Mesoporous Ti4O7 Nanosheets with High Polar Surface Area for Catalyzing Separator to Reduce the Shuttle Effect of Soluble Polysulfides in Lithium‐sulfur Batteries
In the effort to accelerate adsorption and catalytic conversion of lithium polysulfides (Li‐PSs) and suppress the shuttle effect of lithium‐sulfur batteries (LSBs), the Ti4O7 nanosheets/carbon material‐modified separator is successfully fabricated to reducing soluble Li‐PSs’ crossover from cathode t...

description | In the effort to accelerate adsorption and catalytic conversion of lithium polysulfides (Li‐PSs) and suppress the shuttle effect of lithium‐sulfur batteries (LSBs), the Ti4O7 nanosheets/carbon material‐modified separator is successfully fabricated to reducing soluble Li‐PSs’ crossover from cathode to anode. The catalyst of mesoporous Ti4O7 nanosheets with O−Ti−O units synthesized at low temperature shows both excellent conductivity and high surface area. The modified separator can serve as a diffusion barrier of Li‐PSs and catalyst for converting soluble low‐chain sulfides into insoluble ones and then remarkably enhance the sulfur utilization and electrochemical performance of the LSB. This work provides a feasible avenue in both design and synthesis of mesoporous catalyst materials for suppressing the shuttle effect of lithium‐sulfur batteries.
The catalyst of M−Ti4O7‐6 NS with O−Ti−O units shows both excellent conductivity and high surface area, which is beneficial to effectively accelerate adsorption and catalytic conversion of Li‐PSs and largely suppress the shuttle effect of LSBs. When this M−Ti4O7‐6 NS are used for the catalyst coated on the separator, the modified separator with CB/M−Ti4O7‐6 NS catalyst layer can serve as a diffusion barrier of Li‐PSs and significantly enhance electrochemical performance of LSBs. |
