Stabalzing Mesh Could Bring Lithium-Sulfur Batteries to Market

Stabalzing Mesh Could Bring Lithium-Sulfur Batteries to Market

A novel stabilizing nanomesh fiber mat has eliminated one of the obstacles of bringing lithium-sulfur batteries to commercialization.

Though lithium-sulfur batteries show great promise with their superior energy storage capabilities, their application has been limited because sulfur tends to migrate from the electrode as polysulfides, degrading the battery’s performance after only a few cycles.

To help bring this promising battery technology forward, the team from the Drexel College of Engineering created a freestanding, highly-conductive porous titanium monoxide nanofiber mat that will trap polysulfides created while the battery is being used. This prevents the polysulfides from dissolving in the battery electrolytes and preserves performance, with a reported sustained effective capacity four times higher than standard lithium-ion batteries.
