INTRODUCTION
A zinc-bromine battery is a type of rechargeable battery that generates electricity through the reaction of zinc metal with bromine in the presence of an electrolyte made of an aqueous solution of zinc bromide. For stationary power applications, ranging from home to grid-scale, it is being developed as a substitute for lithium-ion batteries.
In comparison to lithium-ion battery systems, the water-based electrolyte makes the battery system less prone to overheating and fire.Zinc and bromide ions are created at the appropriate electrodes during discharge.
The zinc deposit is unable to absorb bromine due to the microporous separator between the electrode surfaces, which lessens the direct chemical reaction and the cell’s related self-discharge.
GLOBAL ZINC-BROMINE FLOW BATTERY MARKET SIZE AND FORECAST
The Global Zinc-bromine flow Battery Market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
RECENT DEVELOPMENT
Zinc-bromine redox flow batteries with superpower density.A new technique to develop effective electrode materials for powerful redox flow battery (RFB) systems. Their flow cell, which had a heat-treated nickel-rich platinum-nickel coating on the graphite felt, achieved an amazing all-time high power density of roughly 1,550 mW cm2.
Unlike vanadium redox flow batteries, which have a low intrinsic energy density, zinc-bromine RFBs have a high theoretical energy density (440 Wh/kg). However, the low kinetics and reversibility of Br2/Br redox activity are substantial impediments to realising that promise.
To improve flow cell performance, researchers at India’s Central Electrochemical Research Institute (CECRI) created a graphite felt (GF) supported platinum-nickel (PtNi) bimetallic alloy-based electrode. The 3D structure GF-based metal particles decorated electrode-based flow cells performed well under all test conditions.
The superpower density of the Ni-rich based flow cell was higher than that of the bare GF-based flow cell. With coulombic, voltage, and energy efficiency, the cycle life demonstrated outstanding stability up to 300 cycles.
