Nanocatalyzed PtNi Alloy Intact @3D Graphite Felt as an Effective Electrode for Super Power Redox Flow Battery

A zinc-bromine redox flow battery (RFB) is highly suitable for high-energy storage due to its decoupled energy and power generation. However, the poor kinetics reversible behavior of Br2/Br− activity are some significant barriers, as a result, system delivers low density. To increase efficiency cell, in present work, bimetallic catalysts deposited on 3D graphite felt network used positive electrode enhancing reaction. The platinum–nickel (PtNi) composition optimized, improved performances investigated using half-cell flow-cell assembly. parameters high electro-catalytic nature heat-treated Ni-rich PtNi coating (GF) cell operated up 140 mA cm−2. with Pt0.5Ni1@GF an impressive ever-best density around 1550 mW cycle life shows excellent stability 300 cycles coulombic, voltage, 97%, 86%, 83%, respectively. Thus, work offers promising approach developing effective materials obtaining superpower RFB system.
