative electrodes in Li rechargeable batteries : structure, synthesis and electrochemical performance

Electrochemical performances of two ternary compounds (Cr2GaN and Cr3GaN) in the Cr-Ga-N system as possible future anode materials for lithium rechargeable batteries were studied. Motivation for this study was dealt in chapter 2 following chapter 1 that covered introduction to batteries, lithium ion batteries and anode materials for lithium ion batteries. Synthesis method with less time was attempted and factors affecting synthesis of these compounds were investigated. (Chapter 3) Through electrochemical characterization and insitu XRD, practical values of electrochemical capacities were examined in comparison with theoretical capacity values (Chapter 4) and also possible reaction mechanisms of these compounds vs. Li were proposed (Chapter 5).
