Abstract:

Based on the unique ubiquity of similar solvate structures found in solvate crystals and superconcentrated electrolytes, we performed a systematic study of four reported solvate crystals which consist of different lithium salts (i.e., LiMPSA, LiTFSI, LiDFOB, and LiBOB) solvated by acetonitrile (MeCN) based on first principles calculations. Based on the calculations, these solvate crystals are predicted to be electronic insulators and are expected to be similar to their insulating liquid counterpart (e.g., 4 M superconcentrated LiTFSI-MeCN electrolyte), which has been confirmed to be a promising electrolyte in lithium batteries. Although the MeCN molecule is highly unstable during the reduction process, it is found that the salt-MeCN solvate molecules (e.g., LiTFSI-(MeCN)2, LiDFOB-(MeCN)2) and their charged counterparts (anions and cations) are both thermodynamically and electrochemically stable, which can be confirmed by Raman vibrational modes through the unique characteristic variation in C≡N bond stretching of MeCN molecules. Therefore, in addition to the development of new solvents or lithium salts, we suggest it is possible to utilize the formation of superconcentrated electrolytes with improved electrochemical stability based on existing known compounds to facilitate the development of novel electrolyte design in advanced lithium batteries.

Abstract:

We here report a superconcentrated potassium acetate (KAC) solution (75[Formula: see text]wt.%, K : H2O [Formula: see text] 1 : 1.8, called as “water-in-salt”) as an aqueous electrolyte to improve the working voltage and increasing capacitance in enhancing the energy density of the active carbon-based aqueous supercapacitor. The stability potential window of the superconcentrated electrolyte realizes an AC//AC symmetric supercapacitor with operating voltage of 2.0 V and excellent cyclic performance. Meanwhile, the energy density of such supercapacitor achieves about twice as high as that of the supercapacitor using normal concentration of electrolyte.

Abstract:

Leveraging the most recent success in expanding the electrochemical stability window of aqueous electrolytes, in this work we create a unique Li-ion/sulfur chemistry of both high energy density and safety. We show that in the superconcentrated aqueous electrolyte, lithiation of sulfur experiences phase change from a high-order polysulfide to low-order polysulfides through solid–liquid two-phase reaction pathway, where the liquid polysulfide phase in the sulfide electrode is thermodynamically phase-separated from the superconcentrated aqueous electrolyte. The sulfur with solid–liquid two-phase exhibits a reversible capacity of 1,327 mAh/(g of S), along with fast reaction kinetics and negligible polysulfide dissolution. By coupling a sulfur anode with different Li-ion cathode materials, the aqueous Li-ion/sulfur full cell delivers record-high energy densities up to 200 Wh/(kg of total electrode mass) for >1,000 cycles at ∼100% coulombic efficiency. These performances already approach that of commercial lithium-ion batteries (LIBs) using a nonaqueous electrolyte, along with intrinsic safety not possessed by the latter. The excellent performance of this aqueous battery chemistry significantly promotes the practical possibility of aqueous LIBs in large-format applications.

Abstract:

Accurate analysis of the mechanism of interphase formation and its composition is imperative for the development of stable and efficient lithium/sodium-ion batteries. One of the most practically scalable ways to optimize interphase chemistry and morphology for reversible charge transport is electrolyte engineering and the application of formation protocol with specific current/voltage conditions. In this sense, the analysis of structure and dynamics within the electrode/electrolyte interface, i.e., the so-called electric-double layer, is essential to predicting the possible chemistry and mechanism of interphase formation. The latest was recently advanced by understanding the effect of electrolyte chemistry, e.g., the chemical structure of solvent and salt, their ratio, the presence of additives etc.1–4 Although, the role of electrode material is often neglected which creates an impression that both metallic and semiconductive electrodes form an identical electric-double layer within the same electrolyte, therefore, the mechanism of interphase formation should be very similar regardless of the chemical nature of the electrode. Here, we used examples of sodium-salt-containing ionic liquids and carbonate electrolytes to demonstrate that structural changes at the electrified interface are greatly affected by the dielectric nature of electrode material. The key observation is attributed to the different abilities of electrified electrodes to form van der Waals interactions with the electrolyte species. This affects the concentration of metal-anion complexes in relation to organic solvent near the electrode, therefore, different interphase chemistry will be formed (inorganic-rich vs. organic-rich), and different formation protocols must be used. For example, Fig. 1 shows the summary of this phenomenon for ionic liquid electrolytes with 50 mol% sodium bis(fluorosulfonyl)imide. Besides, metallic and semiconductive electrodes demonstrated different affinity toward polar organic solvent, i.e., ethylene carbonate, in 1.0 M NaPF6 in EC:DMC (1:1 by volume) electrolyte. This presentation will discuss the details of these fundings and introduce future applications.

Abstract:

Electrode/electrolyte interface is an important part of many electrochemical systems, as its local structure, so called electric double layer (EDL), defines mechanism of charge transfer and stability of the device. Alkaline metal anodes possess high theoretical capacity due to ability of metal-ions to pack in the dense crystal structure, however, their application is rather limited due to formation of dendrites from non-uniform metal deposition and/or poor quality of the interphase. Experimentally, it was found that variation of ionic liquid (IL) electrolyte composition (salt concentration, presence of cosolvent) and applied current density for the formation cycling, i.e., cycling to activate electrode surface before utilisation, significantly affect dendritic growth and stability of metal anode. This presentation aims to show the molecular level relationships between interfacial structure, value of metal deposition potential and the interphase formation with ionic liquid electrolyte of different compositions (salt concentration, presence of cosolvent). Each electrolyte composition results in a particular interfacial metal-ion solvation environment which controls the reductive stability, metal-ion deposition potential, and ultimately the composition and properties the solid-electrolyte interphase (SEI). The latter is dependent on the EDL composition such as the IL cation/metal cation-IL anion ratio or the presence of other surface active additives. Based on this work, our group at Deakin University developed a theoretical framework to choose an optimum current density for the formation cycling of lithium/sodium metal anodes with ionic liquid electrolytes of different composition (salt concentration, presence of cosolvent).

Abstract:

Solid-electrolyte interphases (SEI) are essential to the stability of high voltage lithium-ion batteries (LIBs) where they act as a protective barrier that prevents electrolyte decomposition during charge-discharge and during storage of the energy. Within emerging water-in-salt electrolytes (WISE), the SEI are thought to play a similar role in preventing electrolyte decomposition and expanding the potential window.(1, 2) The SEI reported in WISE are derived from the electrolyte ions, producing inorganic SEI (e.g. LiF) of similar thickness to non-aqueous batteries.(1) Others suggest the superconcentrated regimes promote anion reduction and shift its reduction potential at similar or more positive potentials to hydrogen evolution. However, our knowledge on the SEI found in concentrated aqueous electrolytes and their properties remains quite limited. Furthermore, WISE full cells can access >1000 cycles at high rates, but their capacities and retention are still heavily lacking compared with commercial LIBs.(2) Improving our understanding of the WISE-based SEI formation process, its stabilization, and prevention of gas evolution are key to achieving higher performing aqueous batteries. Herein, we explore the use of advanced scanning electrochemical microscopy (SECM) methods(3) to characterize an SEI within a highly concentrated K(FSA)0.6(OTf)0.4 electrolyte. Focusing on a 3,4,9,10-perylenetetracarboxylic diimide (PTCDI) composite electrode, we use both ex situ, approach curves as well as in situ single spot measurements to analyze SEI formation (Figure 1a). The approach curves were collected before and after galvanostatic cycling by using a three-electrode cell that could easily be converted between closed (cycling) and open-cell (SECM) measurements. After cycling, we observed passivating SEI structures with electron transfer rates comparable to those found in LIBs (Figure 1b). At the same time, our results indicated the SEI deposition was discontinuous with some regions showing reactivity comparable to an uncycled electrode. We noted an increase in roughness with cycling, which could produce some of the more reactive regions exposed at the electrode surface. Thereafter, we conducted in situ measurements at a constant distance from the PTCDI surface.(4) During the first cycle, we observed a reversible/transient decrease in the feedback current at ~ -0.7 V vs. Ag/AgCl, far positive to H2 evolution (Figure 1c,d). In addition, more stable passivation was observed when the PTCDI electrode reached more negative potentials accessing the second redox process of PTCDI (Figure 1c,e). As the electrode reached potentials more negative to -1.3 V, we observed significant hydrogen evolution. Our results were further confirmed with operando electrochemical mass spectrometry (OEMS). OEMS showed similar potentials for evolving hydrogen as well as the evolution of other gases indicative of SEI formation. In all, our interfacial SECM analyses combined with traditional battery measurements and OEMS provides direct quantification of the passivating properties of the SEI as well as identification of local and bulk gas evolution that can be expanded for other emerging aqueous systems.

Abstract:

High voltage Li-ion batteries have been expected a forward technology designed for vehicles, marines and other high power and energy density applications 1–3. Among high voltage cathodes, LiNi0.5Mn1.5O4 is considered a promising cathode to reduce the battery cost as well as environmental hazard issues4,5. However, a high operation potential and Mn dissolution brings the most critical challenges for achieving the long cycle-life of Li-ion cell6,7. In this study, we report a rational design of nonflammable electrolyte based on LiBF4 and sulfolane (TMS) mixed with a dimethyl carbonate (DMC) as co-solvent to enhance conductivity. Among different molar ratios, the electrolyte LiBF4: TMS: DMC =1:2:1 in mol. exhibited the highest electrochemical stability (~ 6.1 V vs. Li+/Li) and ionic conductivity up to 1.57 mS.cm-1 at 30 oC. Cycling performance of LNMO/Li half-cell and LNMO/graphite full-cell cycled were carried out using the optimized electrolyte. While half-cells LNMO//Li display a high initial capacity of 118 mAh.g-1 and remain 56.48 % of initial value after 100 cycles, a full cell LNMO//Graphite with an areal loading of 1.0 mAh.cm-2 and low N/P ratio (~1.2) exhibited a better cycling stability than the one using commercial electrolyte 1M LiPF6/EC-DMC, 1:1 in vol (with initial capacity of 87 mAh.g-1 and capacity retention of 18% after 100 cycles8).
