Speciation of aluminium in mixtures of the ionic liquids [C 3mpip] [NTf2] and [C4mpyr] [NTf2] with AlCl3: An electrochemical and nmr spectroscopy study

This paper reports on the electrodeposition of aluminium on sev-eral substrates from the air- and water-stable ionic liquids 1-propyl-l-methyl- piperidinium bis(trifluoromethylsulfo-nyl)amide ([C3mpip][NTf 2]) and 1-butyl-1-methylpyrrolidinium bis(tri-fluoromethylsulfonyl) amide ([C4mpyr]-[NTf2]), which contain anhydrous AlCl 3. At an AlCl3 concentration of 0.75 molal, no evidence for aluminium electrodeposition was observed in either system at room temperature. However, aluminium electrodeposition becomes feasible upon heating the samples to 80°C. Aluminium electrode-position from bis(trifluoromethylsulfo-nyl)amide-based ionic liquids that con-tain AlCl 3 has previously been shown to be very dependent upon the AlCl 3 concentration and has not been dem-onstrated at AlCl3 concentrations below 1.13 molal. The dissolution of AlCl3 in [C 3mpip][NTf2] and [C4mpyr]-[NTf2] was studied by variable-temper-ature 27Al NMR spectroscopy to gain insights on the electroactive species re-sponsible for aluminium electrodeposi-tion. A similar change in the aluminium speciation with temperature was observed in both ionic liquids, thereby indicating that the chemistry was simi-lar in both. The electrodeposition of aluminium was shown to coincide with the formation of an asymmetric four-coordinate aluminium-containing spe-cies with an 27Al chemical shift of δ = 94 and 92 ppm in the [C3mpip] [NTf2]-AlCl3 and [C4mpyr] [NTf2]-AlCl3 sys-tems, respectively. It was concluded that the aluminium-containing species that give rise to these resonances corre-sponds to the electroactive species and was assigned to [AlCl3(NTf2)]-.

A Cation-Tethered Flowable Polymeric Interface for Enabling Stable Deposition of Metallic Lithium

A fundamental challenge, shared across many energy storage devices, is the complexity of electrochemistry at the electrode-electrolyte interfaces that impacts the Coulombic efficiency, operational rate capability, and lifetime. Specifically, in energy-dense lithium metal batteries, the charging/discharging process results in structural heterogeneities of the metal anode, leading to battery failure by short-circuit and capacity fade. In this work, we take advantage of organic cations with lower reduction potential than lithium to build an electrically responsive polymer interface that not only adapts to morphological perturbations during electrodeposition and stripping but also modulates the lithium ion migration pathways to eliminate surface roughening. We find that this concept can enable prolonging the long-term cycling of a high-voltage lithium metal battery by at least twofold compared to bare lithium metal.
