Lithium-ion batteries are becoming increasingly important for electrifying the modern transportation system and, thus, hold the promise to enable sustainable mobility in the future. However, their large-scale application is hindered by severe safety concerns when the cells are exposed to mechanical, thermal, or electrical abuse conditions. These safety issues are intrinsically related to their superior energy density, combined with the (present) utilization of highly volatile and flammable organic-solvent-based electrolytes. Herein, state-of-the-art electrolyte systems and potential alternatives are briefly surveyed, with a particular focus on their (inherent) safety characteristics. The challenges, which so far prevent the widespread replacement of organic carbonate-based electrolytes with LiPF6 as the conducting salt, are also reviewed herein. Starting from rather "facile" electrolyte modifications by (partially) replacing the organic solvent or lithium salt and/or the addition of functional electrolyte additives, conceptually new electrolyte systems, including ionic liquids, solvent-free, and/or gelled polymer-based electrolytes, as well as solid-state electrolytes, are also considered. Indeed, the opportunities for designing new electrolytes appear to be almost infinite, which certainly complicates strict classification of such systems and a fundamental understanding of their properties. Nevertheless, these innumerable opportunities also provide a great chance of developing highly functionalized, new electrolyte systems, which may overcome the afore-mentioned safety concerns, while also offering enhanced mechanical, thermal, physicochemical, and electrochemical performance.

“…A C (1s) signal peak was all detected at around 287 eV on the top surface of Al foil after the first and second breakdown potential processes, which originated from the decomposition of the organic solvent in the electrolytes during the anodic polarization processes. The depth profiles for Al foil surface showed that the surface composition after the first and second anodic polarization processes consisted mainly of AlF 3 and Al 2 O 3 . Moreover, the passive film containing Al 2 O 3 did not change, while the thickness of passive film containing AlF 3 increased in the continual anodic polariza- …”

“…Aluminum (Al) is widely used as a kind of current collector in lithium ion batteries, electric double layer capacitors (EDLC) and other electrochemical devices due to its high mechanical strength, excellent ductility, low density, good electrical and thermal conductivity, and also low cost. 3 In electrochemical devices, Al current collector is a key component for electron conduction between electrode materials and the external circuit in lithium ion batteries. The stability of Al current collector is very important to the cycle performance of electrochemical devices.…”

The anodic polarization behavior of Al, Ta and Nb foil was investigated in 1-butyl-3-methylimidazolium tetrafluoroborate ionic liquid (BMI-BF 4 ). Compared with that of Ta and Nb foil, it showed that a better passive film was formed on Al foil surface after the anodic polarization in BMI-BF 4 , which could resist the potential up to 94.58 V vs. Ag ＋ /Ag. Besides, similar anodic behavior of Al foil was observed in N-methyl-N-butylpiperidinium tetrafluoroborate ionic liquid (PP14-BF 4 ), which indicated that the anodic polarization behavior of Al foil was independent of the cations of RTIL. In addition, the investigation of anodic polarization behavior of Al foil was carried out in the mixture electrolytes composed of BMI-BF 4 •PC. Differently, two breakdown potential processes of Al foil were presented compared to pure BMI-BF 4 . Further research showed that the passive film on Al foil was mainly composed of AlF 3 and Al 2 O 3 after the first breakdown potential process, while the fluoride film increased with continual anodic polarization, which improved the anodic stability of Al foil and resisted higher breakdown potential. The high breakdown potential properties of Al foil in BMI-BF 4 , PP14-BF 4 and the mixture of BMI-BF 4 •PC during the anodic polarization can be favored for R&D of the high performance electrochemical devices.

“…SS 304, Ti, Ni and Al are common metals used as current collectors and casing materials in lithium-ion battery, as well as electrodes and bipolar plates in redox flow battery (RFB). [4][5][6][7][8][9] To our knowledge, the corrosion behavior of these metals in non-aqueous electrolytes has not been systematically investigated so far. A thorough study on metal corrosion in commonly used organic solvents would support the development of non-aqueous battery technology.…”

:The corrosion behavior of stainless steel 304 (SS 304), titanium, nickel and aluminium is studied by immersion and anodic polarization tests in non-aqueous electrolytes. Tetraethyl ammonium tetrafluoroborate is used as a supporting electrolyte in the three kinds of solvents. The immersion test shows that chemical corrosion rate in propylene carbonate-based electrolyte is lower than those in acetonitrile-or γ-butyrolactone-based electrolytes. Surface analyses do not reveal any corrosion product formed after the immersion test. In the anodic polarization tests, a higher concentration of supporting electrolyte gives a higher current density. In addition, a higher temperature increases the current density in the active region and reduces the potential range in the passive region. SS 304 shows the highest corrosion potential while Al shows the lowest corrosion potential and the highest current density in all studied conditions. Based on the conducted corrosion tests, the corrosion resistance of metal substrates in the organic solvents can be sorted in descending order as follows: SS 304 -Ti -Ni -Al.
