Stabilization of Li–S batteries with a lean electrolyte via ion-exchange trapping of lithium polysulfides using a cationic, polybenzimidazolium binder
Autor: Simon Thiele, Lili Liu, Steven Holdcroft, Chuyen Van Pham, Michael Walter, Benjamin Britton
Publikováno v: Sustainable energy & fuels 4(3), 1180-1190 (2020). doi:10.1039/C9SE01092K
Implementing Li-S cells using high S loading and lean electrolyte content is considered the only viable way to achieve competitive specific energy for practical applications. However, under these conditions, the cell cycle life and performance are dr

Improved Hole Injection in Bulk Heterojunction (BHJ) Hybrid Solar Cells by Applying a Thermally Reduced Graphene Oxide Buffer Layer
Autor: Chuyen Van Pham, Alfian F. Madsuha, Michael J. Eck, Michael Krueger, Martin Neukom
Publikováno v: Journal of Nanomaterials, Vol 2019 (2019)
In this work, the utilization of graphene oxide (GO), reduced graphene oxide (rGO), and carbon nanotube (CNT) thin films as hole transport and electron-blocking layers in polymer/nanocrystal hybrid solar cells is demonstrated. A simple method has bee
