“…Sugar cane bagasse is another abundant biowaste material that has been reported for the synthesis of AC. By carbonizing at 700 • C with the aid of KOH activation under nitrogen atmosphere, a BET surface area of 1255 m 2 g −1 was achieved [66]. The of AC-modified graphene felt electrode showed a reduction in the peak separation (∆E p ) to 354 mV (vs 596 mV for thermally treated GF) and higher current at any given potential, as well as nearly 119 times lower charge transfer resistance.…”

The development of alternative energy storage technologies is key to advance renewable energy resources. Among them, redox flow batteries (RFBs) have been identified to be one of the most promising technologies in the field of stationary batteries. The carbon-based electrodes in these batteries are a crucial component and play an important part in achieving high efficiency and performance. A further leap into this direction is the design of fossil-free materials by incorporating sustainable alternative resources as the carbon component in the processing of the electrodes. The use of biomass as carbon precursor for electrode applications has also been a focus of research for other energy storage devices and in the case of RFBs, it has become an emergent topic in recent years. This short review presents the recent advances in the design of biomass-derived carbon materials as electrodes in RFBs, strategies to enhance their electrocatalytic properties, challenges, and future outlook in the design of sustainable electrode materials.

“…Mesoporous AC materials are produced from bio and industrial waste materials via carbonization. Recently, AC extracted from bio‐waste coconut shell (Ulaganathan et al, 2015) and sugarcane bagasse (Mahanta et al, 2019) were reported as electrocatalyst in VRFB. Mesoporous AC derived from carbon precursor of coconut shell (particles size: 20–30 mesh) and then heated at ~800°C under N 2 and CO 2 flow.…”

Attractive features of vanadium redox flow battery (VRFB) such as long durability, easy scalability, and low levelized cost of energy have influenced its prominence in the sectors where renewable energy is to be stored at a large scale. However, viability of VRFB to be used for a wide‐range of applications such as household electrification, electric vehicle charging infrastructure, and so on has been limited by its low power density. In principle, the power density of VRFB is dependent upon rate of electrochemical reaction on the electrode. The electrochemical properties of the electrode can be improved either by pretreatment of the electrode or by depositing electrocatalyst on the electrode. The use of electrocatalyst helps to lower overpotential losses and reduces the charge‐transfer resistance, which results the VRFB to operate at higher current densities. This review discusses the development and progress of carbon and metal‐based electrocatalyst that have been used for VRFB applications.

“…In carbon‐based catalysts, carbon should have high conductivity and excellent stability. Carbon nanotubes, graphene, and activated carbon have been generally used for this purpose [42–44] . Of them, activated carbons have cost benefits when compared to other carbon candidates, while these can be easily fabricated by (i) new cheap raw materials or (ii) doping desirable functional groups onto their surface through heat and acidic treatments.…”

Carbonized and activated low-density polyethylene (LDPE) is suggested as a carbon catalyst for vanadium redox flow battery (VRFB). This carbon catalyst has many surface oxygen functional groups and a large surface area, while such benefits are achieved through activation of carbonized LDPE. According to electrochemical analysis, this carbon catalyst doped graphite felt (GF) enhances the redox reactivity of vanadium ions. More specifically, peak current density and peak potential separation for redox reaction of vanadium ions are 96.0 and 22.1% more improved than those measured by bare GF, while charge transfer resistance for the redox reactions is also improved by use of the catalyst doped GF. When performance of VRFB using this catalyst doped GF is measured, energy efficiency is 39% more improved than that measured without the catalyst. Based on that, this is revealed that new LDPE-based carbon catalyst is effective for performance improvement of VRFB.
