Abstract Scope |
Zinc anode is one of the promising candidates for the anode of next-generation batteries such as zinc-nickel and zinc-air cells, while zinc secondary battery has been suffering a poor cycleability due to the generation and growth of zinc dendrite. This paper presents a solution of this problem that is the electrodeposited zinc thin film which works as the active mass and current collector of zinc anode. The voltage performance and capacity retention were examined using zinc-nickel cells and the results demonstrated the discharge capacity maintaining 100% of the initial value and no significant change in charge-discharge voltage even more than 1,900 cycles at 1 C. The polarization of the zinc anode was only 25 mV and the anode’s potential showed no sign of dendrite growth and internal short circuit for the long operation. |
