Electrical energy storage system such as secondary batteries is the principle power source for portable electronics, electric vehicles and stationary energy storage. As an emerging battery technology, Li-redox flow batteries inherit the advantageous features of modular design of conventional redox flow batteries and high voltage and energy efficiency of Li-ion batteries, showing great promise as efficient electrical energy storage system in transportation, commercial, and residential applications. The chemistry of lithium redox flow batteries with aqueous or non-aqueous electrolyte enables widened electrochemical potential window thus may provide much greater energy density and efficiency than conventional redox flow batteries based on proton chemistry. This Review summarizes the design rationale, fundamentals and characterization of Li-redox flow batteries from a chemistry and material perspective, with particular emphasis on the new chemistries and materials. The latest advances and associated challenges/ opportunities are comprehensively discussed.

A B S T R A C TThe classic poly(ethylene oxide) (PEO) based solid polymer electrolyte suffers from poor ionic conductivity of ambient temperature, low lithium ion transference number and relatively narrow electrochemical window (<4.0 V vs. Li + /Li). Herein, the carbonate-linked PEO solid polymer such as poly (diethylene glycol carbonate) (PDEC) and poly(triethylene glycol carbonate) (PTEC) were explored to find out the feasibility of resolving above issues. It was proven that the optimized ionic conductivity of PTEC based electrolyte reached up to 1.12 Â 10 À5 S cm À1 at 25 C with a decent lithium ion transference number of 0.39 and a wide electrochemical window about 4.5 V vs. Li + /Li. In addition, the PTEC based Li/LiFePO 4 cell could be reversibly charged and discharged at 0.05 C-rates at ambient temperature. Moreover, the higher voltage Li/LiFe 0.2 Mn 0.8 PO 4 cell (cutoff voltage 4.35 V) possessed considerable rate capability and excellent cycling performance even at ambient temperature. Therefore, these carbonate-linked PEO electrolytes were demonstrated to be fascinating candidates for the next generation solid state lithium batteries simultaneously with high energy and high safety.

The flammability of conventional alkyl carbonate electrolytes hinders the integration of large-scale lithium-ion batteries in transportation and grid storage applications. In this study, we have prepared a unique nonflammable electrolyte composed of low molecular weight perfluoropolyethers and bis(trifluoromethane)sulfonimide lithium salt. These electrolytes exhibit thermal stability beyond 200°C and a remarkably high transference number of at least 0.91 (more than double that of conventional electrolytes). Li/LiNi 1/3 Co 1/3 Mn 1/3 O 2 cells made with this electrolyte show good performance in galvanostatic cycling, confirming their potential as rechargeable lithium batteries with enhanced safety and longevity.fluorinated polymers | nonflammable electrolytes L arge-scale rechargeable batteries are expected to play a key role in today's emerging sustainable energy landscape (1, 2). State-of-the-art lithium (Li) batteries not only are used to power zero-emission electric vehicles, but they currently are gaining traction as backup power in aircraft and smart grid applications (3, 4). The electrolyte used in these batteries, however, hinders their use in large-scale applications: it contains a flammable mixture of alkyl carbonate solvents that frequently leads to safety issues. Dimethyl carbonate (DMC), an important component in commercial Li-ion battery electrolytes, has an HMIS (Hazardous Materials Identification System) flammability rating of 3 on a scale of 0-4, indicating a high risk of ignition under most operating conditions. The intrinsic instability of carbonate-based solvents worsens at higher temperatures, at which exothermic electrolyte breakdown often leads to thermal runaway (5, 6), resulting in catastrophic failure of the battery. Although this failure rate stands at about one in ten million systems, it is intolerable for large-scale applications in which cost and user safety might be heavily compromised. This necessitates the development of radically new electrolytes with improved safety.Desirable electrolyte properties include a large window of phase stability (no vaporization or crystallization), complete nonflammability, a wide electrochemical stability window, and suitable ionic transport for the targeted application. There are many approaches to synthesizing materials with these properties, e.g., ionic liquids (7, 8), gel-polymer matrices (9, 10), and small molecule additives (11-13). Systems using poly(ethylene oxide) (PEO) also are well studied (14,15). PEO can solvate high concentrations of lithium salts and is considered nonflammable. Unfortunately, practical conductivity often is limited within a high temperature range (14), and it is well known that in these systems, the motion of the Li ion carries only a small fraction of the overall current (also known as the Li-ion transference number, t + ). PEO-based electrolytes typically exhibit t + values between 0.1 and 0.5 (16-20), leading to strong salt concentration gradients across the electrolytes that limit power density. Recently, we repor...
