Abstract
The micromorphology of zinc electrodeposited at different currents in the flowing electrolyte was studied.It has been shown that the structure of the zinc became compacted with the increase of the charge current density and no zinc dendrite was presenct.A cell with 2Ah capacity was assembled and the charge-discharge test was performed.The results showed that the average charge voltage was 1.84V and the average discharge voltage was 1.65V.The high efficiencies can be achieved with an average coulombic efficiency of 97% and energy efficiency of 86% over 1000 cycles.
