Patent number: 9225011Abstract: We report a heteroatom-doped carbon framework that acts both as conductive network and polysulfide immobilizer for lithium-sulfur cathodes. The doped carbon forms chemical bonding with elemental sulfur and/or sulfur compound. This can significantly inhibit the diffusion of lithium polysulfides in the electrolyte, leading to high capacity retention and high coulombic efficiency.Type: GrantFiled: July 10, 2013Date of Patent: December 29, 2015Assignee: THE PENN STATE RESEARCH FOUNDATIONInventors: Donghai Wang, Tianren Xu, Jiangxuan Song

Publication number: 20120207994Abstract: Embodiments presented herein provide a new approach for high-performance lithium-sulfur battery by using novel carbon-metal oxide-sulfur composites. The composites may be prepared by encapsulating sulfur particles in bifunctional carbon-supported metal oxide or other porous carbon-metal oxide composites. In this way, the porous carbon-metal oxide composite confines sulfur particles within its tunnels and maintain the electrical contact during cycling. Furthermore, the uniformly embedded metal oxides in the structure strongly adsorb polysulfide intermediates, avoid dissolution loss of sulfur, and ensure high coulombic efficiency as well as a long cycle life.Type: ApplicationFiled: February 13, 2012Publication date: August 16, 2012Inventors: Donghai Wang, Zhongxue Chen, Tianren Xu
