  1. Sulfur-Based Yolk-Shell Nanoparticles for Lithium Sulfur Batteries

    Liu, Tingting 1988-University of Houston2018

    … focuses on the synthesis of gold-functionalized sulfur yolk-shell nanoparticles. Sulfur was chosen as a cathode material due to its high theoretical specific capacity (1675 mA h g−1). However, there are still many technical limitations for Li-S batteries, like the dissolution of the intermediate …
