Rosalind Gummow’s work has focussed on the fundamental understanding of the relationship between crystallographic structure and electrochemical properties of lithium transition metal oxides.  This understanding underpins the intelligent design and optimization of energy materials, with practical application in devices like lithium-ion batteries.  She has been involved in the development of lithium transition metal oxides for application as lithium-ion battery cathodes since the early 1990’s when rechargeable lithium-ion battery technology was first established.  Examples of her work include: the first reported preparation of a quasi-spinel LT-LiCoO2, stabilization of the LiMn2O4 spinel framework by partial substitution of Mn cations with Li,Mn,Zn or Al, and the development of the Li4Ti5O12/Li1+xMn2-xO4 electrode couple while working with Argonne National Laboratory Distinguished Fellow Dr Michael Thackeray at the CSIR in South Africa. This work has resulted in 13 patents, several of which have been commercialized internationally.  The stabilized spinel compounds form a significant part of the batteries that were used in first generation Chevy Volt and Nissan Leaf vehicles.
