“…The binders most commonly used in Li/S cells are polymeric materials which may be (a) ionically conducting, like PEO [11,12,33,35,[39][40][41], nafion [42], polyacrylic acid (PAA) [43], (b) electronically conducting, like polyanilines and polypyrroles [44,45], or (c) inert, like poly(tetrafluoro ethylene) (PTFE) [46][47][48], fluorinated polymers like PVdF and poly(vinylidenefluoride-co-hexafluoro propylene) (PVdF-HFP) [31,44,[49][50][51][52], polyvinylpyrrolidone (PVP) [53], gelatin [54,55], carboxymethylcellulose (CMC) and styrene-butadiene rubbers [13,56,57]. The binder has to strongly bind the positive active material and conductive agent to the current collector and enhance the mechanical integrity of the electrode.…”

Lithium batteries based on elemental sulfur as the cathode-active material capture great attraction due to the high theoretical capacity, easy availability, low cost and non-toxicity of sulfur. Although lithium/sulfur (Li/S) primary cells were known much earlier, the interest in developing Li/S secondary batteries that can deliver high energy and high power was actively pursued since early 1990's. A lot of technical challenges including the low conductivity of sulfur, dissolution of sulfurreduction products in the electrolyte leading to their migration away from the cathode, and deposition of solid reaction products on cathode matrix had to be tackled to realize a high and stable performance from rechargeable Li/S cells. This article presents briefly an overview of the studies pertaining to the different aspects of Li/S batteries including those that deal with the sulfur electrode, electrolytes, lithium anode and configuration of the batteries.

This review article mainly encompasses on the state-of-the-art electrolytes for lithiumsulfur batteries. Different strategies have been employed to address the issues of lithiumsulfur batteries across the world. One among them is identification of electrolytes and optimization of their properties for the applications in lithium-sulfur batteries. The electrolytes for lithium-sulfur batteries are broadly classified as (i) non-aqueous liquid electrolytes, (ii) ionic liquids, (iii) solid polymer, and (iv) glass-ceramic electrolytes. This article presents the properties, advantages, and limitations of each type of electrolytes. Also, the importance of electrolyte additives on the electrochemical performance of Li-S cells is discussed.

“…For example, tetrahydrofuran (THF) (Hamlen et al 2001), 1,3-dioxolane (DOXL) (Chang et al 2002;Wang et al 2010a;Jin et al 2003), dimethoxy ethane (DME), carbonates (Wang et al 2003(Wang et al , 2004a) and polyethylene glycol dimethyl ethers (PEGDME) (Ryu et al 2005;Wang et al 2010a;Choi et al 2008;Cheon et al 2003a, b;Ryu et al 2006a) have been investigated. Among these electrolytes, tetra(ethylene glycol)dimethyl ether (TEGDME), a dimethyl terminated polyethylene oxide oligomer, has been found to be particularly attractive.…”

“…Significantly, a cell employing a solution of 5 vol.% toluene in TEGDME was reported to maintain a discharge capacity of 533 mAh/g following 50 cycles at a low rate (1/16C) and exhibited near stable impedance spectra on cycling. Mikhaylik and Akridge (2003) and Ryu et al (2006a) both show that the performance of TEGDME electrolytes in Li/S cells is markedly worse at low temperatures. By adding 1,3-dioxolane (DOXL) and methylacetate (MA) to the TEGDME electrolyte in the ratio of MA:DOXL:TEG-DME-5:47.5:47:5, by volume-Ryu et al observed that the first discharge capacity could be significantly improved to 994 mAh g -1 at -10°C from 357 mAh/g.…”

From aqueous liquid electrolytes for lithiumair cells to ionic liquid electrolytes that permit continuous, high-rate cycling of secondary batteries comprising metallic lithium anodes, we show that many of the key impediments to progress in developing next-generation batteries with high specific energies can be overcome with cleaver designs of the electrolyte. When these designs are coupled with as cleverly engineered electrode configurations that control chemical interactions between the electrolyte and electrode or by simple additives-based schemes for manipulating physical contact between the electrolyte and electrode, we further show that rechargeable battery configurations can be facilely designed to achieve desirable safety, energy density and cycling performance.
