Implementation of Bismuth Chalcogenides as an Efficient Anode: A Journey from Conventional Liquid Electrolyte to an All-Solid-State Li-Ion Battery

“…Several reports stated that the cyclic stability of Bi-based electrodes remained less than 300 mAhg −1 after 100 cycles [55][56][57][58]. These lower capacity and cyclic stability issues were solved by the implementation of Bi anode in all-solid-state Li-ion batteries [59]. Jain and co-workers did excellent work in this regard.…”

“…Details of all-solid-state Li-ion batteries (ASSLIBs) are already discussed in the introduction section. They These lower capacity and cyclic stability issues were solved by the implementation of Bi anode in all-solid-state Li-ion batteries [59]. Jain and co-workers did excellent work in this regard.…”

“…Some similar effects were also observed in Bi 2 Se 3 and Bi 2 Te 3 nanostructure composite anode materials. Bi 2 Se 3 nanostructures in a mixed morphology, i.e., nanoparticles and nanosheets, were prepared by the hydrothermal method [59]. These prepared nanostructures showed a first discharge capacity as 594 mAhg −1 , which was faded down to 343 mAhg −1 in the 50th cycle.…”

Flower-like Bi2S3 nanostructures as highly efficient anodes for all-solid-state lithium-ion batteries

“…8 A similar cushioning effect was also observed in our recent report where a hydride based solid electrolyte -LiBH 4 was used with Bi (as an anode) to assemble an all-solid-state battery and the obtained results showed that the existence of LiBH 4 as well as acetylene black (AB) impressively improved the cyclability of Bi anode. 9 In order to further enhance the capacity, Bi based chalcogenides (Bi 2 X 3 ; X ¼ S, Se, Te) have been explored, as the element X has ability to alloy with Li. 10,11 Out of these chalcogenides, Bi 2 S 3 possesses highest capacity and in addition to Li-ion batteries it has been widely used in many elds, such as optics, 12,13 photoelectricity, 14,15 photocatalysis 16,17 and biology 18,19 due to its direct band gap (1.3 eV).…”
