As part of the School of Science and Technology Chemistry and Forensic Science Colloquium Pooja Goddard, Loughborough University presents: Modelling of Solid State Electrolyte materials for Li Battery Applications.

Abstract

Solid state lithium ion batteries are gaining considerable momentum due to the need for an efficient, high energy, high power form of energy storage systems. Therefore, research interests in solid electrolytes has amplified in recent years. The high chemical, electrical and mechanical stability possessed by these materials make them ideal candidates for storage systems operating over wide voltage and temperature ranges.

In this talk I will discuss 2 example materials. The first being lithium-stuffed garnet, Li7La3Zr2O12, known as LLZO. It is one of the most promising materials when suitably doped within this category and has attracted a great deal of attention – leading to a detailed understanding of its structure and potential lithium ion migration mechanisms, particularly with cation doping e.g. Al, Ta etc.. In contrast, there is a lack of studies of anion doping in this material, and indeed such investigations are also lacking in other battery materials.

The second being the Lithium phosphidosilicate material class of materials, which has a complex tetrahedral framework and therefore large unit cells that are not trivial to model. In this work we explore three dopants, Al, Ga and B with a view to investigate the defect chemistry, ion migration mechanisms and voltage.
