Atomistic analysis of Li migration in Li1+AlTi2?(PO4)3 (LATP) solid electrolytes

نویسندگان

چکیده

We examine the ionic migration of Li in LATP [$\text{Li}_{1+x} \text{Al}_x \text{Ti}_{2-x} {(\text{P} \text{O}_4)}_3$] solid electrolytes from an atomistic viewpoint by means density functional theory calculations. vary Al content and investigate its effects on crystal structure energy landscape interstitial ions. The profiles governing diffusion are found to be systematically influenced position ions direct vicinity path, we derive a simplified classification scheme three universal profile shapes. overall influence Al/Ti-ratio is analyzed separation into chemical geometrical aspects. This work provides basis for resource-efficient computational examination conductivity with varying Al/Ti concentrations.

Novel semi-solid electrolytes for Li-based batteries

Electrolytes of relevance for high performance batteries have to fulfill a variety of restrictive criteria: Not only is high Li conductivity a necessary condition to avoid too high losses, also an anion contribution as low as possible is desired as otherwise concentration polarization occurs [1]. Furthermore, the electrolyte should be mechanically stable. Beyond that, it should wet the electrod...

Li ion migration in Li3PO4 electrolytes: Effects of O vacancies and N substitutions

Motivated by recent developments in solid electrolytes based on lithium phosphorous oxynitride (LiPON) materials, we carried out computer simulations in order to develop an understanding of the detailed mechanisms of ionic transport. Starting with crystalline Li3PO4, we investigated some possible structures of isolated defects associated with extrinsic Li ion vacancies and interstitials. In par...

Nanometer-scale mapping of irreversible electrochemical nucleation processes on solid Li-ion electrolytes

Electrochemical processes associated with changes in structure, connectivity or composition typically proceed via new phase nucleation with subsequent growth of nuclei. Understanding and controlling reactions requires the elucidation and control of nucleation mechanisms. However, factors controlling nucleation kinetics, including the interplay between local mechanical conditions, microstructure...
