Effect of Carbon and Binder on High Sulfur Loading Electrode for Li-S Battery Technology
Ke Sun,Christina A. Cama,Jian Huang,Qing Zhang,Sooyeon Hwang,Dong Su,Amy C. Marschilok,Kenneth J. Takeuchi,Esther S. Takeuchi,Esther S. Takeuchi,Hong Gan +10 more
TL;DR: In this article, the impact of binder and carbon type on the mechanical integrity and the electrochemical properties of sulfur electrodes was evaluated at relatively high sulfur loading, and the authors identified hydroxypropyl cellulose (HPC) as a new binder for the sulfur electrode because it offers better adhesion between the electrode and the current collector than the commonly used polyvinylidene fluoride (PVDF) binder.
