“…From the enhanced cell performance, it can be concluded that anchoring of AC on the graphite felt improved the bromine reversibility. The enhancement in the bromine reversibility is due to the intertwine behavior of bio‐mass derived AC which provides large number of electrochemical active sites in the form of hydroxyl and carboxylic functional groups which is well supported from the FTIR studies …”

There has been a huge demand on the usage of biomass‐derived activated carbon as an electrode and electrocatalyst for energy storage and conversion applications owing to its abundance, high surface area, good chemical stability, low cost, and eco‐friendliness. Herein, we report for the first time, activated carbon (AC) derived from Phyllanthus Emblica Leaves (PEL) (Indian gooseberry) biomass as an electrocatalyst for enhancing the bromine electro‐kinetics. The AC‐anchored graphite felt (AC−GF) showed excellent improvement in the bromine reversibility, which reinforces the overall performance of the zinc bromine redox flow battery (ZBRFB). Specifically, the AC−GF showed significant improvement in voltage efficiency. The flow cell employing AC in the positive electrode showed high Coulombic, voltage, and energy efficiency of 99, 83 and 82 %, respectively at a current density of 30 mA cm−2. Furthermore, the cell showed good cycle performance with 96.43 % Coulombic efficiency retention even after 100 cycles. Thus, the significant improvement in the cell performance unveils the good electrochemical/catalytic activity of the AC and therefore can be used as a potential low‐cost electrocatalyst in ZBRFB.

Biomass‐derived carbon materials have received special attention as efficient, low‐cost, active materials for charge‐storage devices, regardless of the power system, such as supercapacitors and rechargeable batteries. In this Minireview, we discuss the influence of biomass‐derived carbonaceous materials as positive or negative electrodes (or both) in high‐energy hybrid lithium‐ion configurations with an organic electrolyte. In such hybrid configurations, the electrochemical activity is completely different to conventional electrical double‐layer capacitors; that is, one of the electrodes undergoes a Faradaic reaction, whilst the counter electrode undergoes a non‐Faradaic reaction, to achieve high energy density. The use of a variety of biomass precursors with different properties, such as surface functionality, the presence of inherent heteroatoms, tailored meso‐/microporosity, high specific surface area, various degrees of crystallization, calcination temperature, and atmosphere, are described in detail. Sodium‐ion capacitors are also discussed, because they are an important alternative to lithium‐ion capacitors, owing to the low abundance and high cost of lithium. The electrochemical performance of carbonaceous electrodes in supercapacitors and rechargeable batteries are not discussed.

SummaryAn increasing fraction of energy is generated by intermittent sources such as wind and sun. A straightforward solution to keep the electricity grid reliable is the connection of large-scale electricity storage to this grid. Current battery storage technologies, while providing promising energy and power densities, suffer from a large environmental footprint, safety issues, and technological challenges. In this paper, the acid base flow battery is re-established as an environmental friendly means of storing electricity using electrolyte consisting of NaCl salt. To achieve a high specific energy, we have performed charge and discharge cycles over the entire pH range (0-14) at several current densities. We demonstrate stable performance at high energy density (2.9 Wh L −1 ). Main energy dissipation occurs by unwanted proton and hydroxyl ion transport and leads to low coulombic efficiencies (13%-27%). Although the CGFB has low environmental impact, energy density and power density are too low to be attractive for practical application. KEYWORDSIn this work, we show that the energy density and power density of the CGFB can be improved by implementing a bipolar membrane. The studied system is an energy storage system based on a reversible acid-base reaction. In this system called acid base flow battery (AB-FB), energy is being stored in acid and base solutions created by the bipolar membrane. The charge step of the AB-FB is similar to the well-known bipolar membrane electro dialysis (BPM-ED). BPM-ED converts NaCl solutions into NaOH and HCl solutions by spending electric power to separate protons and hydroxyl ions from water dissociation from the bipolar ----------------------------------------------------This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.
