Improving Na-beta”-alumina interface and grain boundary as solid-state electrolyte for large scale Room Temperature applications: Effect of particle size and liquid addition on capacity, conductivity and cyclability

The aim of my project at the Storage of Electrochemical Energy section of the TU Delft is to improve the performance and uncover the electrolytic hurdles of the widely used Na-beta”-alumina solid electrolyte within Sodium semi solid-state batteries at Room Temperature. Na-beta”-alumina could be an interesting candidate to replace volatile and...

Effects of Redox-mediator Electrolyte on the Electrochemical Performance of a Nonaqueous Li-O2 battery

Organic crystals and improved electrolyte for aqueous sodium-ion batteries: Fundamental insights in new organic anode materials for aqueous sodium-ion batteries using DFT calculations and experimental insights in increased electrolyte stability

Density Functional Theory (DFT) calculations were performed to explore the electrochemical properties of two organic molecules that show promise to serve as affordable and safe anode materials in aqueous sodium-ion batteries. Upon sodium insertion, N,N’ –bis(methyl)- 1,4,5,8-naphthalene diimide (NDMe) appears to share sodium atoms with three...

Simulation of lithium distribution and diffusion pathways in Li₆PS₅X (X = Cl, Br, I) and Li₇PX₆ (X = S, Se) by means of ab-initio molecular dynamics

Diffusivities and lithium distributions in Li₆PS₅X (X = Cl, Br, I) and Li₇PX₆ (X = S, Se) are investigated by means of molecular dynamics simulations. The best lithium conduction is found in Li₆PS₅Cl with diffusivity of over 1 S/cm at 600 K. The halide rich Li₅PS<sub>4<...
