“…[117][118][119][120][121][122][123] For example, the electrochemical characteristics of EDLCs consisting of electrodes of microporous titanium carbide derived carbon (TiC-CDC) were studied in 1.0 mol L ─1 (C2H5)3CH3NBF4/PC solutions with several additives, such as diethyl sulfite (DES) and 1, 3-propylene sulfite (PS). [117][118][119][120] These additives are actually well-known for LIBs. The results showed that DES and PS additives could obviously change both the viscosity and conductivity of PC-based electrolytes, affecting the capacitance and the characteristic time constant, and the power and energy values of the obtained EDLCs (see Fig.…”

Name., 2013, 00, 1-3 | 1 Electrolyte is a key component of electrochemical energy storage (EES) devices and its properties greatly affect the energy capacity, rate performance, cyclability and safety of all EES devices. This article offers a critical review of recent progresses and challenges in electrolyte research and development particularly for supercapacitors and supercapatteries, recharegable batteries (such as lithium-ion and sodium-ion batteries), and redox flow batteries (including fuel cells in a broad sense). The review will focus on liquid electrolytes, particularly aqueous and organic electrolytes, ionic liquids and molten salts. Influences of electrolyte properties on the performances of different EES devices are discussed in detail.

Electrolyte solutions, containing the lithium sulfonyl methide salts lithium-tris(trifluoromethanesulfonyl)methide (LiTFSM) and lithium-[bis(trifluoromethylsulfonyl)-pentafluoroethylsulfonyl]methide (LiPFSM) dissolved in organic carbonate solvents, were electrochemically investigated in Li/graphite, Li/LiNi 1/3 Co 1/3 Mn 1/3 O 2 (NCM) half-cells and compared to the LiPF 6 based electrolyte with regard to their ionic conductivity, electrochemical stability, thermal stability at 60 • C and the anodic dissolution behavior vs. Al. While the investigated salts show almost the same performance in Li/graphite half-cells compared to the LiPF 6 containing electrolyte, the methide salts show very promising results in Li/NCM half-cells, which depict superior capacity retention as well as higher Coulombic efficiencies compared to the LiPF 6 containing electrolyte. Taking the limited anodic stability as well as the occurring anodic dissolution into account, both salts but especially LiTFSM indicate the applicability in lithium ion battery electrolytes for cells with a cutoff potential up to 4. In the last 25 years the demand for lithium-ion batteries has grown tremendously. As a consequence, fundamental research has been carried out regarding the improvement and understanding of technological and safety related aspects. [1][2][3][4][5][6][7][8] Individual applications demand specifically tailored batteries in order to maximize the performance of the device which depicts a great challenge and opportunity for the scientific community to diversify the spectrum of compounds that can be utilized and to adapt the setup in a fast and efficient manner. 9,10 In this respect, the electrolyte, as a multifunctional battery component, can consist of a wide array of compounds such as different solvents, conductive salts and numerous additives. The combination of various electrolyte compounds opens up the possibility to tailor the electrolyte and thus, to a significant extent, the battery cell performance. 11-14The current state-of-the-art electrolyte composition is comprised of the conductive salt lithium hexafluorophosphate (LiPF 6 ) dissolved in a mixture of cyclic (e.g. ethylene carbonate and propylene carbonate [15][16][17][18][19] ) and linear carbonates (e.g. dimethyl-, diethyl-and ethyl-methyl carbonate). 11,[19][20][21][22][23][24][25] However, with increasing demands on the electrolyte regarding thermal and/or electrochemical stability, the limitations of such electrolyte mixtures are unraveled. 11,26,27 Alternative electrolyte compositions that depict certain improvements compared to the state-of-the-art electrolyte are still required to fulfil the following properties: a sufficient ionic conductivity to transport the lithium ions, the ability to form an effective solid electrolyte interphase (SEI) on the graphitic anode 28-37 which enables stable cycling in the low potential range as well as inertness toward aluminum to avoid anodic dissolution of the current collector on the cathode side. 38,39 In addition to performance, more...

“…[7,8] Unlike ethylene carbonate, propylene carbonate (PC) is considered as a safe low-temperature electrolyte. [8,9] However, the PC solvent and the solvated Li + ions tend to cointercalate into graphite accompanied by severe exfoliation of graphite layers and thus destruction of the graphite structure. [8,9] What is very noteworthy is the excellent cycling performance in a PCbased electrolyte at a rate of C/5 (Fig.…”
