A salt water battery works by generating energy through the interaction between salt water and fresh water in separate compartments inside the battery system.
During discharge, the contact between these liquids creates an electrical current. During charging, the salt water and fresh water are separated again.
Salt water batteries often use materials such as manganese oxide and carbon-titanium phosphate as part of the electrochemical system.
Advantages of salt water batteries include:
Because they do not use highly flammable materials, salt water batteries are considered a safe and sustainable energy storage solution.
