WebAll-solid-state lithium–sulfur batteries (ASSLSBs) have high reversible characteristics owing to the high redox potential, high theoretical capacity, high electronic conductivity, and low Li + diffusion energy barrier in the cathode. Monte Carlo simulations with cluster expansion, based on the first-principles high-throughput calculations, predicted a phase structure … WebArtemis 0.9.26 documentation ». 13. Worked examples ». 13.1. Example 1: FeS2 ¶. Iron pyrite, FeS 2, is my favorite teaching example which I use to introduce people to fitting with ARTEMIS. It is a crystal with a well-known structure. I have beautiful data. And I am able to create a very successful fitting model.
