A Ni-MOF derived graphene oxide combined Ni3S2–Ni/C composite and its use in the separator coating for lithium sulfur batteries

Abstract: lithium-sulfur batteries (LSBs) are widely regarded as a reliable novel secondary battery due to its popular price and high capacity. Nevertheless, the notorious "shuttle effect" limits the commercialization of LSBs....

“…The t Li + was calculated based on the Bruce–Vincent formula as below. 39 t Li + = I S ( V − I 0 R 0 )/ I 0 ( V − I S R s )where V refers to the polarization voltage (10 mV), and R 0 and R S stand for bulk resistances of cells before and after the potentiostatic polarization. The PPK-modified separator has a similar t Li + value (0.813) compared with the PE separator (0.828), reflecting that the modified layer hardly influences the transfer ratio of lithium ions in the electrolyte solution.…”

“…Figure 3(b) depicts the pore structures of BP2000 and Fe 2 O 3 /BP2000 composite, both of the two materials are composed of pores form 2-10 nm, and most of the pore diameter are around 3.8 nm, the pore volumes of BP2000 and Fe 2 O 3 /BP2000 composite are 2.8 and 2.54 m 3 g − 1 , the decrease of pore volume also demonstrates that Fe 2 O 3 particles are con ned by the pores of BP2000. Additionally, the relatively small pore diameter can effectively absorb the soluble lithium polysul des [22][23].…”

“…[12] Metal active sites can enhance the absorption ability based on its polar nature, moreover these active sites have excellent catalytic effect on the conversion of lithium polysulfides which can obviously improve the discharge capacity and cycle stability of LiÀ S battery. [13,14] MnO 2 , TiO 2 , CeO 2 etc. are all demonstrated as excellent sulfur host.…”
