Al-Zn alloy/MnO2, seawater cell was considered as a primary aqueous cell with an average voltage range from 1.0 to 1.1V, and the electrolyte of seawater was uptaken into the cell. Eventually, the capacity of its usage will be used for long-term. However, the more use of this cell, the higher corrosion phenomenon of the electrode occurred. Due to its corrosion phenomenon, one main default has been observed with gradual decrease during a discharge process. In this research, a common-used active material for anode was LiNiO2. An active material for cathode, ZnXFeS2 was synthesized in high temperature by uptaken a small amount of 1.3 wt% of ZnS into FeS2, one of the transition-metal dichalcogenides in high temperature. Consequently, based on their usages shown above, this secondary aqueous lithium cell could be more developed. This cell was shown as remarkable charge/discharge performance during the charge/discharge processes. This cathode with active material was given a considerable efficiency of inserting Li+ ions. Moreever, in accordance with the characteristic of the crystal structure for ZnxFeS2, a small amount of ZnS was added which made it possible to reduce prominently velocity of corrosion during the charge/discharge cycle. By applying those merits, Al-Zn alloy/MnO2 seawater cell will be used as a fundamental data in order to transform into a secondary aqueous cell.
