Lithium Borate Glass Ceramics and Multi-Walled Carbon Nanotube Composite as Efficient Sulfur Hosts for Enhanced Lithium-Sulfur Batteries
The transformation of sulfur molecules over a glass-carbon nanotube cathode was validated using X-ray absorption spectroscopy. The XANES results highlighted the performance of lithium borate glass for lithium-sulfur batteries. LBO promoted sulfur diffusion and inhibited electrochemical reduction of lithium polysulfide on the lithium anode surface.
