Abstract

Batteries will continue to encounter the problem of dendrite formation until a suitable solution is identified to address the problem. Dendrite formation can short circuit batteries cells, reduce their life span, voltages and cause mechanical abrasion to the cells. Batteries electrodes are part of the approaches that can be used to address these problems but depending on the fabrication of these electrodes and dimensions. Before fabricating and incorporating a real anode reactor to a fabricated ZnBr2 cell system, it was necessary to model the behaviour with injected carbon particles in between 254 microns to 354 microns and simulate the geometry in COMSOL to observe their interaction with the electrolyte. This study investigates the performances of a designed anode reactor and to observe within the reactor the effect of having a uniform and non-uniform current density distribution before the fabrication, physically charge and incorporating it to the anode-side of ZnBr2 cell system.
