Invited review on “Computational Studies of Alkali Diffusion”

Our group has recently been invited to write a comprehensive review on computational studies of solid-state alkali conductivity in rechargeable alkali-ion batteries. This article has now been published in NPG Asia Materials! Check it out at http://www.nature.com/doifinder/10.1038/am.2016.7.

Insights into the Li7P3S11 superionic conductor

Iek-Heng Chu just published a new article in ACS Applied Materials & Interfaces. This is a highly collaborative work involving the expertise of many MAVRL group members as well as the Meng group. In this work, we investigate the performance limits of Li7P3S11, a highly promising lithium superionic conductor solid electrolyte. We find that Li7P3S11…
