“…[11][12][13][14] Thus, besidest he conventional,o rganic carbonatebased electrolytes, which are known to undergos evere degradation upon ORR and subsequentO ER, [13,15] several other electrolytesh ave been proposed. The most promising electrolytes include polymers, [8,16] LISICONs, [17,18] ethers, glymes,n itriles, amides, sulfones,D MSO-based, and ionic liquids( ILs). [10,[19][20][21] Electrolyte choice plays crucial role in determining the reaction pathway (i.e.,s olution mechanism vs. surface mechanism), [22] which is particularly affected by superoxide (LiO 2 ) [23] and oxygen [24] solubility in the solventm edia, with ad irect consequenceo nr eactionk inetics.…”

Cathode configurations reported herein are alternative to the most diffused ones for application in lithium-oxygen batteries, using an ionic liquid-based electrolyte. The electrodes employ high surface area conductive carbon as the reaction host, and polytetrafluoroethylene as the binding agent to enhance the oxygen reduction reaction (ORR)/oxygen evolution reaction (OER) reversibility. Roll-pressed, self-standing electrodes (SSEs) and thinner, spray deposited electrodes (SDEs) are characterized in lithium-oxygen cells using an ionic liquid (IL) based electrolyte formed by mixing lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) salt and N,N-diethyl-N-(2-methoxyethyl)-N-methylammonium bis(trifluoromethanesulfonyl)imide (DEMETFSI). The electrochemical results reveal reversible reactions for both electrode configurations, but improved electrochemical performance for the self-standing electrodes in lithium-oxygen cells. These electrodes show charge/discharge polarizations at 60 °C limited to 0.4 V, with capacity up to 1 mAh cm and energy efficiency of about 88 %, while the spray deposited electrodes reveal, under the same conditions, a polarization of 0.6 V and energy efficiency of 80 %. The roll pressed electrode combined with the DEMETFSI-LiTFSI electrolyte and a composite Li Sn-C alloy anode forms a full Li-ion oxygen cell showing extremely limited polarization, and remarkable energy efficiency.

“…Furthermore, the crystals of Li 2 O 2 necessary for electrochemical regeneration can be nucleated away from the carbon grains/nanotubes. To avoid this problem, a redox mediator (RM) can be used in GPEs [388,428,432,433]. During charging, the RM first undergoes electrochemical oxidation into RM ox at the cathode side.…”

“…The capacity retention at 1C was 89% after 100 cycles [478]. Note, however, that Li-Nafion, which has also been tested in Li–O 2 batteries [433], is expensive and that pure Li-Nafion alone cannot be used as an electrolyte because its mechanical strength is too low.…”

Building Better Batteries in the Solid State: A Review

Most of the current commercialized lithium batteries employ liquid electrolytes, despite their vulnerability to battery fire hazards, because they avoid the formation of dendrites on the anode side, which is commonly encountered in solid-state batteries. In a review two years ago, we focused on the challenges and issues facing lithium metal for solid-state rechargeable batteries, pointed to the progress made in addressing this drawback, and concluded that a situation could be envisioned where solid-state batteries would again win over liquid batteries for different applications in the near future. However, an additional drawback of solid-state batteries is the lower ionic conductivity of the electrolyte. Therefore, extensive research efforts have been invested in the last few years to overcome this problem, the reward of which has been significant progress. It is the purpose of this review to report these recent works and the state of the art on solid electrolytes. In addition to solid electrolytes stricto sensu, there are other electrolytes that are mainly solids, but with some added liquid. In some cases, the amount of liquid added is only on the microliter scale; the addition of liquid is aimed at only improving the contact between a solid-state electrolyte and an electrode, for instance. In some other cases, the amount of liquid is larger, as in the case of gel polymers. It is also an acceptable solution if the amount of liquid is small enough to maintain the safety of the cell; such cases are also considered in this review. Different chemistries are examined, including not only Li-air, Li–O2, and Li–S, but also sodium-ion batteries, which are also subject to intensive research. The challenges toward commercialization are also considered.

“…[12] Then, varieties of solid polymer electrolytes emerged, prepared by incorporating lithium salts or organic electrolyte solution containing lithium salts into polymer matrices, such as PAN, [12] PEO, [218,268] poly(vinylidene fluoride-co-hexafluoropropylene) (P(VdFHFP)), [269,270] and others polymer materials. [271][272][273] Solid polymer electrolyte attracts researchers' attention because of easy fabrication, flexibility and good protection for Li metal anode from O 2 or H 2 O. Scrosati et al systematically investigated the reaction chemistry of a solid state LOBs based on PEO-based polymer electrolyte composite. However, the practical application of solid polymer electrolyte in lithium-oxygen battery still suffers from severe issues: low Li ion conductivity and instability against reactive oxygen species.…”

is restricted to their inferior energy densities (≈250 Wh kg −1) due to intercalation chemistry. Consequently, "beyond Li-ion batteries" such as lithium-sulfur batteries and metal-air batteries, which have fundamental discrepant energy storage mechanism, have been attracted worldwide attention recently. [4,5] Of all the candidates, rechargeable lithium-oxygen battery (LOB) is considered to be one of the most fascinating next-generation batteries with extremely high theoretical energy density (≈3500 Wh kg −1). [6,7] The low-cost and environmental positive active material oxygen originates from air, endowing LOBs more attractive to satisfy the soaring demand of large-scale energy storage system. Generally, there are four architecture systems of LOBs determined by different electrolyte: aqueous, nonaqueous, hybrid, and all-solid-state. [8-11] In 1996, Abraham and Jiang first reported the rechargeable lithium-oxygen battery consisted of Li metal anode, solid polymer electrolyte membrane, and composite carbon cathode. [12] After ten years, nonaqueous LOBs actually caught worldwide attention due to the outstanding capacity and reversibility. [6] A typical nonaqueous lithium-oxygen battery comprises a metallic Li anode, organic electrolyte containing Li salt, a separator, and a porous gas diffusion cathode loading with catalysts (Figure 1). [13] Generally, the electrochemical reactions of nonaqueous lithium-oxygen battery can be described as following equations [14-16] Overall reaction E 2Li O Li O 2.96 V vs Li/Li 2 2 2 () + ↔°= + (1) Cathodic process (oxygen reduction reaction (ORR))
