Figure 6 illustrates the current obtained during the charging and discharging process of the new electrolyte in a membraneless micro redox flow battery, with constant flow rates of 250 μL/min and 200 μL/min for the positive and negative sides, respectively. Like MVMRFB, electrochemical experiments are conducted in potentiostatic mode

Unbound Potential has developed a membrane-less redox flow battery that, unlike conventional lithium-ion batteries, does not require any critical raw materials.. Instead of using a membrane, the ion exchange is controlled by non-miscible electrolytes, which Unbound Potential said makes the battery more durable and requires 90 per cent fewer sealing surfaces.
A membrane-free redox flow battery with high energy density is presented. The designed flow battery delivers a capacity retention of 94.5% over 190 cycles. Operando UV–visible and FT-IR spectroscopies are performed to elucidate capacity decay mechanism.
While membrane-free batteries have been successfully demonstrated in static batteries, membrane-free batteries in authentic flow modes with high energy capacity and high cyclability are rarely reported. Here, we present a biphasic flow battery with high capacity employing organic compound in organic phase and zinc in aqueous phase.
The power density of the membrane-free RFBs can be further improved by decreasing the distance between electrodes and increasing the ionic conductivity of electrolytes. This work opens a new avenue of using membrane-free flow batteries for affordable large-scale energy storage.
Chai et al. also demonstrated a membrane-free Zn/phenothiazine battery based on biphasic electrolytes . Despite the delicate design, most of the reported membrane-free batteries only operate under static conditions with limited scalability, and the membrane-free flow battery is rarely demonstrated [25, 52, 56].
To probe the capacity fade mechanism of the membrane-free batteries, it is essential to first study the stability of the TEMPO and C3-PTZ electrolytes. The CV tests in different systems with or without saturated water were conducted to explore the influence of the water on the redox behavior.
The UV-visible absorption analysis provided evidence that C3-PTZ gradually degrade in this membrane-free battery system. The operando UV-visible spectroscopy demonstrated in this system can be extended to other flow electrochemical systems to help understand a wide range of redox processes.
