The potential application of exfoliated MoS2 to aqueous lithium-ion batteries

چکیده
Cost-effective storage remains one of the greatest challenges facing adoption renewable energy generation. Herein we present a cost-effective aqueous rechargeable battery based on MoS2. Increased discharge capacities are achieved by liquid-phase exfoliation, resulting in 105% increase capacity and prolonged lithiation plateau. Contributing evidence is provided High Resolution TEM investigation expanded van der Waals gap between adjacent MoS2 layers particle active surface area. Exfoliated MoS2/graphite composite cathode also investigated, an reversible levels over 3x that base exfoliated material. The preservation voltages indicates highly effective improving lithiation. Further examination cost-effectiveness reveals vastly superior storage-to-cost ratios relative to other ARB cathodes.

Lithium (Li)-ion batteries (LIB) have governed the current worldwide rechargeable battery market due to their outstanding energy and power capability. In particular, the LIB’s role in enabling electric vehicles (EVs) has been highlighted to replace the current oil-driven vehicles in order to reduce the usage of oil resources and generation of CO 2 gases. Unlike Li, sodium is one of the more abu...

DOI: 10.1002/aenm.201600922 considering the overpotential during charge process. Recently, Yamada et al. reported that LiNi0.5Mn1.5O4 can only reversibly provide capacity of ≈75 mA h g−1 in the more concentrated hydrate melt electrolytes (≈30 mol kg−1), which is 50% of theoretical capacity.[14] The oxygen evolution side reaction also largely significantly reduce the coulombic efficiency. In add...

In this article, alkali lignin (AL)-assisted direct exfoliation of MoS2 mineral into single-layer and few-layer nanosheets in water is reported for the first time. Under optimized conditions, the concentration of MoS2 nanosheets in the obtained dispersion can be as high as 1.75 ± 0.08 mg mL(-1), which is much higher than the typical reported concentrations (<1.0 mg mL(-1)) using synthetic polym...
