Bi2Se3 Nanostructured Thin Films as Perspective Anodes for Aqueous Rechargeable Lithium-Ion Batteries

Abstract

In recent years, aqueous rechargeable lithium-ion batteries (ARLIBs) have attracted attention as an alternative technology for electrical storage. One of the perspective battery anode materials for application in ARLIBs is Bi2Se3, which has already shown good perspectives in the application of conventional lithium-ion batteries (LIBs) that use organic electrolytes. In this study, the electrochemical properties of Bi2Se3 thin films with two different layers on the electrode surface—the solid electrolyte interphase (SEI) and the Bi2O3 layer—were investigated. The results of this work show that the formation of the SEI layer on the surface of Bi2Se3 thin films ensures high diffusivity of Li+, high electrochemical stability, and high capacity up to 100 cycles, demonstrating the perspectives of Bi2Se3 as anode material for ARLIBs.

“…S7, ESI †). The radius of the medium-to-high frequency semi-circle, which stands for the charge transfer impedance (R ct ), 36 is increased during the charging process, corresponding to the Li + insertion process. 37 In Table S1 (ESI †), as we can see, the value of R ct keeps low at all states, which can explain the superior kinetic performance of the THP//LMO full battery.…”

“…It should also be noted that by changing the mass ratio of SWCNTs, the electrode capacity can be increased, and at an optimal concentration of Bi 2 Se 3 : SWCNT (1 : 1) the discharge capacity reaches 523 mAh g À 1 after 100 cycles. [36] The investigation of the electrode composed of bimetallic CuÀ Bi selenide@SWCNT (with relative content of SWCNT is 35 % by mass) revealed that its initial charge and discharge capacities are 520 mAh g À 1 (Figure 2c). These values are close to the analogous values for Cu 2 Se, although slightly lower.…”

“…[15,16] Bismuth selenide (Bi 2 Se 3 ) has attracted considerable attention due to its unique layered structure, high electrical conductivity, and excellent lithiumion diffusion kinetics. [17][18][19] However, like other chalcogenide materials, bismuth selenide faces the challenge of volume expansion during lithium-ion intercalation/deintercalation, which can lead to structural degradation and capacity loss during cycling. [20] The low-cost and environmentally friendly copper selenide (Cu 2 Se) is another interesting metal chalcogenide that has recently gained interest for applications in lithium-ion batteries.…”

“…40,41 The quintuple layer thickness is about 1 nm which 42 is sufficient to ensure full-fledged Li + intercalation/deintercalation processes, 41 making Bi 2 Se 3 a perspective candidate for the use as an anode for organic 39,43 and even aqueous LIBs. 44 However, major challenges, such as significant volume expansion during the Li + intercalation/deintercalation processes, capacity fading, and dissolution of selenium, have hindered practical application of Bi 2 Se 3 as anode material. 39,43,45 Recently, it has been demonstrated that Bi 2 Se 3 nanostructures can be synthesized directly on top of CNT networks.…”
