Are membrane-free batteries cyclable?

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.

What is a membrane-free redox flow battery?

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.

Can membrane-free flow batteries be used for energy storage?

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.

Are membrane-free Zn/phenothiazine batteries based on biphasic electrolytes?

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].

Are non-aqueous electrolytes-based redox flow batteries a promising energy storage technology?

Non-aqueous electrolytes-based redox flow batteries have emerged as promising energy storage technologies for intermittent large-scale renewable energy storage, yet the development of non-aqueous electrolytes-based redox flow batteries has been hindered by the lack of ionic exchange membrane.

What is a membrane-free battery?

This proof-of-concept of a membrane-free battery has an open circuit voltage of 1.4 V with a high theoretical energy density of 22.5 Wh L −1, and is able to deliver 90 % of its theoretical capacity while showing excellent long-term performance (coulombic efficiency of 100 % and energy efficiency of 70 %).
