Zinc–air battery’s
cyclelife is mainly related to the dendritic growth of zinc electrodepostion,
morphology shape change of zinc electrode, and the air
electrode failure. Firstly, the formation of dendrites is mostly
dependent on critical overpotential at the tip of dendrites [12]. In
addition, zincate concentration, electrolyte concentration, temperature,
viscosity and velocity of aqueous solution [13] are also
limiting factors of dendritic growth. There are some effective measures
to hinder the dendritic growth including current pulses [14]
and hydrodynamic conditions
