“…Further, lithium bis(oxalato)borate (LiBOB) is used as additive in various concentrations because of its well-known feature to prevent aluminum dissolution within narrow limits (Table II). 10,20 It should be noted that LiBOB is not fully dissolvable in solvent mixtures with high LiTFSA contents. For example it is shown in additional experiments that a mixture of 0.9 mol kg −1 LiTFSA + 0.1 mol kg −1 LiBOB is indissoluble in the DMMA-TFSA/PC mixture.…”

“…7,17 It is useful for preventing the anodic Al dissolution to add selected additives like lithium bis(oxalato)borate (LiBOB) ("corrosioninhibitors") in defined electrolyte mixtures. 10,20 In Figure 8, the results of the additive containing mixtures L-6, L-7, and L-8 are depicted in detail. All mixtures contain LiBOB as additive in various concentrations.…”

“…Unfortunately, anodic dissolution effects of aluminum are a well-known drawback in electrolyte mixtures based on lithium bis(trifluoromethanesulfonyl)azanide (LiTFSA; or: LiTFSI, lithium bis(trifluoro-methanesulfonyl)imide 1 ) and lithium triflate (LiOTf). [2][3][4][5][6][7][8][9][10][11][12] One result of different studies is the claim that aluminum dissolution at high potentials mostly depends on the conducting salt. 13 However, in the last few years, the solvent class of ionic liquids was investigated in more detail with respect to aluminum current collector corrosion as well.…”

A series of conducting salts in a liquid electrolyte mixture based on propylene carbonate and N,N-diethyl-N-methyl-N-(2methoxyethyl)ammonium bis(trifluoromethylsulfonyl)azanide is studied regarding anodic aluminum dissolution. In detail, the compatibility between the conducting salts LiBF 4 , LiOSO 2 CF 3 , LiClO 4 , LiPF 6 , and lithium bis(trifluoromethanesulfonyl)azanide and lithium ion grade aluminum foil is investigated. It is verified by electrochemical measurements, microscopy and XPS studies that in ionic liquid containing electrolytes the anodic aluminum dissolution strongly depends on the conducting salt. Furthermore it is shown that the aluminum dissolution can be suppressed effectively by the use of lithium bis(oxalato)borate (LiBOB). It is demonstrated that a minimal concentration of LiBOB is necessary depending on the conducting salt in the electrolyte to protect the aluminum surface reliably from anodic aluminum dissolution.

“…Aluminum is an essential component used as the positive current collector for Li-ion batteries [23][24][25][26][27][28][29][30]. However, aluminum could not be used as the negative current collector for Li-ion batteries owing to the alloying effect of aluminum with lithium [31,32].…”

The electrochemical behavior of magnesium deposition-dissolution on scratched aluminum foils in Grignard reagent/tetrahydrofuran (THF) solutions (1 mol L 1 EtMgBr/THF), which is regarded as a potential electrolyte of rechargeable magnesium batteries, was studied by using various methods such as cyclic voltammetry (CV), scanning electron microscopy (SEM), X-ray diffraction (XRD) and charge-discharge (deposition-dissolution) tests. The results present that the obtained magnesium deposits do not exhibit the morphology of dendrite and the Mg-Al alloy is not found on the surface of aluminum foils. The magnesium deposited on the aluminum substrates have excellent electrochemical cyclic performance in 1 mol L 1 EtMgBr/THF solution. The aluminum can be used as a candidate material of the negative current collector for rechargeable magnesium batteries. Electrochemical energy storage devices are key components for innovative power train systems such as plug-in hybrid vehicle (PHV), fuel cell hybrid vehicle (FCHV), and electric vehicle (EV) [1,2]. Currently, Li-ion batteries have been widely used in the fields of hybrid electric vehicles (HEV) and EV due to their high energy densities. However, there are some shortcomings which have not been resolved in Li-ion batteries, such as poor safety performance and high cost [3,4]. Magnesium as an electrode has the advantages of high Faradic capacity, environmental acceptability, good reliability, high safety and low cost. Therefore, the rechargeable magnesium battery is considered as an ideal substitution for the Li-ion battery in the future [5,6], which is becoming an attractive power battery and developed by many international companies and research institutes [7,8]. Liebenow [9] has investigated that the reversibility of electrochemical magnesium deposition on Au and Ag substrates in Grignard reagent/ether solutions. The magnesium deposits on Au and Ag substrates have smooth and compact morphologies. Aurbach et al. [10][11][12][13][14] studied the electrochemical deposition-dissolution mechanisms of magnesium on Au substrates in different ethereal solutions of complexes of the Mg(AX 4n R n′ R′ n″ ) 2 type (A=Al, B; X=Cl, Br; R, R′= alkyl or aryl groups; and n′+n″=n) by using various analytical techniques. They found that the electrolyte was a key factor on morphologies of the magnesium deposits. Nuli et al. [15,16] reported that electrochemical deposition-dissolution processes of magnesium in both ionic liquid electrolytic solutions of BMIMBF 4 and PP13TFSI with 1 mol L 1 Mg(CF 3 SO 3 ) 2 are highly reversible. Wang et al. [17] have studied the electrochemical magnesium deposition-dissolution behavior in a mixed ionic liquid of BMIMBF 4 and PP13TFSI with the volume ratios of 2 : 1, 3 : 1, and 4 : 1 in the presence of 0.3 mol L 1 Mg(CF 3 SO 3 ), respectively. They found that those mixed electrolyte systems were well compatible with the deposition-dissolution of magnesium

Liquid electrolytes with boroxine compounds were prepared, and interfacial reactions at the liquid electrolytes/LiMn 2 O 4 thin-film electrodes were investigated. Boroxine compounds, B 3 O 3 ͑OR͒ 3 , with different kinds of substituents ͓R = CH 3 , CH 2 CH 3 , ͑CH 2 ͒ 2 CH 3 , and CH͑CH 3 ͒ 2 ͔ were dissolved in 1 mol kg −1 LiCF 3 SO 3 /ethylene carbonate + EMC ͑1:1 by volume͒. Both cyclic voltammetry and electrical impedance spectroscopy measurements revealed that interfacial resistance depended on the chain length in the substituent of the boroxine compounds, and the resistance decreased with the increase in the chain length. Moreover, the anodic stability of the electrolytes was improved up to 5.0 V ͑vs Li/Li + ͒ on the film electrodes by the addition of tri-isopropoxy boroxine ͓R = CH͑CH 3 ͒ 2 ͔ with a steric structure ͑branched chain substituent͒. These results indicate that mixing boroxine compounds with both appropriate chain length and steric structure can be an effective way to develop advanced liquid electrolytes for high voltage rechargeable lithium ion batteries.
