  • Highly-efficient conversion of SF6 via an eight

    2020-4-2potential owing to the sufficient sites for mass transfer and charge transfer. Our experimental and DFT results, however, reveal that SF6 is insufficient to be reduced to Li2S under this atmosphere. LiF on the gas electrode and solvated polysulfides in the electrolyte are the predomi-nant reduced species.

  • Highly-efficient conversion of SF6 via an eight-electron

    2020-6-1Each cell included a lithium metal anode (16 mm in diameter), two pieces of Celgard separators (19 mm in diameter) soaked with 50 μL of electrolyte and a carbon electrode. The cathode shell was drilled a hole (3 mm in diameter) prior to use. Then the assembled cells were placed in a glass bottle filled with SF 6. TheCited by: 2
