“…With the increasing recognition of the benefits of adopting novel electrolytes (e.g., the nonaqueous electrolytes and hybrid electrolytes discussed in Section 2) for Zn-air batteries, there is a need to explore a suitable cell configuration for these new electrolyte systems. A good example was shown in a pioneering study, where Chou et al [106] utilized a hybrid electrolyte system to develop stationary batteries for storing renewable energy. The cell configuration employed three different electrolytes: an RTIL containing electrolyte for the Li anode side (to reduce Li dendrite formation), a ceramic solid-state electrolyte as the separator (to prevent the penetration of Li dendrites) and an aqueous electrolyte for the MnO 2 cathode side (for high cycle life).…”

“…As an alternate approach, a solid electrolyte can be used to allow the use of lithium metal anode in combination with aqueous electrolytes [14][15][16][17]. Such hybrid devices merges the advantages of pseudo-capacitive electrodes, which can only provide high capacitance in aqueous electrolytes, and the low standard electrode potential of Li, which can only be used in non-aqueous electrolytes.…”

Water-stable multi-layered lithium-doped carbon (LixC6) negative electrode using poly(ethylene oxide) (PEO)-lithium bis(trifluoromethansulfonyl)imide (LiTFSI) polymer electrolyte containing N-methyl-N-propylpiperidinium bis(trifluoromethansulfonyl)imide (PP13TFSI) ionic liquid was developed. Electrochemical properties at 60˚C of the aqueous hybrid supercapacitor using activated carbon positive electrode and a multi-layered LixC6 negative electrode (LixC6 | PEO-LiTFSI | LTAP) without PP13TFSI exhibited performance similar to that using Li anode (Li | PEO-LiTFSI | LTAP). A drastic decrease in ESR was achieved by the addition of PP13TFSI to PEO-LiTFSI, allowing room temperature operation. The ESR of the multi-layered LixC6 negative electrode with PEO-LiTFSI-PP13TFSI at 25˚C was 801  cm 2 , which is 1/6 the value of the multi-layered Li negative electrode with PEO-LiTFSI (5014  cm 2). Charge/discharge test of the aqueous hybrid supercapacitor using multilayered LixC6 negative electrode with PEO-LiTFSI-PP13TFSI at 25˚C afforded specific capacity of 20.6 mAh (g-activated carbon) 1 with a working voltage of 2.7-3.7 V, and good long-term capability up to 3000 cycles. Furthermore, an aqueous hybrid supercapacitor consisting of a high capacitance RuO2 nanosheet positive electrode and multi-layered LiC6 negative electrode with PEO-LiTFSI-PP13TFSI showed specific capacity of 196 mAh (g-RuO2) 1 and specific energy of 625 Wh (kg-RuO2) 1 in 2.0 M acetic acid-lithium acetate buffered solution at 25˚C.

“…This means that, for example, lithium ion RFBs must achieve discharge power densities of at least 30 mW/cm 2 for the system costs to be the same as for a VRFB. Some current lithium ion RFBs are several orders of magnitude below this value [25][26][27][28]. The current densities of commercial lithium ion batteries lie within the single-digit mA range; they only have large electrode areas-and hence acceptable volumetric power densities-because of their comparatively extremely thin construction [29].…”

Abstract:A techno-economic model was developed to investigate the influence of components on the system costs of redox flow batteries. Sensitivity analyses were carried out based on an example of a 10 kW/120 kWh vanadium redox flow battery system, and the costs of the individual components were analyzed. Particular consideration was given to the influence of the material costs and resistances of bipolar plates and energy storage media as well as voltages and electric currents. Based on the developed model, it was possible to formulate statements about the targeted optimization of a developed non-commercial vanadium redox flow battery system and general aspects for future developments of redox flow batteries.
