A novel method of preparing the silver chloride cathode for the magnesium seawater activated primary cell

Abstract The novel method based on the inexpensive and fast modified successive ion layer adsorption and reaction (SILAR) method of preparing silver chloride cathode on the carbon felt is developed. The electrochemical behavior of the silver chloride cathode in the combination with magnesium alloy AZ63 anode is investigated, as the seawater activated primary cell. Under the discharge rate of the cell of 1C, 157 mA g−1 of active materials, the voltage discharge plateau of ~1.25 V–0.9 V; specific capacity of 130 mAh g−1; specific energy of 145 mWh g−1, and specific power of 175 mW g−1 are obtained.
