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. |

The invention relates to a microporous and mesoporous carbon xerogel and organic precursors thereof based on a phenol-formaldehyde xerogel. A characteristic parameter common to carbon xerogels is a peak in the mesopore size distribution determined by the BJH method (Barrett-Joyner-Halenda) from nitrogen absorption measurements at 77 K in the range from 3.5 nm to 4 nm. The production process is characterized firstly by the low starting material costs (use of phenol instead of resorcinol) and secondly by very simple and cost-effective processing; convective drying without solvent exchange instead of supercritical drying or freeze drying. The carbon xerogels and their organic phenol-formaldehyde xerogel precursors have densities of corresponding to a porosity of up to 89%, and the xerogels can also have a relevant mesopore volume. The carbon xerogels obtained from the phenol-formaldehyde xerogels are also microporous. |
