Název v původním jazyce

Synthesis of Sulphur-Carbon Nanotubes Composite via Carbon Disulphide Solution for Li-S Batteries

Popis výsledku v původním jazyce

Demant for high energy density batteries are increasing and current used lithium-ion batteries do not meet the requirements for high energy density and specific capacity. Lithium-sulphur batteries may replace lithium-ion batteries in their applications, such as personal portable devices, electromobility or stationary energy storage systems due to high theoretical capacity. Though, lithium-sulphur batteries have some major drawbacks, that block commercialization. Porous, conductive materials and optimization of electrode material preparation can suppress shortcoming of lithium-sulphur batteries. Metal-organic framework in combination with carbon Super P and multiwall carbon nanotubes can effectively confine and capture sulphur. The initial discharge capacity of the S/MOF-76(Gd)/C-CS2 electrode is 735 mAh g-1 with capacity retention of 107 % after 50 cycles.
