“…3 shows the results of half-cell measurements on para-benzoquinone and parahydroquinone at concentrations of 0.0925 M and 0.0918 M, respectively, in a 1 N H 2 SO 4 solution at 20C. We see prominent reduction and oxidation peaks for the couple at 0.69 V and 0.17 V, respectively, which is consistent with the previously-observed electrochemical behavior of the para-benzoquinone/para-hydroquinone couple [5,6]. The reduction potential is given to be 0.43 V vs. Ag/AgCl electrode, or equivalently, 0.64 V vs. SHE.…”

At present, there is an ongoing search for approaches toward the storage of energy from intermittent renewable sources like wind and solar. Flow batteries have gained attention due to their potential viability for inexpensive storage of large amounts of energy. While the quinone/hydroquinone redox couple is a widely studied redox pair, its application in energy storage has not been widely explored. Because of its high reversibility, low toxicity, and low component costs, we propose the quinone/hydroquinone redox couple as a viable candidate for use in a grid-scale storage device. We have performed single-electrode tests on several quinone/hydroquinone redox couples, achieving current densities exceeding 500 mA/cm 2 , which is acceptable for use in energy applications. We fabricated a full cell using para-benzoquinone at the positive electrode against a commercial fuel cell hydrogen electrode separated by a Nafion membrane. We evaluated its performance in galvanic mode, where it reached current densities as high as 150 mA/cm 2 . The results from these studies indicate that the quinone/hydroquinone redox couple is a promising candidate for use in redox flow batteries.

“…Therefore, after the first electrochemical study of catechol in the presence of 1,3-cyclopentadiene [10], we now report electrochemical study, electrochemical synthesis and kinetic evaluation of oxidation of 1,4-hydroquinone in the presence of 1,3-cyclopentadiene. Previously we have shown that 1,4-hydroquinone can be oxidized electrochemically to p-benzoquinones and the formed quinone can be attacked as Michael acceptors by a variety of nucleophiles [11][12][13][14][15]. In contrast to our previous works, in this work the electro-generated p-benzoquinone is used as a dienophile.…”

“…The absence of the reverse peak is likely attributed to the instability of the electro-oxidation produced species in alkaline conditions, as also observed in other works. 61,[64][65][66] Post CV, the half-cell OCP for both species drops below −0.6 V vs. SCE, which suggests the formation and presence of a new species in the solution. Despite these indications that both H 2 BQS and AA may not be reversible under alkaline conditions and hence unsuitable for a conventional flow battery application in alkaline conditions, both are still deemed adequate for the primary battery approach presented in this work, since only the electro-oxidation portion of the cycle is of interest.…”

The rate of battery waste generation is rising dramatically worldwide due to increased use and consumption of electronic devices. A new class of portable and biodegradable capillary flow batteries was recently introduced as a solution for single-use disposable applications. The concept utilizes stored organic redox species and supporting electrolytes inside a dormant capillary flow cell which is activated by the dropwise addition of aqueous liquid. Herein, various organic redox species are systematically evaluated for prospective use in disposable capillary flow cells with regards to their electrochemical characteristics, solubility, storability and biodegradability. Qualitative ex-situ techniques are first applied to assess half-cell solubility, redox potential and kinetics, followed by quantitative in-situ measurements of discharge performance of selected redox chemistries in a microfluidic cell with flow-through porous electrodes. Para-benzoquinone in oxalic acid and either hydroquinone sulfonic acid or ascorbic acid in potassium hydroxide are identified for the positive and negative half-cells, respectively, yielding a maximum discharge power density of 50 mW/cm 2 . A prototype capillary flow battery using the same redox chemistries demonstrates robust cell voltages above 1.0 V and maximum discharge power of 1.9 mW. These results show that practical primary battery performance can be achieved with biodegradable chemistries in a disposable device. The market demand for small-size single-use electronic devices such as portable sensors and diagnostic devices has been rising drastically in recent years. The power needs of such devices have so far been met by Li-ion batteries and other primary battery technologies, resulting in a consequent rise in their consumption. These batteries often contain heavy metals and strong electrolytes which make them one of the most hazardous components of electronic waste.1 In addition, the majority of the primary Li batteries used globally are not recycled nor properly disposed of, thus ending up in landfills without regulations.2 In applications that do not require long discharge times and have modest capacity requirements such as medical devices, these batteries are not even fully discharged before being disposed of. This requires further resources for re-extracting the materials if not recovered, which is not sustainable and raises concerns about the abundance of these resources. The end-of-life fate of these batteries and their life cycle assessment therefore only justifies the use in rechargeable applications beyond hundreds of cycles.3,4 These issues trigger a worrying concern about associated future environmental hazards from the battery waste generation and urgently call for novel alternatives, tightened environmental policies and switching the linear consumption habit of "take-make-dispose" for these primary batteries into a circular economy model. This approach utilizes novel concepts such as green electronics and cradle-to-cradle design to eliminate waste from the conc...
